Wifi does not turn on on Android. What to do if Wi-Fi does not turn on on Android


The Android operating system is feature rich and great amount applications allows this shell to occupy a leading position in the market. However, this system is not free from shortcomings: in the article we will figure out what to do if Wi-Fi on Android does not turn on.

Types of problems and ways to solve them

There are several reasons why Wi-Fi on an Android tablet does not turn on; however, people using phones controlled by the system also encounter similar problems. So, what are the roots of the problem and what to do if Wi-Fi does not work on Android.

Incorrect date and time

The first reason, which is quite rare, is incorrectly set date and time. To fix this, go to “Settings”, then “Date and Time”, and set everything correctly there.

Incorrectly entered password

This problem often occurs when there is password changed, But Android device“doesn’t know” about this. You need to go to the Wi-Fi connection settings, delete the network profile with which the connection was established and connect again.

Software glitches

The third reason why Wi-Fi on Android stopped turning on is software failures. You can try to solve the problem using special utility Wi-Fi Fixer. There is no need to change any settings in the program. Just download and install.

In the main window there will be information about the current status in the “Known” tab - all devices to which a connection has ever been made.

Settings error

Rolling back any firmware or Android update: Video

Viruses

Some of malware hinder normal operation radio modules. The solution to the problem is to scan the gadget with the built-in antivirus.

conclusions

If none of the methods described above helped solve the problem, then it is most likely in the module itself. In this case, the best way out of the situation would be to take the gadget to a specialized service center (if there is still a warranty) or to a workshop. Important to remember: serious interference with the operation of the shell in the absence of necessary knowledge creates a risk of turning the gadget into a “brick”, after which significant funds will have to be spent on resuscitation.

    There may be several options. The first is to simply restart your smartphone. Sometimes he just glitches. The second point is to do it general reset. Sometimes, due to some applications, there may be failures with wireless networks (for example, Virtual Router on Android introduces its own parameters that can cause failures). Well, if the previous two options did not help, then you need to flash it.

    Try to follow all the steps indicated in the article. If none of them work, then most likely the problem is in the module itself, as indicated in the explanation. If you can connect to another access point, try connecting. This will make it clear that the problem is in the device itself. Then you need to either change the firmware or use auxiliary utilities. In case to another point Wi-Fi access If the connection is successful, this means that the router itself is configured incorrectly. The main thing is to determine what exactly is not working correctly. When the location of the fault is determined, then it will be possible to look for solutions. Until then, it will be like reading tea leaves. Because you can look for a fault in one place, but in fact it will be in a completely different place.

    Is it possible to connect to the access point with something else? If the problem is not in the points described, then perhaps the cause of the malfunction is in the provider’s equipment. Most likely, the Internet simply does not reach the router. To check, connect another device to the router and check if it can connect to the network. If the result is the same as on the previous device, then you should contact your provider.

    Good afternoon. There are several questions. Firstly, it is installed on the tablet factory firmware or was it replaced by a third-party one? The latest version is installed on the device current version firmware? Is it possible to check the functionality? Wi-Fi module on your tablet by connecting to another access point? In order to most accurately answer the questions and find the most appropriate solution to this problem, you need to find out what exactly the problem is: in the tablet or router? Perhaps the problem can be solved simple reset to the factory settings, but to make sure this step is necessary, you should find out where exactly the fault is. Describe the problem in more detail and diversity. Very few firm conclusions can be drawn from the available information. But this is not enough to solve your specific problem.

    On my tablet, when I turn on Wi-Fi, the icon responding to Wi-Fi goes away towards the switch and remains gray and Wi-Fi doesn’t turn on... the same with bluetooth... I’m just trying to go online, the MTS website comes up and top up my account... although there is money in my account money... I reset it to factory settings... it didn’t help... I tried to connect to Wi-Fi in another place and it didn’t work either... what should I do???

    Hello! The problem is not common: Asus Zenfone 5 never had problems connecting via Wi-Fi to many routers. But now a problem has arisen - at the moment of connecting to the router and 5 seconds after that, the Internet is available, everything loads, but after 5 seconds the router seems to turn off the transmission of packets to the phone. But if there is a connection to the Internet (some website, updates, videos are being loaded), the Internet works well, as soon as you don’t let the phone download anything, the Internet turns off. This is very annoying when corresponding on VK, it does not update messages, since “there is no connection to the Internet,” but IF you turn on music in the same VK so that it loads, “the connection appears” (the Internet comes to life) and you can already chat.
    So why is this and how to fix it?
    I tried setting the DNS address to 8.8.8.8/8.8.4.4. also 77.88.8.8/ 77.88.8.1. . I also changed the channel in the router’s settings from 9 to 6. So far there have been no changes.
    I ask for help.

    Try to determine what exactly is not working: modules or software. To do this, send files via BlueTooth and Wi-Fi to another device. If everything works, check the settings yourself mobile internet. What exactly didn’t work when connecting to another access point? At what stage does the break occur? Connection? Authentication? Getting an IP address? How does the module behave when connected and did it work at all before? If yes, what caused the malfunction? Is there any contact with liquids that conduct electricity or mechanical damage? Need to more information to derive a specific answer for your particular case. Have you, by any chance, updated your device?

