The phone does not see home wifi, what should I do? Android phone does not see WI-FI from laptop

The router works properly, as all phones and tablets connect to it perfectly. The catch is this: the laptop sees all the surrounding Wi-Fi networks, but it doesn’t see ours. I read the forum and some people encountered a similar problem. You write to check the driver in the task manager in the control panel. I have Windows 7 and I don’t see this at all. Please, please describe my actions in more detail. Thanks in advance.

  Apparently we are talking about a driver for the Wi-Fi module, which can be downloaded from the laptop manufacturer’s website. But you better first make sure that the desired channel is installed on the router, on the tab responsible for WiFi. If it says “Auto”, then this may be the reason.

  • Nikolai

    To get started, simply remove the wi-fi adapter in the device manager and update the equipment so that it can be found again. My problem was solved like this.

    “You better first make sure that the correct channel is installed on the router, in the tab responsible for WiFi. If it says “Auto,” then maybe that’s the reason.” And how to do it? Can you explain it to a stupid person?

  • SMARTRONIX

    For Android phones there is a “wifi analyzer” program, download it and install it, find your network using this program, the channel is displayed there (designation CH), if you turn off the router and turn it on after a minute, then when you analyze it again, the channel may be different. .To. The router automatically selects the least loaded one.
    Also check if your laptop sees other networks and can it connect to them?

  Hello. I have the same problem, PDA distributor HTC HD2 Windows Mobile 6.5. I turn on the wi-fi distributor, everything works well, the signal level in the form of an antenna, 2 weeks have passed, the icon instead of the antenna has changed to a triangle in the form of three computers, the laptop on Windows 7 sees normally. Another laptop on Windows 8 stopped seeing the network, although it sees other networks normally, the tablet on Android doesn’t see it either. Restoring the factory settings did not help, setting up wi-fi still does not help, flashing to another firmware does not help, returning to the old one, no changes. tell me what to do. thanks in advance.

• Vania

  Hello. My laptop on Windows 8 doesn’t see any wifi network, I don’t know what to do. My mother’s laptop sees it, my phone sees everything else too, but my laptop doesn’t. Help me, what should I do?

• Catherine

  Hello. I bought a router, all devices in the house were connected. Then all the settings merged, I reset the router to factory settings, configured
  network, as a result, the tablet, the phone sees the network, and the laptop sees it, but in a limited way. What problems might there be?

• Nika.net

  Please tell me this question:
  My neighbor has a network without a password, I find it and successfully connect with a laptop with Win XP, but I came with a laptop of the same model with Windows 7 installed, but the neighbor’s wi-fi is not visible. The e-reader sees it, the laptop with XP sees it, but the laptop with 7 does not see this unprotected network, although it sees all the other neighboring ones with a password just fine. I've already tried everything, but I still can't see this network, but I can see the others.
  What can you do, because there is no access to the router))

• deps

  Windows 8 sees wireless networks operating up to channel 11 inclusive. In the settings of the Wi-Fi router or access point, change the channel to any one from 1-11, and everything will be fine.

• Dmitriy

  Hi all. I have a similar problem.
  The router is working. 3 devices see it and work well. The 4th device (laptop) sees other networks, but does not see mine. I distributed wifi from my phone - it sees and works. On an XP laptop. What do they eat this with?? Where to look and what to turn. Help with advice if you're not too lazy. Thank you:)

• Tarkus

  I had the same thing, just now. I came across this topic. Maybe I can help someone.

  The laptop stopped seeing my router, my neighbors saw it and connected, my other devices connected to the router normally.

  In short, I solved the problem by choosing a connection, there is such a topic in the router settings, such as b, bgn, bg, n. I put n, read that it is the fastest and everything was found)

• Nikk

  Everything worked perfectly. But unexpectedly, a certain Wi-Fi network disappeared. The laptop sees the rest of the networks, but not the one it needs. However, the phone perfectly catches this network and connects to it. And it works fine with it. But the laptop does not see it. To other networks The laptop can connect. However, it does not want to connect to its native one.

