If you went to this page, then most likely your phone has stopped seeing the Wi-Fi network, or networks. This can be a home network, somewhere on a visit, 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 fail to 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 perfectly 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, first it is advisable to find out what the problem is: in a mobile phone, or a Wi-Fi router. 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 you will be able to do something.
Basically, it doesn't really matter which device you have the problem on. It is clear that this is most likely an Android or iOS phone. Well, maybe Windows Mobile too. Since this problem can hardly be solved in the settings of the mobile device itself, it does not matter what device you have. It's the same with the router.
Note! We will consider the problem when the phone does not see at all the Wi-Fi network we need, or not a single network. Not when there is a problem with the connection, or access to the Internet after connecting. If you have a problem with connecting / accessing the Internet, then read the article The phone does not connect to Wi-Fi. Internet does not work.
I have already written separate articles on Android and iOS devices:
- What to do if iPhone or iPad does not see Wi-Fi
- Android tablet or smartphone does not see Wi-Fi
In this article, I will provide general guidelines that should help you.
The phone does not see the Wi-Fi router: possible reasons
If you have a problem with a Wi-Fi network at 5 GHz, then check out this article: https://help-wifi.com/poleznoe-i-interesnoe/pochemu-noutbuk-smartfon-ili-planshet-ne-vidit-wi -fi-set-5-ghz /
1Disable / enable Wi-Fi, restart your phone and router. To get started, just go to your phone's settings and turn off Wi-Fi. I think everyone knows how to do it.
Then turn it back on.
We reboot the phone:
- In Android, just press and hold the power button, then select "Restart". Depending on the manufacturer and Android version, the steps may differ slightly.
- On the iPhone, you need to hold and hold the Home button and the Power button. The phone will restart.
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 found here.
2We determine what is the reason.Check all three points:
- If your phone does not see any Wi-Fi networks, but they do exist and other devices find them, then it is clear that the problem is specifically in your smartphone. All I can advise is to restart it and remove the cover from it. If he is. If that doesn't work, you can try performing a full factory reset. If this does not help, then you will have to carry the device to the service center.
- When the device does not find one network, the first thing to do is to check if other devices can see it. If they don't see it, then most likely the problem is on the side of the router. First, reload it. If this does not help, then see the article: the router does not distribute the Internet via Wi-Fi.
- If other devices find a Wi-Fi network, but your phone does not, but at the same time sees other networks, then most likely the problem is in the router settings. Changing the wireless channel and region usually helps. Below I will discuss this in more detail.
You need to go to the settings of your router, go to the section with the Wi-Fi settings, and try to set the static channel of the wireless network and another region. You can also set the channel width to 20 MHz. Better take turns.
On TP-Link routers, it looks like this:
For more details, see the article: how to find a free Wi-Fi channel and change the channel on the router. You can experiment with channel and region. For example, put the US region. If you have set a static channel in the settings, then set "Auto".
Other problems with Wi-Fi network detection
I also noticed that people often write that the phone does not see the Wi-Fi of the laptop. I understand that the problem occurs when distributing the Internet from a laptop or PC. In this case, my advice is to make sure the laptop is broadcasting a wireless network first. For example, look from other devices. You may have started the access point incorrectly. Here, an article on how to distribute Wi-Fi from a laptop or computer without a router will come in handy. Bring your phone closer to your computer.
The next case when Wi-Fi problems appear after phone repair. For example, after replacing the battery, screen, glass, case, 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, there is no need to exclude hardware failure. Everything breaks down, 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. I am always glad to answer your questions and grateful for the additions to the article.