    Team V-ANDROIDE 09.28.2015 09:51

    Good evening! Did similar problems occur only when connecting to a Wi-Fi access point or when using mobile Internet too? If the problem is in the device’s firmware itself, then try resetting the settings to factory settings. In general, a simple reboot should help, but most likely it will not be enough. There is another option to determine which specific service is responsible for this behavior. And then roll back updates on it or clear the cache. In general, try cleaning the device auxiliary utilities. If nothing else simple methods If it doesn’t help, try more complicated and radical methods. You can also try restarting the Wi-Fi device itself. It may very well be that the problem is not in the gadget, but in the quality of the supplied network connection. If there are any irregularities in the work of the provider, the connection will work in a similar way. At first there will be access, but when the download is completed or stopped... The network begins to hang. There is simply no ping. And to get online, you either need to wait for an unknown amount of time or reboot the router. Have you, by any chance, updated your device? Try checking for updates. This can solve all problems, since when installing the OS, all auxiliary modules will be reset, installed and adjusted.

    What happened to the device before it started behaving this way? What caused it? Has there been any contact with electrically conductive liquid or mechanical damage? Have there been any updates or any resets or rollbacks? Launcher is used or stock tools? Is this a problem with the device itself or is there a slightly different reaction when connecting to another access point? Need more input information.

Is this a problem with the device itself or is there a slightly different reaction when connecting to another access point? Are you sure that the access point itself has access to the network? Try connecting to the router using another device. And not via cable, but via Wi-Fi. Or you can try rolling back the settings of the Wi-Fi module itself. Although it may very well be that only a reset, update or flashing will help. Need more input information.

In the evening everything worked, I set the tablet to exercise and in the morning the Wi-Fi button does not work. I've looked all over the internet and can't find the answer to my question. Wi-Fi is connected from other devices.

    Good afternoon. After locking the pattern in the phone, it was reset to factory settings in order to remove it. Before this, Wi-Fi worked. Afterwards Wi-Fi does not turn on, it needs to be turned on and does not turn on for a long time. The search button is not active. IP and mas addresses are not active. And the Wi-Fi device itself works. Catch the network on TV and other phones. Only it’s not on on mine? What should I do? I can fix it myself

    That is, the adapter itself does not turn on? Did I understand correctly? In this case, there are two options to repair this problem. In general, there are many options, but let's start with two. Firstly, did you read the article and watch the video? There is useful tips. Sometimes such problems happen due to viruses or applications that have access to control WiFi adapter ohm If it's a virus, then you have to do it full reset to factory settings, with formatting internal memory(and the flash drive, if you have one, is better to take it out for a while and scan it on a computer). If this app is just glitching, then uninstall it. Find the right application it’s also difficult if you have a lot installed applications. Therefore, it is easier for you to do a factory reset. Secondly, maybe the virus managed to make an erroneous entry in the system file, in which case even a reset does not always help. Here you already need to flash it. But there is no need to rush into this matter. First, try a reset. And if the reset does not help, then we flash the gadget. The firmware can be easily found on the 4PDA forum or on the Internet in general. 4PDA has instructions, firmware, drivers, programs for firmware and everything you might need. So go there. Well, if you doubt your abilities and are not sure that you can flash the gadget yourself, then go to the service center.

    Team V-ANDROIDE 10/19/2015 09:40

    Try using some third party app to WiFi control adapter. If resetting does not help, then firmware will help. Check if there are any other updates. Usually, if there are such problems after an update, then the developers quickly release additions and updates with fixes. If there are no updates, then flash the gadget manually. The 4PDA forum has everything necessary information. Search by your device model. There's probably information there. Moreover, people, most likely, have already encountered this and found some kind of solution. So your task is simply to find the right forum and topic. And then read and study.

    Good afternoon The device is Jiayu G2, old of course, but I was very pleased with it at one time and now I’m staying, but the Wi-Fi has failed. Official application“VKontakte”, stuck out of the blue (nothing downloaded, etc.), took out the battery, inserted it back and turned it on. As a result, wi-fi does not work at all, or rather, the icon for turning it on is not active. In the settings it is on “On”, but is not highlighted. When you turn it off and on, nothing happens. Yes, it’s Chinese and inexpensive, but I really want to fix it, so I’m thinking of reflashing it, I looked at 4PDA and thought a little, it turned out that this is not so easy on this model. But the desire to fix wi-fi remains, there is only one question - will flashing it help? Have you ever had similar cases? Thank you in advance.

    Maria 10/23/2015 20:44

    Good afternoon Help me please!