• Hellen

  Good afternoon, tell me, my laptop doesn’t see my Wi-Fi, it sees all the neighboring ones, but mine doesn’t, if you connect the wire directly to the laptop, the Internet works. What should I do? I’ve already found similar problems here, but I still don’t understand what needs to be updated there and how I can solve this problem, please explain in more detail, I’m not very good at setting up laptops. Thank you in advance.

  good afternoon, there is such a problem, the tablet cannot find the Wi-Fi point in the phone, although my point in the phone is visible through the laptop and another phone, what should I do?

• sea

  My WiFi does not see ONLY my network on my laptop, does anyone know why? Shows there are 15 neighbors' networks in the house, but not mine! Is there something in Windows or the registry that needs to be deleted? (There is a router. On a Windows XP laptop. Moreover, a netbook, 3 phones and a tablet work via WiFi).

Articles and Lifehacks

It is very difficult to imagine a modern means of mobile communication without the ability to browse Internet pages. This function can be used using a connection under the Wi-Fi Alliance brand - this service is wireless. That is why such a connection is considered the most convenient and advantageous. It is implemented on the foundation of the IEEE 802.11 communication standard. The abbreviation Wi-Fi is derived from two words “Wireless Fidelity”. This phrase can be translated from English into Russian as follows: high accuracy of wireless transmission of information. A huge set of standards for streaming data transmission has now been widely developed. They are transmitted over a variety of radio channels. However, not all communication subscribers can use Wi-Fi. Firstly, the mobile phone must be equipped with an appropriate chip. Secondly, not all users know how to use Wi-Fi, even if their smartphone has this function. They often complain that they are the phone does not see wifi. What to do when the device does not see Wi-Fi?

The mobile phone did not see Wi-Fi - why is it needed?

First you need to figure out why you need a Wi-Fi connection? To answer this question, you need to have an understanding of the simplest benefits of Wi-Fi communication. Only then will it be possible to answer why the phone does not see wifi? It is wireless communication that allows you to use the network without cable. There are excellent savings on the cost of installation, deployment and expansion of the Internet network. After all, there are many places on Earth where it is impossible to install or lay a cable at all. Wi-Fi allows mobile device users to have the most convenient access to the Internet almost anywhere. Wi-Fi can also fully guarantee the compatibility of several equipment of different directions. Wi-Fi is valued primarily for its portability and convenience. If the user wishes on the beach, then he receives it via Wi-Fi. This communication opportunity is even more valuable due to the fact that several users of mobile phones, computers, tablets and laptops can access the Internet in one Wi-Fi zone. Today, even a powerful Wi-Fi device has much less radiation than one mobile phone.

The phone did not see Wi-Fi - look!

Users often complain that the phone does not see Wi-Fi. Although it finds various other access points. Even checking the Wi-Fi router doesn't help. The fact is that the router selects the channel automatically. If the phone does not see Wi-Fi, then you need to go to the router via the web interface and change the local IP in its settings, and specify the appropriate IP and channel.

A large number of subscribers who use mobile communications quite often ask questions about network problems, one of which is: “Why can’t my phone see WiFi?” Now it is impossible to imagine that any mobile device would remain without access to the Internet using this network. It is also natural that even at home users have a home WiFi network.

Why don't mobile devices see WiFi?

The WiFi network is now considered very convenient, accessible and mobile in almost all corners of the globe. She has many other advantages. For example, you can see quite significant savings on installation, deployment and expansion of the Internet. In addition, WiFi communication fully guarantees the compatibility of a number of equipment of different directions and many mobile users at the same time in the same coverage area. But, unfortunately, not all mobile device users have a chance to use this type of communication. And, of course, this begs the question: “Why doesn’t the phone see WiFi?”

