Why doesn't my smartphone see the wifi network? Connecting a phone and router into a single network

Unlike wired network, Wi-Fi connection required additional authentication, since the connection to the network within the range of the signal emitted by the router is publicly available. Here, electronics are responsible for the Internet connection and there are no reasons why the phone cannot see wifi at home, there can be many: from ISP problems to router malfunctions. However, this problem is extremely common, and we will look at the most “popular” reasons that the phone does not connect to home wifi in this article.

Why the phone does not connect to wifi: establishing the correct “diagnosis”

So, if your phone does not receive Wi-Fi from the router, you should check:

• 1. Is the router frozen?.

Indeed, some of the reasons that the phone does not see Wi-Fi can be safely called mystical. After all, this is what all unexplained phenomena are called? In fact, all routers without exception periodically refuse to perform the tasks assigned to them, and even the manufacturers of this equipment cannot answer why this happens.

So, if your phone stops receiving wifi after fruitful work with a wireless connection, first of all you need to reboot the router. To do this, just turn off the device using the ON/OFF button on the device body (or unplug the power plug from the POWER socket), wait 30 seconds and reconnect the router to the power supply.

Thus, if the phone does not see wifi router due to its freezing, the problem will be resolved.

• 2. Correct phone authentication in the wireless network

If an authentication error occurs and the phone does not connect to WiFi, you first need to restart your mobile device.

• 3. Is the number of devices on the home network exceeded?

To find out why your phone doesn't see wifi at home, and see how many devices are allowed to use your wifi.

You may have turned on your laptop, tablet, phones, etc. and your router only supports 16 wireless connections to your home network.

Or, you bet too much, and the student from the next door decided to show his friends that he is a cool hacker. The young burglar picked up the password and gave it to his friends.

Unauthorized connections can be “banned” through the router’s web interface, after which be sure to change the password for accessing WiFi to a complex and unique one.

After changing the key, do not forget to delete all connections on your mobile communicators, and connect to the network with a new password.

• 4. Is the SSID repeated?

This is rare, but it happens. Some people either set a standard network identifier, or simplify the unique name to a simple one, for example, “dlink”, “tplink”, etc. If someone nearby also did not strain their imagination, then the next time they connect to home wifi network, an authentication error will occur.

Turn off your router and see if its name is in the list of available WiFi networks on your phone? If a network with the same name already exists, then change the SSID to a unique one, save the settings and reboot the router.

In this article we will look at why your Android device does not see WiFi ctmn in the list of available networks, although you are sure that it should be there.

This article is suitable for phones and tablets of all Android device manufacturers: Samsung, LG, Sony, Huawei, Xiaomi, HTC, ZTE, Fly, Alcatel and others. We are not responsible for your actions.

In this article we will consider a solution to the problem in which a tablet or smartphone on Android system suddenly stopped detecting Wi-Fi networks or one specific network. For example, let's take a smartphone that runs Android. Here he is perfectly connected to the home network, but at one point he simply stops seeing this network Wi-Fi.

This network is not in the list of categories available for connection. Other devices see and also connect to this network without problems. There may also be situations when no products see the wireless network at all. In such situations, you should check the router, then reboot it and see if the Wi-Fi indicator on it is blinking.

There are identical cases when in public places(shop, cafe, restaurant) other devices see and join a certain (often open) network, but your tablet or smartphone simply does not find it.

Increase

It doesn’t matter here whether you use a smartphone, tablet or even a TV set-top box. Let's consider the situation specifically for devices on the Android system. There is a possibility that if your gadget has stopped seeing the Wi-Fi network that it previously connected to without problems, then there may be a problem with the router (access point). If this is not your network (there is no access to the router), then it is unlikely that you will be able to do anything.

To avoid confusion, you should first find out the following:

• When a gadget does not see any Wi-Fi networks at all, but there are wireless networks in a given radius and other devices see them, then the problem lies only in the device itself. In this situation, you can do the following: turn off and turn on Wi-Fi again, reboot the gadget, remove the case. In extreme situations, you can reset the gadget settings to factory settings or flash the firmware. If even after resetting the device, no wireless available network does not see, then most likely the problem is related to hardware. The device must be carried in service center.
• The second case is more popular, which we will consider in detail. It's about about the situation when Android does not see one specific Wi-Fi network, but other devices find it and connect without problems.