    Team V-ANDROIDE 10.29.2015 14:32

    Hello. I cannot answer your question definitively, since this could be either a software error or a hardware failure. If software error, then first try to do a general reset to factory settings, maybe this will help. If it doesn't help, then flash it. But if this hardware failure, then of course, the firmware will not help you, since in case of hardware problems you need to change WiFi module. Therefore, if you know how, then flash it. If the problem is in the software or OS, then the firmware will help. And if the problem is in the Wi-Fi adapter itself, then after the firmware everything will remain as it was and you will be 100% sure that the problem is in the Wi-Fi adapter itself. It is quite possible to replace it yourself; you must first find and buy exactly the same adapter (in size, model, form factor, connector, and so on). Well, if in doubt, then take it for repair.

    Hello. Let me clarify which access point is being used? It may well be that the tablet supports that WiFi standard, on which the access point works, but the smartphone does not support it. In this case, it happens that the device connects, but there is no way to use such a network, since there is neither the Internet nor local network will not be. I suggest you do an experiment, take your phone and try connecting it to another access point (friends, in public places(Internet cafe, etc.)) this will allow you to understand what is wrong with the access point or with the phone itself. If the phone does not work in any network (you need to check at least 5 different access points), then the beta is with the phone, but if it connects to other access points and there are no problems with the Internet, then the problem is in your access point. If the problem is with your phone, then reboot it. If this doesn't help, then do a master reset. If the cause of the error is in the access point, then you need to look at the settings, and for this I need to know what kind of access point you are using.

    Deleting the data file will not help, since this file appears automatically. It records all network data. Removing it will only reset the network data. That is, the problem will remain, but all passwords to previously connected networks will be deleted. That's all. The cure for your problem is either a factory reset or flashing. If these options do not help, then this tells us that the problem is hardware. This, in turn, means that you need to replace the non-working WiFi module with a new one. To do this, you will need to buy a new WiFi module (selected by model, form factor, connector, and so on). You have to take exactly the same one. If you doubt that you can choose, let alone replace, then bring it in for repair.

    Team V-ANDROIDE 10.29.2015 14:33

    Hello. Tell me, does the module itself turn on at all? Try moving your phone closer to the access point (router). If the phone does not detect the network even in close proximity to the access point, then the problem is with the module. Most likely it won't turn on at all. Try rebooting your phone. This usually helps. If rebooting does not help, then you need to reset to factory settings. I don't recommend you delve into files. Because from what you can find, this is a file about passwords and network parameters. But removing it will not help you. If this is a software failure, then it can be solved by resetting the parameters or flashing the firmware of the device. If this is a hardware failure, then it can be solved by replacing the WiFi adapter (by disassembling the device).

    Hello. For what reason did you do a general reset? If there were problems with WiFi, then most likely it was a hardware issue. This means that you will have to replace the WiFi adapter in your tablet. Try downloading third party application to manage a wireless network (and WiFi module). If it doesn’t help, then, as a last resort, you can try to flash the gadget. If this does not help, then replace the WiFi module itself. Moreover, if your tablet is still under warranty, then take it to the service center. If not, then try flashing it. Again, if the firmware does not help, then you are unlikely to be able to change the WiFi module yourself, so it is better to take it for repair, it will cost less than if you aggravate the situation by trying to fix everything.

    Team V-ANDROIDE 16.11.2015 14:09

    Hello. Have you replaced the screen yet? The fact is that broken screen may cause similar failures. A damaged surface can itself issue various commands without user intervention. For example, you try to turn on Wi-Fi, and the screen immediately sends a command to turn it off. Well, it’s the same with BT. If you replaced the screen, then of course the reason is different. If you did a reset and the problem still remained, then most likely the problem is in the hardware. But no one is stopping you from trying to flash the gadget. Just download the firmware that is currently installed (the same version and, most importantly, the original official one). If the firmware does not help, then you have nothing to lose, because the firmware will remain official. In this case, you will simply need to replace the WiFi and Bluetooth module (they are often combined on one board, but there are also separate ones). In general, I won’t tell you for sure whether your problem is hardware or software. Personally, I'm leaning towards hardware (replacing modules), but to be sure, it's worth flashing.

    Team V-ANDROIDE 16.11.2015 14:12

    Hello. You may have two reasons for this problem. 1. Software glitch. 2. Hardware failure. In the first case, there are several solutions. I understand that you tried all the instructions in this article, but nothing helped. Did you do a master reset? If not, then do it. If it doesn't help, then it's most likely a hardware problem. But to be sure of this, you can try flashing your device. At the same time, use only official firmware (old or new - it doesn’t matter, the main thing is official and better tested, that is, not the newest, but not the oldest, something newer, but already tested). If the firmware does not fix the problem, then the problem is hardware. To solve the hardware problem, you simply need to replace the WiFi module. To do this, you will still have to contact a service center. You can try to replace it yourself, but now there are a lot of defective and counterfeit modules. so you can buy a defective WiFi adapter. Yes, and you need to choose not only by model, but also by modification, form factor, connectors, and so on.

Will you be able to enter the router settings? Here is an article that describes the main provisions - http://bezprovodoff.com/wi-fi/oborudovanie/wifi-dlya-doma.html. If you don’t want to flash the firmware, then reboot the router (often this is enough) or reset all parameters to factory settings and configure everything again.