Solving the Network Visibility Problem

Naturally, first you need to determine the reason why the phone stopped seeing home WiFi, that is, check whether there is a connection at all. To do this, you can perform simple manipulations, for example, see if there is a connection to WiFi from other types of mobile devices. You also need to reboot the adapter.

Possible reasons why the phone does not see WiFi may be as follows: the user's mobile device must have the appropriate equipment - a special chip. Also, a large number of users, surprisingly, do not know how to configure this network on their own.

To solve the problem of why the phone does not see WiFi, first you need to look at the settings of the router itself. Typically, a WiFi router automatically selects a given access point (channel). A large number of mobile phones begin to experience minor problems when this same channel is above 12. You should change the channel itself to a value from 1 to 9, reboot the device and try to connect to the network. Naturally, you shouldn’t forget about the settings of the mobile phone itself.

And if everything is configured correctly, you need to check the operation of the router and mobile device. You can also connect to a free access point somewhere to check. And if the phone sees the network, then most likely the WiFi problem lies in the home router.

Network connection problem for Lenovo phones

Very often, users of phones like Lenovo also experience network connection problems. There is a problem that the Lenovo phone does not see WiFi. The device itself provides the ability to work on channels from 1 to 11. Often the router is configured to a channel higher than 12, it turns out that there is incompatibility between the mobile device and the router. If changing the channel helps for other mobile devices, then Lenovo needs to perform other actions.

First you need to find the build.prop file on your phone and replace the line ro.wifi.channels with ro.wifi.channels=14. This manipulation can be performed directly on the computer in any text editor by transferring the original file via USB. After this, you need to restart both the phone and the router. After all these steps, the mobile device should see the network.

WiFi programs for your phone

In order to use all the capabilities of your mobile phone when connected to the network, you use numerous software. There is now a large selection of WiFi programs for your phone. Such applications are used to turn a mobile device into an access point to a WiFi network. The main thing is to choose good and inexpensive mobile Internet traffic, because, in principle, the mobile device will turn into a gateway between the 3G and Wi-Fi network. And this will allow the device to connect to the World Wide Web. Programs are divided by type of mobile phone platform, the most popular are Android, iOS, Windows Phone.

Android based WiFi programs: WiFi Tether and WiFi HotSpo

Nowadays, all multifunctional telephones used to access the network, social services or communicate on the Internet practically become unnecessary if the phone no longer sees WiFi. While solving this problem, many realized that WiFi Tether for Root Users is considered to be a very easy to use phone program. The only thing that it is not so popular with users is that it requires Root access rights, but this pays off with easily accessible functions and ease of use. By default, this program sets the WiFi point in open mode, connected without a password. Therefore, before using this program, you need to select an encryption protocol and specify the key to connect the network.

Another WiFi program for your phone is WiFi HotSpo. It is also easy to use, but it has much fewer functions than WiFi Tether, but when using this particular program, your mobile phone does not need to be “rooted” in advance. And what is attractive about this application is that it has such a function as USB Tethering. It allows you to use your phone as a wired modem when connected via USB to a computer.

iOS based WiFi programs

Unlike programs for the Android platform, similar utilities for iOS are not so common. But there is still a good WiFi program for an iOS phone, and that is MyWi. This application allows you to turn your mobile device into a modem. But for this to become possible, Apple devices must first be unlocked. The app has very good monitoring capabilities. And if suddenly the connection is not established, or it works with interference, MyWi has the ability to select another channel. Its only disadvantage is that it is paid.

Program for Windows Phone

In one of the first versions of phones based on the Windows Phone operating system, it was impossible to use tethering. But in subsequent models of mobile devices, this option was built into the system itself. It can be set to lock depending on what specific phone model is being used. The maximum connection to a network access point with active tethering is no more than five other mobile devices.

The problem of connecting mobile devices to the network and its solution

It is a very common opinion that quite soon the WiFi network may replace one of the available connections - mobile. But this raises one problem. It is still not possible to roam on a global scale. After all, this network currently has a small radius of action. And problems arise in the form that the phone does not connect to WiFi.

