Why can t the wifi computer found on the mobile phone find 30?

There are many reasons why your computer can't find a wifi signal, but the most common ones are as follows:

The wifi function is disabled on the laptop. Solution: FN+F2 (or any other security check on your laptop with a wifi logo on it).

The wireless network card driver of the notebook needs to be upgraded, the solution: connect to the wired network, update the wireless network card driver or copy the latest wireless network card driver from other computers and install it on the notebook.

Another reason is that there is too much wifi in the current area, and some wifi cannot be found, so the way is to open the network and sharing center and set up a new wireless network.

First of all, there is no distance between the wireless router and the computer, if it is a problem with the router: then the mobile phone can search for signals and use it, and the computer sometimes finds it and sometimes can't. If it's a problem with the computer, then it can search for other wireless signals every time, but not at home.

Added: The mobile phone can be searched every time, and the computer will sometimes not be searchable and needs to be restarted to connect.

It's the same with my computer, and I just found a solution. Go to the wireless router settings and change the channel to 11 in it. In general, the router is set to automatic, and the computer defaults to 0-11. So sometimes you can find it, sometimes you can't.

First of all, confirm whether your computer has a wireless network card, built-in or external, and then confirm that your wireless network card driver has been installed correctly, and thirdly, it is to configure it after the correct installation, check it yourself.

From your description, you know that you can search for signals, but you can't. Whether all of them can't be searched or only users can't be searched.

When you can't find it, there is no wifi sign at all in the lower right corner of the computer. See the main scseaner. Only this one can't be searched, it can only mean that your receiving ability is weaker than the others.

It's OK to buy an unlimited router at home! The main thing is that you have broadband and community fiber at home! As a result, the computer cannot find the wireless. If you have wireless at home, it means that the computer doesn't have a wireless drive, or the drive isn't running. Check it out.

The computer lacks a wireless connection.

The reasons why the computer can't find wifi but the phone can:

1. The router may have set up a wireless channel that is not supported by the deviceSome laptops, TV boxes, and smart TV wireless network cards may not support the frequency band, or there is wireless signal interference and overlap, and the channel of the wireless network needs to be modified in the background of the router.

2. The wireless channel setting interval of the wireless network card and the router is different, if it is a laptop or a desktop equipped with a wireless network card, we can also set the channel interval for the computer, for example, the router is set up with 12 or 13 wireless channels, and the wireless channel setting interval of the computer's wireless network card is not in the range of Labusui value.

3. The network needs to be repaired and solved by third-party software. For example, there is a network repair in the toolbox of Tencent PC Manager, and you can directly click on the tool to try to fix the hole. Click Network Repair, after a period of time, it will automatically fix the network problems, if it cannot be repaired successfully, it will explain which error type is the cause.

Solution: The laptop is connected with a wired network card first, or the mobile phone logs in to the router background, here we take the TP-Link router as an example, and other brands of routers can be referenced.

The background address of the tp-link router is yes, the default background and password are admin (if you modify yourself, you should know), the background address of each brand router is different, you can see that the nameplate on the back of the wireless router almost has the background address and account name and password of the login.

After entering the router management background, click Routing Settings, Wireless Settings, find the wireless channel settings, please set 1-11 channels, it is recommended to set or 11 channels.

After setting up the wireless signal of the router, we use a laptop or other device to connect to the wireless network signal, if the wireless channel 1 is not working, try another channel. The old smart TV of the Android system at home before is,The router is set up13Wireless channel,The wireless network can't even be searched,Replace the 1-11 wireless signal can be searched。 <>