    Friends! Today I encountered a similar problem on the Samsung G531-H, which I just didn’t do with the smartphone, all that remains is to reflash it. But! I have the “wonderful” CM Security antivirus installed, which it considered a threat to the phone’s connection to the Wi-Fi and Bluetooth networks.) The application itself blocked access to connecting to any network, and the switch slider jumped off the icons in the same way. The solution was this: if you have the same antivirus installed, then go to the right top corner to the “menu” icon –> AppLock (enter the password if you have previously set it) –> Switches (open the lock with Wi-Fi and Bluetooth). Ready! 😀

    Hello. Check your router settings. In particular, you need to edit WiFi settings(local network). Here it is important to install the Wi-Fi standard 802.11b\g\n mixed and the data encryption type WPA\WPA2 mixed. In addition, try switching Wi-Fi broadcast channels. If all else fails, then try to reflash the router, but after that you will have to reconfigure it again. You can try resetting the settings on the phone itself to factory settings. But, in this case, you will lose all data from the internal memory on your phone. I don't see any other options.

    Hello. If I understand you correctly, then you are trying to reset to factory settings, and an error occurs during the process? If so, then in this case you need to flash the gadget. And it’s worth using service firmware. If you don’t find a service one, then simply use official firmware. If you doubt that you can flash your tablet (or smartphone) yourself, then it’s better not to try, as you can only make things worse. In this case, it is better to immediately contact the service center.

    Team V-ANDROIDE 12/14/2015 14:17

    Hello. It wouldn't be bad if you could clarify what kind of device it is? What firmware? What router do you have at home (or what are you trying to connect the gadget to)? I can't help you without knowing this information. Similar errors can occur due to various reasons. Try setting network settings manually on your phone (tablet). Also in the router settings, you can check the Wi-Fi settings, set a different channel, select a different type of data encryption, or assign a different Wi-Fi broadcast standard. You can check this way - go into the router settings and make the network open (that is, so that there is no password for connecting). If the phone connects and works normally, then the problem is in the type of encryption. In this case, in the router settings, simply select the type of encryption that is supported by the phone, and everything will work. If the problem is in the standards, then the router should be set (if possible) to the b\g\n mixed standard. Well, there are many other things that can cause problems with connecting to Wi-Fi.

    Hello. Based on the symptoms described, most likely, either the driver for the WiFi has failed, or there is a glitch in the firmware, or the WiFi adapter itself has burned out. You cannot rewrite the driver yourself. Therefore, there is a way out - try to reflash your phone (use only the official service firmware). If you cannot do this yourself, or the firmware does not help, then take it to the service center. You are unlikely to change the adapter yourself. If the firmware does not help, then there is clearly a hardware problem and you just need to replace the Wi-Fi adapter.

When I went through the settings, Wi-Fi was turned off and the power button was gray. Same with bluetooth. I read a lot about this on your website, I reset the phone to factory settings. It didn’t help. Wifi Fixer didn't help either. I also don’t want to reflash it because... We are expensive. Help please

    Please tell me what wifi problem turns on and off spontaneously Android Samsung J7. The trouble is that this happens when connecting to networks with fiber optics, but when connecting to old Wi-Fi lines works without problems. I reset the settings, sent it to the service center (they said everything was fine), installed Wi-Fi programs fixer, Manager, changed the settings in the modem, nothing helped

    Hello. Please tell me, Wi-Fi, access point and bluetooth have stopped working on the Lenovo S650. The Wi-Fi icon keeps blinking and won't turn off. But the access point and bluetooth do not turn on. I did a factory reset once, but nothing changed.

    Good evening, I have a DEXP phone, apparently some new company... I don’t understand what’s going on, I connect Wi-Fi, but it’s gray and doesn’t work, it’s been 3 days now. Works on other devices. Help me please.

    Hello. It could be anything. Perhaps one of the applications has access to network settings and is blocking Wi-Fi, perhaps malware has damaged system file entries, and so on. First you need to check the host file. It should only contain one entry. Here are the instructions - https://www.youtube.com/watch?v=amryBG6LYbs. Edit the entry in this file (if there are any changes there) and everything will work. If this doesn't help, move on. You can try doing a general reset to factory settings. If this does not help, you will have to reflash the device. It is best to use the official service firmware. This is the most best option. If you can’t flash it yourself or are afraid, or the firmware didn’t help, then bring it in for repair, as most likely it’s a hardware problem. That is, you just need to replace the Wi-Fi module.

    Team V-ANDROIDE 03/11/2016 09:54

    This could be either a software error or a hardware failure. The first thing you need to do is reboot your gadget. Usually this is enough. If rebooting doesn't help, then move on. To check whether it is a hardware or software failure, you need to perform a master reset to factory settings. This will reset all settings and all crashes. But, you need to understand that you will lose all the data that is saved in the gadget’s internal memory. Therefore, save everything on your computer first. If a general reset does not help, then try flashing the device. If you doubt that you can do this yourself, then seek help from those who know how to do it. If after resetting and flashing WiFi devices It still won't turn on, then it's a hardware problem. This suggests that you just need to replace the WiFi module. To do this, you will have to find and buy a suitable module (by size, connector, standard and model), disassemble your gadget and replace the broken part with a new one. Again, if you doubt that you can do this yourself, then take it for repair or to knowledgeable people. If the gadget is under warranty, then immediately take it to the store where you bought it.