Nowadays, this network is already quite widespread everywhere. Developers such as Samsung, Zyxel, and Hitachi were among the first to produce phones with network support. Also, some time later, other manufacturers began to develop such phones.

Today, the communication standard is considered probably the most inexpensive, and many providers provide these services for free. But you don’t always have the opportunity to take advantage of a wireless network, and sometimes the question arises of what to do if your phone doesn’t connect to WiFi.

It happens that a mobile device sees the network itself, but does not want to connect to it. This especially often happens when the phone does not see home WiFi. If in public places where the network is provided, such problems have not arisen before, often the solution lies not in the phone itself, but in the home router and its settings.

When solving such a problem, it is not necessary to turn to professionals; you can fix everything yourself. To do this, you need to go to the device settings and change them. This can be done using any Internet browser. You need to dial the router's IP directly. These are the designations: 192.168.1.0 and 192.168.1.1. Next you need to find the DHCP section and check the Enabled section, in other sections - Default Gateway and Primary DNS - you need to enter the router's IP.

Thus, if all actions are performed correctly, then the issue should be resolved. This method helps protect data exchange, that is, it makes it possible to set a password for a network connection. Only those users who are allowed to connect to it will connect.

Wi-Fi has long been firmly established in the lives of mobile Internet users. One day a smartphone, tablet or laptop refuses to connect to the router - the owner of these devices will have to figure out why this happened and how to fix it.

The main reasons why the gadget does not see the Wi-Fi network

The smartphone or tablet does not see the Wi-Fi network because:

• the router lost power;
• the router itself has failed (physically, or “frozen”);
• Wi-Fi communication is not enabled (on a new device, or the router was previously used as a wired router);
• Wi-Fi connection is not enabled on your smartphone or tablet;
• glitches or viruses in the gadget’s operating system.
• The router does not broadcast the name of its network.

As you can see, the problem lies both in the router and in the gadget or PC itself. Both devices need to be checked.

Checking and reconfiguring the router

Often, checking the operation of a Wi-Fi network begins not with a PC or gadget, but with a router. The reason is the simultaneous loss of access to the Network on all devices connected to it.

How to restart the router

As an example - TP-Link routers.

Any router can be restarted by unplugging the power adapter for half a minute.

This is convenient - no need to turn off the power adapter

Some routers, such as those from TP-Link, have a power button on the back (not to be confused with a reset button in a tiny hole pressed with a paperclip or toothpick).

Reset router settings to factory defaults

Resetting the router allows you to roll back unwanted changes that you made out of ignorance, or (less often) due to viruses that got into the firmware or onto your PC/gadget.

Reset can also be performed using a button hidden from accidental pressing in a special hole.

Schematic placement of the reset button on most routers

Any point is required, for example, a paperclip bent at one end. After resetting the router, try connecting to your wireless network again, the Internet should work.

Optimizing router settings

Selecting settings that do not cause headaches when working on the Internet from any PC or gadget is a task within the capabilities of any user.

Checking your router's security settings

As an example, ZyXEL routers. Security is the first priority when setting up wireless, please do the following.

The router will restart, try connecting to your network.

Changing the Bandwidth

Changing the 2.4 GHz frequency band is an "act of desperation" when other settings have failed. But the user will pay for this by the fact that half of his (and neighboring) devices simply will not be able to connect. As an example, use the ZTE F660 router.

The Wi-Fi network settings (without encryption) in ZTE routers look impressive.

For example, the power of a Wi-Fi transmitter allows you to limit the coverage radius to one or two rooms - converting the percentage of the coverage radius into milliwatts delivered to the Wi-Fi antenna, we get 3–100 mW. For the percentages specified in the settings, the average coverage area in an apartment building or office building is valid. Specifying 10% will allow you not to create interference for your neighbors on the entrance/floor/street (“not flying” the signal of your router into your neighbor’s territory).