Troubleshooting

First, let's look at the most simple solutions which should be done first:

There are very few options for a solution on the device. Rebooting, resetting settings, turning off, turning on the Wi-Fi network - this is the maximum that can be done directly on the Android device. There is another option - changing the wireless network settings on the router.

Changing settings on the Wi-Fi router

You can experiment with changing the Wi-Fi network channel, check the mode networking, change the channel width. Of course, these settings may vary depending on the router you have. Often they are located on one page in the router control panel menu: “Wireless”, “Wireless mode”, “Wi-Fi”.

In the settings you can, for example, set the 6th static channel or specify “Auto” if a static channel has already been installed. Then we save the settings and reboot the router. We take the gadget and check the visibility of the Wi-Fi network.

In the settings you can immediately check that the “11bgn mixed” mode is specified. You can change the "Channel Width". You should also check whether the region is specified correctly, if similar setup is in the router. The screenshot below shows an example of TP-Link router.

Increase

If after the first change of settings the gadget does not see the wireless network, then you can do it again. We set other settings. For example, a different operating mode (only n), channel. If there are no results, then it is better to return to the factory settings that were set before changing the parameters. You also need to return all the settings back when problems arise when connecting on other devices.

Setting up a virtual access point on a laptop to determine the network

There are also questions about why Android does not detect the Wi-Fi network that is created on the laptop. This is due to the fact that create virtual point access is not enough. After this, you need to enable discovery and open access to it.

It's easy to do. First, you should request to go to the Network Control Center. To open this center, you need to find the network icon in the tray (at the bottom right corner of the desktop). Click on it right click mouse, then a window will open, and the required item will be indicated in the menu that appears.

Increase

A menu will open where you need to enter the “Edit” section Extra options for general access." You just need to connect network discovery and give permission to share. The menu at the bottom should be disabled network access with password protection. You can also use software to create a wireless network on a laptop Virtual Router Plus.

Hello! Yes, I will write again about problems with Wi-Fi :). Someone needs to fight capricious wireless networks, which usually provide more inconvenience during setup than pleasure during use. Very, very many different problems arise, and most of them are difficult to even explain.

Today I will write about one of these problems. And I will give some recommendations that may help you solve it. But I can’t guarantee anything, I hope you understand.

What does the problem look like?

I think that after reading the title of this article, you can already understand what this article is about. I began to notice comments in which people wrote that their devices, be it a laptop, a computer with an adapter, a phone, a tablet, game console, does not see their home Wi-Fi network. It is simply not in the list of networks available for connection. Wherein, neighboring networks the device sees. But why? I thought for a long time, but could not come up with a logical explanation for this problem.

By the way, such nonsense can occur even after some work with Wi-Fi, that is, everything was working, you turned off the laptop (for example), and turned it on, but it no longer sees your network.

Here you need to act quickly and save your phone or other equipment from flying into a wall or window :)

Attention! This article is about when a device does not see a wireless network, but only one network, for example, while other neighboring networks are detected.

The device does not see Wi-Fi [possible solution]

Roman left the following comment on the site:

To be honest, I didn't know what to recommend. But then I thought again and realized that, as a rule, the most incomprehensible problems arise due to the channel on which the wireless network operates, or rather due to interference on the channel.

And I advised you to experiment with channels, as written in the article. Roman changed channel (unfortunately, he didn’t write which one he installed, but it doesn’t matter, you need to experiment) and everything worked for him. The laptop saw the network. A free channel can be determined using the InSSIDer program.

I don’t know if changing the channel really helped, or just rebooting the router 🙂 but the problem was solved. By the way, Reboot the router first if any problems arise. A simple reboot often helps.

There was also a comment where the game console stopped seeing the home wireless network. But I don’t know how it all ended.

You can also try experimenting with the mode of operation of the router, I wrote about this in the article.

Perhaps you have already encountered this problem and somehow solved it differently, or please leave your thoughts on this issue in the comments. And I will update the article and add useful material.

Bye everyone!