    Hello. First, check whether the security password you entered is correct. If everything is correct with it, then the problem may have arisen due to incorrect settings router. The fact is that modern Wi-Fi routers support DHCP technology. This means that all data about the router connection is automatically sent to the phone. This is exactly what smartphones and tablets are aimed at. If you disable this function, the phone will not be able to obtain an IP address and, accordingly, connect to the network. The solution to the problem is to enable this feature if it is disabled.

    Team V-ANDROIDE 03/16/2016 10:44

    Hello. What do you mean fiber optic networks or regular old lines? What network are you using? The fact is that it does not matter how the router is connected to the network. After all, the phone communicates with the router, and not with the provider. And the router already provides Internet access. But, if you have already contacted the service center and they didn’t help you, then I don’t know what else to suggest. I don’t think I can do more remotely than specialists can do in person. And I have nothing to do with fiber optics. I have the most common cable from my provider.

    Jasmine 03/27/2016 20:10

    Thanks a lot! I solved my week-long problem in 2 minutes... Wi-Fi wouldn’t connect on my old phone, although I hardly used it and didn’t pay attention to the date. And the year was 2013. I urgently needed to go online, the new one was dead, but nothing worked. Thank you))

    Hello guys! I had a problem connecting to the Internet via wifi after I reset my miniped to factory settings. Wifi is connected but the provider's website does not open. Before the reset, everything worked, and everything works from other gadgets. What is the reason for this problem? Thank you!

    Good afternoon Lenovo A516 had no problems with Wi-Fi before. Now it says the status is “Connected” but there is no Internet. I tried from three access points that previously connected without problems, the result was the same.

    Hello! GOgoclever TABLET (tablet) turn on Wi-Fi, enter the password (I don’t know, I’m still young) I think, well, I press “connect” correctly, it says connection then authentication authentication took a very long time to load for half an hour and still didn’t connect, what should I do?

    Team V-ANDROIDE 05.25.2016 13:06

    Hello. Apparently some application does not allow you to disable WiFi, or there is simply a glitch in Android work. In any case, this problem is solved by resetting to factory settings -. You can, of course, try to search for records in system files(in particular, in the host file – https://www.youtube.com/watch?v=amryBG6LYbs). Or find an application that creates such errors. But it’s not a fact that you will be able to find the root of the problem and fix everything. At the same time, you will spend a lot of time and effort. Therefore, it is better, easier and faster to do a factory reset.

    Hello. First, I recommend checking the host file – https://www.youtube.com/watch?v=amryBG6LYbs. If the instructions described in the video tutorial do not help, or you cannot follow them, then you can simply reset to factory settings -. There are no other options. The fact is that Android devices do not have settings like on a computer; you cannot reinstall drivers or reset the network cache. Reboot your phone, if that doesn't help, do a reset. If resetting doesn’t help, then all you have to do is flash it yourself or take it to repair.

    Team V-ANDROIDE 05.25.2016 13:07

    Hello. Read this article -. In general, you need to be careful when entering your password. It is quite possible that you entered the password incorrectly. Also check out this material -. In general, if you cannot solve the problem yourself, then contact someone who can help, show and explain. It is impossible to do this remotely, since first you need to understand at least the basics in order to understand what we are talking about we're talking about. It's better to ask someone to show you how to use WiFi on your tablet.

    Hello, just yesterday everything was fine, I have a Lenovo A536, I connect to Wi-Fi, it says connected but there is no Internet, I haven’t done anything and restarted and checked everything perfectly, sometimes during the day it appears literally for 30 seconds. On a laptop Wi-Fi works perfectly. Please tell me. Thank you very much!

    Team V-ANDROIDE 06/01/2016 20:54

    Hello. First, try restarting your tablet. If rebooting does not help, you will have to do a factory reset -. If resetting doesn’t help, then all you have to do is reflash – . Personally, I do not recommend that you reflash your gadget yourself. It is best to seek help from more experienced people who can easily flash your tablet. It is worth noting that it is possible that the firmware will not help. The fact is that the problem with the WiFi adapter may be hardware. That is, the WiFi adapter (board) itself burned out. In that case, you just need to buy new WiFi adapter for your tablet, disassemble the tablet and connect a new adapter instead of the old one. Again, I do not recommend doing this yourself, unless, of course, you have experience in this matter. It's better to contact a service center.

    The Wi-Fi power button has become dim, it turns on for a long time (3-5 minutes) and the message “turn on Wi-Fi...”, and then it turns off, sometimes it connects to Wi-Fi, but this happens rarely. LG Spirit, android 5.0.1 drain, reset settings are not for me

Every user sooner or later is faced with the fact that for some reason Wi-Fi does not work on the phone. This article is intended to help identify the sources of these common problems and find the fastest and most effective method their elimination.

