If you have landed on this page, then most likely your phone has stopped seeing wifi network, or networks. It could be home network, somewhere away, a public wireless network, etc. The problem is that the network we need does not appear in the list of available ones on the phone. He simply does not find it, does not see it, and, accordingly, it is impossible to connect to such a network. It is not uncommon for a mobile device to not find a specific Wi-Fi network. Which, for example, a laptop sees and connects without problems. Or it may be that the phone does not find any network, but other devices see them and work fine with them.
In this article, I will try to collect all the most popular causes and solutions that can help you solve this problem. As usual, it is advisable to first find out what the problem is: in mobile phone, or wifi router e. If the problem is with the Wi-Fi network at home, then we have a better chance of fixing everything, since we have access to the router itself. If this is someone else's network, then it is unlikely that something will be done.
In fact, it doesn't make much difference on which device you have a problem. It is clear that this is most likely an Android or iOS phone. Well maybe more Windows Mobile. Since in the settings itself mobile device this problem can hardly be solved, it does not matter what device you have. It's the same with a router.
I have already written separate articles on Android and iOS devices:
Then turn it back on.
Reboot the phone:
We reboot the router. If you have access to it. It is enough to turn off the power for a minute and turn on the router again. You can perform multiple reboots in a row. More details can be read.
2 We determine what is the reason.Check all three items:
You need to go to the settings of your router, go to the section with Wi-Fi settings, and try to set a static wireless network channel and another region. You can also set the channel width to 20 MHz. It's better to take turns.
On TP-Link routers it looks like this:
More details in the article:. You can experiment with the channel and region. For example, put the region USA. If you have a static channel set in your settings, then set it to "Auto".
I also noticed that people often write that they do not see the phone laptop wifi. I understand that the problem occurs when distributing the Internet from a laptop or PC. In this case, I advise you to first make sure that the laptop is distributing a wireless network. For example, view from other devices. You may have started the hotspot incorrectly. This is where the article comes in handy. Bring your phone closer to your computer.
The next case when problems with Wi-Fi appear after phone repair. For example, after replacing the battery, screen, glass, housing, etc. In such cases, I advise you to immediately take the phone to the workshop where it was repaired. Since the master most likely did not connect the antenna, or the Wi-Fi module itself.
Well, you don't need to rule out a hardware failure. Everything breaks, and the module that is responsible for connecting to Wi-Fi is no exception.
As usual, you can leave your question in the comments, or share useful information on this topic. Always glad to answer your questions and grateful for the additions to the article.
If Android does not see WiFi network, the first step is to understand on which side the problem arose: 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 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.
Attention! You can ask your question to a specialist at the end of the article.
The first step is to determine if Android sees other Wi-Fi networks. Try to distribute the network from a laptop, iPhone or other phone, go to a public place with free Wi-Fi.
If there were no problems with finding other points, there is definitely a problem 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 the hardware component.
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.
In settings latest versions Android has an option to reset network settings. With it, you can fix system failures without resetting other device settings and without deleting information from memory.
If you have problems connecting to Wi-Fi after updating or flashing the device, then you need to roll back to the last stable working android version. Use official or verified custom builds for firmware, then the question is what to do with the next system error, will occur much less frequently.
The worst thing that can happen to a phone or tablet is hardware failure. If you suspect that a module wireless communication out of order, contact the service center for diagnostics and replacement of the component.
Before you start serious hardware diagnostics, follow a few simple steps:
That's all you can do on an Android device. If after performing these steps the network does not appear, proceed to check and configure the signal source.
If you have access to the router, then check its settings. What can help:
Router settings are different, but all have a Wi-Fi section. See again how to set up Wi-Fi on specific model router and make sure you have the correct settings.
Increase If when you try to establish a connection, the inscription “ ” appears, but nothing happens further, try:
These methods are also relevant for other devices from which Wi-Fi is distributed. If you are using third-party software to create a wireless connection from a laptop or phone, make sure the mobile hotspot is set up correctly. Try to connect to it from another phone, and if it is impossible to establish a connection, create a new point.
A wireless Internet connection has many advantages, but it is often the case that a laptop does not see a Wi-Fi network. To start troubleshooting, you first need to figure out what exactly is happening. Sometimes the laptop "refuses" to see any specific connection point, in other cases the device cannot connect to any wireless network at all.
The most common situation is when the laptop does not find any point at all WiFi access. In this case, the following conditions are met:
To understand why this is happening and deal with the problem, you first need to try to manually enable the network adapter. Depending on the operating system, this is done in the following ways.