Comprehensive settings in the router can also be achieved in a “gray” way, by “filling” the OpenWRT (DD-WRT) firmware as firmware instead of the standard firmware - free software for routers from Chinese manufacturers.

OpenWRT allows, for example, to configure work with “exotic” models of 3G/4G modems that are not available in the standard firmware of D-Link, TP-Link and ZyXEL. You can also fine-tune how to bypass the tethering restrictions of Yota and other operators, integrate a torrent client and Tor encryption, and even connect an external drive without a PC/gadget to save downloaded content on it. This is achieved by installing additional scripts in the router’s flash memory that work with the main OpenWRT software - in contrast to the “native” firmware of the router, where such fraud is not provided for (“native” firmware is already assembled).

Checking Wi-Fi operation in Android smartphones and tablets

Despite the fact that tablets and smartphones, unlike PCs and laptops, where the Wi-Fi module is often removable/external, do not require complex diagnostics, the problem may lie in the gadget itself, and not just in the router and/or modems (if An ADSL/ONT modem or a 3G/4G USB modem works in conjunction with the router). This is true for the Apple iPhone/iPad/iPod/Watch, which will be discussed below, and for outdated gadgets based on Symbian, BlackberryOS, PalmOS and their other modern analogues.

Checking connection to a known network in Android

First, give the command “Settings - Wireless Networks” and check if the airplane mode is set - it blocks the operation of all radio transmitters of the gadget (with the exception of the GPS receiver).

Unlocked MTC-916 (ZTE Racer) and its Wi-Fi settings

Go to the Wi-Fi settings and select a network for which you know the key (for example, this is your ZTE MF90+ pocket router or similar). All routers (and gadgets/PCs operating in Wi-Fi dispenser mode) that you connected to are signed as known networks.

If there is no connection, the main reason is the wrong password for the Wi-Fi network, with which the gadget saved this network in the list of known ones. Give the command “Network information” (by clicking on the menu button under the visible part of the sensor) - “Delete”, then connect to the same network again.

Delete the settings for the router, then re-enter them

Another reason could be that the device itself freezes due to a virus or advertising code that overloads the processor and RAM in the gadget. Unlike the iPhone and other Apple gadgets, which are reliably protected from such sabotage, Android devices are reflashed precisely for this reason - if they freeze, any control is lost, including the submenu with Wi-Fi settings.

Restarting your Android device

If your Android smartphone or tablet is so frozen that it can no longer be controlled, and is not even able to restart its built-in Wi-Fi module, you can try to restart it from the power button by giving the “Restart” command. In the latest versions, if performance problems are detected, the Android operating system restarts automatically.

Try also calling a frozen smartphone. If the charge level before the freeze was low, wait until the battery is completely discharged, calling the frozen gadget again and again when the call tone passes - it happens that the 3G terminal in the smartphone receives calls and SMS, but the screen remains with a frozen backlight or is turned off. If the call fails (clicks and the response “Subscriber is unavailable” after one or more dialing attempts), remove the back cover, remove and insert the battery back, and turn on the smartphone. If your smartphone does not start, contact a service center or try to reflash the gadget yourself (if you are confident in your actions and have the necessary knowledge).

Reconfiguring an Android gadget

A new reconfiguration begins with resetting user data and OS settings. To avoid losing valuable files from the SD card, it is recommended to remove it. Depending on the gadget model, the microSD card slot is located next to the SIM cards and/or a hidden “Reset” button.

Disk C: (gadget flash memory) will be cleared (Android user folders).

It is possible that a complete reset of Android will remove Root access - gadget “administrator” privileges implemented by third-party applications such as KingRoot. In this case, you will lose full access to Android system processes, services, and hidden (including system libraries and drivers) folders and files. With a new setup, Root rights will need to be set again.

Now do the following.

1. Go to the already familiar Wi-Fi submenu and reconnect to any of the networks you know.
2. As soon as the Internet is available, go to Google Play and reinstall the applications that you previously used.