Malfunction wireless communication, as a rule, caused by several reasons:

  • Wrong specified settings Wi-Fi.
  • Errors in the operation of the router itself.
  • Incorrect mobile device parameters.
  • The action of malware or antivirus software.

Below we will look at each item in detail and formulate recommendations for troubleshooting. All of the following is relevant both for Wi-Fi on an Android phone, iOs, and for other operating systems.

Troubleshooting

You can cope with the problem only if you accurately determine its cause. To do this, you do not always need to contact specialists. Many errors that concern, for example, parameters wireless mode, you can identify it yourself. If the Internet slows down or works slowly, this may be due to third-party factors: for example, network overload when many gadgets are connected to it. Sometimes slow Wi-Fi is a reason to check the computer itself or the communication line of your Internet provider.

Incorrect Wi-Fi setting

First of all, you should pay attention to how the Wi-Fi access point is configured. To do this, you need to access the router menu through a browser: but you will need to enter address bar a series of symbols, the combination of which is individual for each device. Typically this data is located on back side router, look for the Login and Password lines, they will be needed in the next step.

Enter your username and password. If you managed to gain access to the menu, first of all you should pay attention to the wireless mode parameters. There are a few simple options here:

  • Channel - Auto, but you can try setting a different channel.
  • Mode - 11 bg Mixed, but changing the parameter to 11 bg only can give a positive result.
  • Channel Width - auto.
  • The transmission speed, if any, is set to the maximum value.
  • Region has little effect, but theoretically it can be a source of malfunction.

If everything is configured correctly, but the Internet still does not function correctly, you should contact a service center or look for the problem elsewhere, for example, by contacting your ISP. The device may be technically faulty, so it is recommended to check it immediately after purchase.

Router settings

You should check whether it is possible to access the Internet at all. If she doesn't exist, what about personal computer, and from another device, it is advisable to check whether the router itself is turned on and whether it is working correctly. Indicators signal this.

The power indicator should be green. Next to it is a system indicator that should blink. The next indicator, WLAN, shows whether wireless is enabled on the router itself or in its menu. Next are numbered LAN ports, to one of which a cable must be connected. Ideally, it should also blink. After them usually comes WAN, the indication of which indicates that the router is connected to the Internet.

In some cases, reconnecting helps.

Incorrect time or date

Wi-Fi on mobile device may not function well due to such a small thing as an incorrect date - this is one of the first on the list of common causes of problems with the Internet. You just need to go to the time settings section and set the correct values. It is important to take into account the time zone correctly.

Wi-Fi password error

Another possible reason is the password. If the phone connects to the hotspot automatically, this error occurs when the user changes the password. In other words, the password has been changed, but the gadget itself “does not know” about it and automatically enters the old one. The solution, again, is simple - create the connection again and enter the correct password.

Malware and antivirus programs

Interfere correct operation Wi-Fi can also be caused by viruses that the smartphone “caught” on the network. If you suspect an infection, it would be advisable to install an antivirus program on your phone and run a scan. There are many such programs, but they usually use established brands like Kaspersky and ESET Nod.

The other side of the coin: antivirus and other security programs, such as a firewall, can themselves be a source of problems. The antivirus creates a kind of “shield” to filter traffic, which sometimes affects communications. If after removing the anti-virus software the connection works correctly, in this case you will have to try another software or abandon it.

Software glitches

Many users experience wireless connection problems due to incorrect operation software. For example, when the user installs alternative firmware or any other interference is carried out with the factory characteristics of the software.

Problems with the Android system are also indicated by other errors in the operation of the gadget - constant, systematic freezes, random shutdown and others.

In this situation, you can do a Hard Rest - it will return the system to factory settings.

If the problem is with the phone's firmware, this will help solve it. But you need to know that “non-native” firmware is not deleted in this way.

When the source of incorrect operation lies in the router, you often just need to reboot the router. This is not always easy to do, since some models are not equipped with an on/off button.

If the device itself does not have a reset function, you can simply unplug the cable for 10-30 seconds.

It can also be done through the device menu. The procedure for entering there is described above. This method This is relevant if it is difficult or impossible to get to the router itself. "Reboot" option in different models routers is located in different parts of the menu, but, as a rule, on the system settings tab.

If the error in Wi-Fi operation is due to software glitches, you can try rebooting the device. In addition to the standard “Restart”, there are several more radical and thorough methods:

  • Through the menu: “restore and reset”.
  • By entering the number *2767*3855#.
  • Through Recovery Mod- it can be called by simultaneously pressing “Home”, “Power” and volume down. Next, select the “Wipe data” section.

Other problems

If these recommendations did not help restore normal functioning wireless connection, maybe it's a matter of technical malfunction the Wi-Fi module itself. In this case, only a qualified specialist can help.