The laptop (phone, tablet) does not see the home page Wi-Fi network(sees neighbors) updated: February 7, 2018 by: admin

Nowadays, more and more often, to access the Internet, they use not a computer or laptop, but mobile gadgets, such as a tablet or smartphone. And there is an explanation for this - most of the Internet is used to visit sites, versions of which are designed specifically for small screens (social media VKontakte, Facebook, Odnoklassniki, Instagram), and you can’t put a laptop in your pocket. It’s good when the smartphone connects to the network via 3G or GPRS connection, then he doesn't need optional equipment, but if through a wired provider (for example ADSL or local network With shared access to the Internet), then the mobile phone first needs to connect to the router, and sometimes the router does not see the phone or another error is displayed, solutions for which will be discussed further.

By the way, mobile devices have several modes of accessing the Internet, some of which are for distributing it to other connected devices (access point mode).

Smartphone hotspot mode

There is also a 3G modem mode, in which the smartphone connects to the computer using USB cable, and thus the computer gains access to the network via a 3G connection.

But this article will discuss the mode of connecting a smartphone to a wireless Wi-Fi router, and in rare cases related problems.

Connecting your phone to the router

In order to successfully combine into computer network phone with a router, first of all you need to make sure that the router is turned on, Wi-Fi module is active and WPS is enabled (if available).

Found Wi-Fi networks

If the network is password protected, a window will open in which you must enter that password.

The password is entered only once, the phone remembers it and does not require entry during subsequent connections.

If there are no errors, the “Connected” status will appear under the network name. That's it, the phone is connected to the router's wireless network.

If you can't connect

But everything is not always so easy and simple, and for a number of reasons you cannot connect to the network.

Let's look at the most common cases:

1. In the router settings, check the “Hide SSID” checkbox.

Hiding a Wi-Fi network

If a ban is set, the router does not broadcast the name of the network, and to connect to it you need to enter the network name manually in your smartphone;

2. Standards do not match. For example, a router operates in the IEEE 802.11g 2.4 GHz standard, and a smartphone operates in the IEEE 802.11n 5 GHz standard. In this case, they will not be able to work in pairs; the standards must either match or be compatible;

3. The router settings may have a limit on the number of subscribers you can connect, and your smartphone simply turns out to be superfluous.

Limiting the number of subscribers

4. And, as practice shows, it’s enough common reason, it's just a router hangup. Turn it off and on again, it may help, but it won't make it worse. In this case, try updating the router firmware to a more stable one.

Third party software

We looked at how to connect your phone to a router without help third party programs, only using the phone’s own operating system. But there are programs aimed at helping in this matter. Let's give an example of one of these.

Appearance of the program

The program is called WeFi, you can download it on the program’s official website completely free of charge: http://www.wefi.com

I am very pleased with the multi-platform nature of the program. Choose operating system our smartphone and download the program to the computer, and then to the phone.

Selecting an operating system

For example, choose Android version. After installation on the smartphone, launch the application and see the initial window.

Initial program window

A big plus of this program is its funny animation. The little man at the bottom of the screen is frankly happy when he can connect to the Wi-Fi network without any problems.

But, nevertheless, the purpose of the program is somewhat different, namely to facilitate connection, and WeFi copes with this task perfectly.

Connecting the program

One of the main features of the program is automatic connection to the network with the most highest level signal. Of course, it can be configured for a specific network, but still the program is designed specifically for automation. The only thing is that you will have to enter the network password once, but without this there is no way.

Also very useful feature, as continuation of Wi-Fi activity after the smartphone goes into sleep mode.

Setting up the program

The only small drawback of the program is the absence of a blacklist; in some cases it may be needed (for example, in public places with paid but not blocked access).

The full operation of the program can be seen in the video review:

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 designed to help you identify the sources of these common problems and find the fastest and most effective way to fix them.

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.
• Action malware or antivirus software.

Below we will look at each item in detail and formulate recommendations for troubleshooting. All of the following is true for Wi-Fi on 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 point is configured Wi-Fi access. 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 because of something as small as wrong date- this is one of the first on the list of common causes of Internet problems. 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

Other possible reason- 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 antivirus program and conduct a check. 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 an error in Wi-Fi operation is due to failures in software, 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.