The Internet over Wi-Fi is indicated by attempts by background Android services to update pre-installed programs (these updates are enabled by default) and send some information about the gadget to Google.

Solving Wi-Fi problems on iPhone

The iOS operating system for iPhone, iPad, iPod and Apple Watch is almost completely similar. Everything that is said about the iPhone is also true for other Apple gadgets.

Restarting the Wi-Fi adapter in iOS

Apple's operating systems are very reliable and high-performance - the company is scrupulous about the performance of its gadgets and stops updating iOS on outdated models of mobile devices as soon as comprehensive checks show that these devices have exhausted themselves and will hang with the next iOS update. Thus, support for the iPhone 4s has been discontinued since August 2016 - the latest current version is 9.3.5 (“top ten” can only be installed using hacker methods). Therefore, settings, in particular Wi-Fi, should not freeze.

The connection should work.

Resetting network settings on iPhone

1. Give the command “Settings - General - Reset”.

   Choose to reset iPhone data and settings

2. Select Reset Network Settings.

   Select Reset Network Settings

3. Confirm deleting network data.

   Confirm the action by clicking the network information reset button

Information about operator settings, Wi-Fi networks and information about the iPhone configured for Internet distribution (access point mode) will be erased.

Restart, "break" iPhone

“Break”, or clearing the iPhone’s RAM, is done as follows.

1. Press and hold the iPhone's Power button until the software shutdown slider appears.
2. Release "Power" and press and hold the "Home" button (on iPhone models that have one) for a few seconds.

The shutdown screen will change back to the iOS desktop and the buffer (RAM) will be cleared. If you still have running applications, they will re-load the data on which your work has paused.

Restarting (excluding a “hard” reboot - short-term alternate pressing of the volume keys and holding down the “Power” button until the gadget screen goes dark) is turning off the iPhone (the “Turn off” option on the slider) and then turning it on.

Unfortunately, iOS does not have the “Restart” and “ReSpring” sliders (a safe mode without background and animations, launched only if you are jailbroken) - be content with what you have.

Other reasons for lack of Wi-Fi connection

The reasons for the lack of connection to the router are as follows.

1. The coverage area is too large - the device sees the router/hotspot/Wi-Fi base station, but cannot “reach” it itself. This can only be achieved by using a second router in repeater mode, with a directional antenna (usually homemade) directed towards the original repeater.
2. The owner changed the password/encryption and made the network closed/restricted. The old settings are now useless.
3. There is a connection, but the provider’s page appears with information about non-payment of the tariff, exhaustion of high-speed traffic, or the need to view advertising to gain access to the Network for so many minutes, hours or the whole day, or confirmation of low speed (if any).

If all else fails

The problem probably has hardware rather than software causes.

Malfunction of the router, USB modem or Wi-Fi module

Breakdown is different. This determines how repairable the device is.

1. Failure of microcircuits. One day the router turns off forever - for example, if it was located under a windowsill, and water from a flower pot spilled on it, shorting the outputs of the microcircuits.
2. Frequent overheating of the router: weak signals from connected devices and cellular networks, critical dustiness (the router is located in a dirty and unmaintained area of ​​the room).
3. Minor failure - drying out or explosion of one of the electrolytic capacitors on the printed circuit board; here it needs to be replaced, because the circuit diagram of the device is broken - it will not start, or will work unstably.
4. The router worked for many years, but recently it began to “glitch” and freeze - it was increasingly rebooted abnormally, and the flash memory “died”. Chinese equipment, especially cheap ones, ages and wears out faster than top models from well-known companies like Apple or Samsung.
5. Accidental breakdown of the router by static electricity when opening it, or from overvoltage in the network. It happens when the power grid is supplied not with 220 volts, but with an interphase voltage of 380, but such cases are vanishingly small.
6. Connecting the “wrong” power adapter to the router: instead of a 9-volt one, the user accidentally connects 19 volts (for example, from a laptop). In the best case, the stabilizer on the router board explodes, and if it is missing, the entire “signet” burns out.