Ask a question to a virtual expert

Conclusion

Issues with the functioning of Wi-Fi, as a rule, can be resolved easily and without the involvement of specialists. But it is worth remembering that independent technical intervention can damage the machine to the point of complete loss of functionality. If connection difficulties are not resolved accessible ways, it is better to contact the service center.

Video

A lot of users, when trying to connect their Android smartphone or tablet to a Wi-Fi network, encounter many different problems and errors. In this article, we will try to deal with the problem that appears after connecting the Android device to Wi-Fi. When Wi-Fi does not work on a smartphone or tablet. More precisely, the Internet does not work when connected via wireless network. A very popular problem.

Connected your smartphone to home Wi-Fi network, or at work, there is a connection, but the Internet does not work. Websites do not open in the browser, Google Play Store does not work, other applications that require Internet access also refuse to work. True, there are exceptions when, for example, sites open in the browser, but the Play Store does not work, and the YouTube video does not play. Usually, wifi icon in such cases it is gray and not blue, as it should be. We will also talk about this.

When many people write that Wi-Fi doesn’t work on their smartphone, what they mean is that Android connects to Wi-Fi, but doesn’t load anything. If your mobile device does not see any Wi-Fi networks, or some errors appear when connecting, then this is a completely different topic; we will definitely talk about these problems in other articles. Or, check your router if it is . Now we will consider exactly the case when Wi-Fi Android smartphone Connects without problems, but there are problems with Internet access.

In fact, there are many reasons and solutions. The whole difficulty is that the problem can appear either due to some problems in the settings of the tablet or smartphone itself, or because of the settings of the router. We will first check whether the settings on the mobile device itself are correct, and if this does not help, then we will change the settings of the router.

Android: Internet via Wi-Fi does not work. Solving a problem on a smartphone

If you have a tablet, then these tips will also apply.

1 First of all, you can try turning off/on Wi-Fi on the device. Enable/disable airplane mode. Reboot your smartphone. Sometimes it helps.

2 Checking proxy server settings. If a proxy server is enabled on your smartphone in the properties of your wireless network, then the internet will not work. You need to check, and if it is enabled, then disable it manual setting proxy servers. Go to settings where the list is displayed Wi-Fi networks, and the network you are connected to. Usually, you need to click on the desired network, and hold it. A menu will appear in which you need to select something like Change network. Next, you will most likely need to check the box next to Additionally. The proxy server setting will appear. It should be disabled. See screenshots, yours may be slightly different.

If it is set to “manual”, then the Internet on the phone will not work.

3 Check the date, time, and time zone settings. These are the parameters due to which the Play Market most often does not work on Android, wifi icon gray , and the Internet does not work in other programs.

Your phone or tablet should always have the correct date and time settings. It is also recommended to use the 24-hour time format if you have it disabled. Be sure to check these settings on your device. You can set it to automatic.

After proper setup, the Play Store starts working. This has been verified.

4 There is such an application - “Freedom”. If you have it installed, then in the application itself you need to click Stop. And if you deleted it, then install it back, go to the application, click Stop and then you can delete it. I haven’t encountered this myself and haven’t tested it. But many people write that it helps. The Internet starts working.

5 Setting up automatic IP acquisition. When there are problems with IP, Android usually does not connect to Wi-Fi at all. But it doesn't hurt to check.

Open the Wi-Fi settings on your device and go to the properties of your network (as I showed above). By checking the box next to Advanced (you may not need to do this), you will see the item IPv4 settings, Or something like that. It should be displayed there automatic receipt IP - DHCP.

6 I saw reviews that help a lot of people setting static DNS addresses. This method helps in cases where you have a gray Wi-Fi icon on your smartphone or tablet instead of a blue one, and the Market does not work. Also, not all sites may open.

Go to properties required Wi-Fi networks, as I showed above. Check the Advanced box (if it is needed) and find the item IPv4 settings (yours may be slightly different). You need to select an item Manually, and find the fields DNS1, And DNS2. Write the following addresses in them:

You can also change the DNS in the router settings, if it makes it easier for you.

7 You can do more Full reset of your Android device. If you are not too lazy to configure it again, install applications, etc. But, if nothing helps, then you need to reset it, this can solve the problem with the Internet.

8 Update. In the comments, they shared unusual tips that helped get rid of the Wi-Fi problem on Android. The solution is really very strange, but you can try.

You need to select in the phone settings as the main memory phone's built-in memory, not an SD card. I can’t specifically tell you where this can be done on your smartphone. Maybe you don't have such a function at all. But look somewhere in the settings, in the "Memory" section.

Change the router settings if the Internet does not work on your smartphone (tablet)

Let me remind you once again that the Internet from your router should work on other devices. If it does not work at all, on any device, then you need to configure the router. Android has nothing to do with it. Basically, the tips that I will write below help in cases where the smartphone does not see the Wi-Fi network at all or does not connect to it. By the way, before setting it up, you can simply try rebooting the router.