For windows 7 the sequence looks like this:
If you have windows computer 8, then the activity check is done through the PC Settings section, which is located in the Control Panel. In it, select the item Wireless and move the slider to the "Enabled" position.
In windows XP, the adapter usually does not need to be turned on manually. If this is still necessary, then this is done in the same way as in windows 7 or through the icon on the taskbar.
The same can be done through Device Manager − Network adapters.
Whatever the operating system, if a yellow triangle is lit next to the adapter icon with exclamation mark, this means that either the adapter is not active, or the wrong version of the driver is installed for it. If the device does not show a connection due to the driver, then you should download the correct version that is suitable for your laptop.
Network access can be disabled on the laptop itself using a keyboard shortcut or a special switch on the case. How to make the device connect to the Internet? You must again press the same combination.
For different models laptops, this action is performed using various key combinations: "FN + F2", "FN + F12", "FN + F3", "FN + F9". These combinations help to turn off the network, for example, before an air flight - this option is called "On the plane" and is available on all modern mobile devices.
Also, sometimes you may find that the laptop has stopped seeing the Internet after it has been cleaned of dust inside. If this happened, it is likely that during the cleaning process you accidentally turned off the wireless module or disconnected the wires somewhere. In this case, the laptop does not even look for a network. To fix the problem, you will need to reconnect the adapter, and if this does not help, replace it with a new one.
Now consider another case, namely, when there is one point wifi access, which is seen by the phone, netbook and other devices, but the laptop does not catch it. In such a situation, the sequence of actions looks like this:
Another common reason that a device ignores a certain network or does not see access points at all, including on windows 10, may be the presence of virus software in the system. In this case, you need to scan your PC for viruses and remove them.
The “culprit” of the fact that the PC does not find the network may be itself wifi router. What to do in this case?
Whatever problem caused the laptop not to see the wireless network, it can be solved by any of the listed methods. In the beginning, in any case, it is worth installing the latest drivers and checking if the wifi module is functioning normally.
Video - what to do in such a situation?
To prevent such problems from returning in the future, it is worth periodically installing fresh versions software to your laptop or netbook. This can be done both manually and using special programs.
Many users who switched to the eight from earlier Windows versions, faced with the problem of detecting their own Wi-Fi network. The problem exists and it was even covered on the official Microsoft website. If your wireless adapter sees all other networks except the one you need, then read the text below. Restoring performance is no more difficult than installing a trunk on your SUV. Excellent FastClick installation technology, which is used on the Thule Touring 200 model. This is a patented fastening system with special handles, thanks to which the operation can be done with one hand.
If you are using USB WiFi adapter on another PC, then the first step is to reinstall it. Remove from the system and reinstall.
Check the driver wireless adapter on the eight. If you just installed Windows 8, then the driver may not work correctly. You can do this through device Manager. To enter it, move the cursor all the way to the right so that an additional menu appears. Choose there Search. And already in search line dial device Manager. We are looking for a line in it "Network adapters" and carefully check that they are all working (no exclamation points). You can try turning the adapter on and off ( right click mice):
Right click on the wireless adapter and select "Disable", then click again and select "Turn on"
You need to change the channel on which the Wi-Fi broadcasts. How to do it? If you have a router / modem, then you need to go to the settings through the web interface (in the browser, type 192.168.1.1 or 192.168.0.1 - depending on the model). We are looking for wifi settings(in Russian they write "Wireless Network". There we look for the line "Channel" or "Wireless Channel":
It is better to set either the FIRST or THIRD channel:
Check if the wireless standards on the modem and on the computer match!. Wireless network standards are 802.11a, 802.11b and 802.11g and 802.11n. The latest and most modern of them is compatible with all the previous ones, but not vice versa. Those. if your adapter on the eight works in 802.11g mode, and the modem is 802.11n, then you will not be able to connect.
HOW TO CHECK WHAT STANDARD IS ON THE MODEM AND ADAPTER IN THE COMPUTER?
ON MODEM: We go to the settings through the browser at 192.168.1.1 (192.168.0.1 - depending on the model). All routers / modems have such a category as "Device Information" or "Device Info". There is usually information about WiFi connection, where the standard is indicated:
ON LAPTOP: Often, the Wi-Fi standard is written on the laptop itself (on a sticker that lists the characteristics of the machine). You can Google the name of your laptop and see the specifications on the manufacturer's website. Here is an example of a Sony Vaio with the specifications listed on the sony.ru website:
Also, the standard of your adapter can be viewed using the program Everest.