If the router model is expensive, you can try to bring it back to life by taking it either to a computer or “gadget” service center, or to an uncertified repair shop for household appliances and electronics. USB modems and external Wi-Fi modules are much more difficult to repair due to their compactness and “jewelry” assembly.

Mobile device malfunction

Everything that was said above about routers is also true for gadgets and laptops, but there are differences. Thus, Apple technology, despite its “advanced” protection against various “Kulibins,” can be opened with a bang if step-by-step instructions are strictly followed. All that's left to do is to carefully handle the cables and remove the battery from the glue (if necessary, replace it).

Many tablets and smartphones with Android, especially at below-average prices, are even easier to understand. Apart from a few screws and primitive “hook” type locks, nothing holds the front and back parts of the case together, and the “signet” is generally placed on a large drop of glue and can be easily removed; The battery is generally removed in a second, like on Nokia smartphones of the 2000s. These are, for example, Archos tablets, ZTE and Huawei smartphones.

In the event of a breakdown of microcircuits (3G/4G/Bluetooth/Wi-Fi/GPS radio modules, CPU, RAM, flash memory, Lightning/microUSB interface), the motherboard is considered unusable, because, again, the thinnest assembly does not allow it “ rise from the ruins." Almost always a new gadget is bought - most often a previous iPhone model on sale, or a model with Android with similar technical characteristics. However, if the speakers, microphone, SIM and microSD sockets fail, the case is cracked, the sensor is broken, this component can be replaced. It is best to carry out all replacements of failed units and components at a service center.

In most cases, if you lose your Wi-Fi connection, you don’t need to run to the service center. Most often, problems are of a software nature, and even flashing the device should not scare you. Everything can be resolved.

If Android does not see the WiFi network, the first thing you need to do is understand which side the problem is on: on the device that distributes the wireless network (modem/router), or on your Android phone/tablet.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Determining the Source of the Problem

First of all, determine whether Android sees other Wi-Fi networks. Try sharing the network from a laptop, iPhone or other phone, go to a public place with free Wi-Fi.

If there are no problems detecting other points, the problem is clearly in the network, which . If the device does not catch any points, although other phones show their presence, then look for problems in the system and hardware.

Android doesn't see any Wi-Fi networks

If the device does not detect wireless points, although it previously saw them without problems, make sure that there are no errors in the system and that the module is working properly.

1. Open settings.
2. In the “Wireless Networks” field, slide the Wi-FI switch to the “On” position.
3. Start a network search.
4. Open advanced features and check “Always search for networks.”

In the settings of the latest versions of Android there is an option to reset network settings. Using it, you can fix system failures without resetting other device settings or deleting information from memory.

• Settings
• User and archiving
• Archive and reset
• Resetting network settings

If problems with connecting to Wi-Fi occur after updating or flashing the device, then you need to roll back to the latest stable version of Android. Use official or proven custom assemblies for firmware, then the question of what to do with the next system error will arise much less often.

The worst thing that can happen to a phone or tablet is hardware failure. If you suspect that the wireless module has failed, contact a service center to diagnose and replace the component.

Troubleshooting

Before you begin serious hardware diagnostics, follow a few simple steps:

1. Make sure that the network you want to connect to actually exists. To do this, see if other devices detect it.
2. Go to Android settings. Disable and enable Wi-Fi.
3. Reboot your phone/tablet.
4. Reboot your router if you have access to it. Unplug it, wait 10-20 seconds and plug it back in.
5. Bring the device closer to the router. The signal may be blocked by obstacles or the distance is too great.
6. Check your saved password again. If you changed the password in the router settings, it could be saved in the connection settings on Android.

That's all you can do on your Android device. If after performing these steps the network does not appear, proceed to checking and setting up the signal source.

Setting up the router