1 Try changing the channel in your router settings. Very often, it is because of the channel that problems arise with connecting to Wi-Fi. There is a detailed article on this topic:. You don’t even have to look for a free channel (this takes a long time), but simply install some static one, for example - 6. In the article at the link, I showed how to change the channel on different routers.

2 On the same page where you can change the channel, you can usually change the region. These settings are usually located on the Wi-Fi network settings page. Set your region in settings.

3 Here you can also try changing the wireless network operating mode. These settings are available on any router. You can try different variants. For example, put n only.

Here you need to experiment. Don't forget to save the settings and reboot the router.

Ask questions, share your tips and solutions in the comments!

We all use the Internet while in cafes or restaurants, with friends, even at home at the dinner table, checking mail or messages on VKontakte. As practice shows, one of the most common problems arises when working with wireless technology Wi-Fi. Let's say our access point is located in the house from the router or in a public institution. Everything seems to be configured correctly, but for some reason there is no access to the network.

So, what to do if you encounter such a problem? In fact, there may be a dozen reasons, each of which we will consider in this material!

Wi-Fi on Android is turned on, the status is “Connected”, but there is no Internet access

Let's say that you activated on your smartphone Wi-Fi and connected to the access point. Your phone displays the “Connected” status, but you cannot access the Internet, either using a browser or through other programs, for example, Odnoklassniki. What should we do in this case?

First you need to check whether the Internet works for this connection at all. That is, you need to gradually weed out the list using the process of elimination. possible reasons and checking the Internet is the very first of them.

Try connecting to this access point from another device and go online. If everything is fine, then the problem is in your smartphone. If another device does not connect to the Internet or does not open websites, then the problem is with the access point or router itself.

Solution 1 – Correctly setting up your router for Wi-Fi

First, check if your smartphone is within range of a wireless network. Typically, routers can distribute a signal up to 200 meters, provided that there are no obstacles within this radius. If everything is in order with this, then move on to the router settings.

Change the channel your access point is on. Usually it is set to Auto, but we advise you to set it to channel 6 or another. Select any of the available ones, save the changes and check the functionality.

You can also change the operating mode for Wi-Fi. As practice shows, by default the 11bg mixed mode is usually set everywhere. Change it to 11n only.

If you have a column in the settings for specifying the region, then be sure to set your region there. This is a minor parameter, but in very rare cases even it can affect the correct operation of the access point.

Solution 2 – Setting up a proxy server

Another one possible problem- This automatic selection and setting a proxy server for a specific access point on a wireless network.

To fix this:

  1. Go to Settings on your device
  2. Next, select Wi-Fi or “Wireless Networks”, depending on the version of Android
  3. Find the access point you are connected to and hold your finger on it for a few seconds. will appear extra menu, in which you need to click “Change network”
  4. Check the box next to "Advanced options" and select "Proxy settings"
  5. All that remains is to check the box next to “No”, after which the proxy server will be deactivated

Wi-Fi is enabled on Android, but Google Play and other apps are not working

If Wi-Fi is activated on your smartphone and it is connected to a certain access point, but the phone does not open websites, does not load pages and applications in Google Play– check that the time and date settings are correct. This is a very common user mistake! In 90% of cases, it is this that causes connection problems.

You just need to set the time and date correctly, reconnect the Internet, then try to log into Google Play and view one of the applications on the page.

Why Wi-Fi doesn't work on Android: other reasons

  1. Incorrect password. Sometimes the Android operating system stores the password for a certain access point, but when you subsequently connect to it, no notification appears that the password is incorrect. We advise you to check the correctness of your entry and change it if necessary. As you understand, in public places it is usually open points access, but there are also closed ones. To guess the password for them, you can use special programs, for example, from the same Google Play, where users share information around the world.
  2. Software problems. Another common reason that is related to software your system. To check the correct operation, you can use Wi-Fi app Fixer. Just install it on your device and run it. There you can also view full list networks that have saved data that you have previously connected to. Restart your phone and try connecting to the hotspot again.
  3. Malicious applications. There may be viruses or Trojans on your phone that are blocking wireless networks. In this case, you will have to manual mode install an antivirus, for example, Kaspersky.
  4. Incorrect settings. We have already talked about setting up Wi-Fi networks. If you can’t change them, you can simply reset to factory settings. You may also have old entries about the access point. For example, you connected to it, as it says in the system, although the connection was not actually made. Just update the list of networks in the settings or delete everything and try updating again, and only then connect to a specific Wi-Fi point.

But what should you do if Wi-Fi is connected, but the Internet still does not work even after all the recommendations described? Most likely, your Wi-Fi module itself is not working correctly. The following will help:

  1. Phone firmware, if the reason lies in the software part of the smartphone. If you don't know how to stitch yourself OS Android, it would be better to contact a service center.
  2. Repairing the Wi-Fi module. If the phone's firmware does not help, then the problem lies in the wireless network module itself. In this case, you will have to take the smartphone to a service center and have the parts replaced.

This is not a complete list of reasons that cause failures in Wi-Fi work. If you have encountered similar situations and you solved them in some other way, be sure to tell us about it in the comments for our readers!
