What should I do if the laptop tower is not turned on and can t find wifi 100

Find the wireless network in the control panel, and it will be powered on.

Is there a problem with the laptop network card? Or the NIC driver is not installed properly.

Cause 1: The wireless channel automatically selected by the router interferes severely.

Solution: Log in to the router background to modify the channel of the wireless network.

Note: If you have another computer, you can use another computer to log in to the background of the wireless router, and if you don't have another computer, you can also use your mobile phone.

Here we take the TP-Link router as an example to modify the wireless channel, basically all routers support it, but the background interface of different brands of routers is different. The background address of the tp-link router is yes, and if the background and password are not changed, the default background and password are admin.

After entering the router management background, we click on the routing settings > wireless settings to avoid the interference and overlap of unlimited signals, it is recommended to set the wireless channel to or other channels (1-13 numbers can be tried), I set it here is 1, click Save.

We'd better restart the notebook, and then test whether it can be connected to your own wireless network signal, if 1 wireless channel doesn't work, try other channels, such as wireless network channels, basically modify the channel, have helped many people solve this problem. If not, then it may be caused by the difference between the wireless network card of the computer and the wireless channel setting of the router.

Cause. 2. The wireless channel setting interval of the wireless network card and the router is different.

If you can't log in to the router background, you can also try this.

This problem is basically caused by the router setting 12 or 13 wireless channels, but the wireless channel setting interval of the wireless network card is not within the range value. Take win10 system as an example, we right-click "This computer" and select "Manage", in computer management, we click "Device Manager", network adapter, find and right-click on the wireless network card device of your computer, and right-click to select "Properties".

In the property interface of the wireless network card, switch to the "Advanced" tab, select the "country region" in the attribute list, the value on the right is the wireless channel range value, for example, the router is set to 13 wireless channels, we set 1-11 wireless signals are definitely not in the range, we set it to 1-13 channels, click OK.

The above is the solution to the solution that the laptop shared by the installation home can not find your own wifi wireless network signal, and you can't find your own router signal, but other people's homes can be searched, and the mobile phone can also be connected to the wireless network output of the router normally, then it is very likely to be the problem of router channel interference, we only need to try other channels to solve the problem.

<> can give it a try with network repair.

Question: I had wifi the day before yesterday, and then the network signal was cut off, and it was restored after 1008. The phone solved, but the laptop's wifi was gone.

You restart the router and plug it in with a network cable to see if the laptop can be used.

The question, I asked the person in charge of computer management of the property, but it was not solved.

I asked the person in charge of computer management of the property and didn't solve it.

If it worked before, you can try to restore your computer if you have a backup before.

Question: I tried to restore it to September 29th, but it didn't work.

Is there an earlier date? Because if it's too close, it proves to be no different from the most recent.

Question: Because it can be used on September 30th.

Then you can check the problem on your router. Let's see if there are any permissions for the device and the like.

Basic computer, if you can't find the wifi signal, you have to see if your wifi signal is turned on, and then your home wifi is not turned on, and then connect, if it is really not contacted, you can turn off the computer and restart it, and then try to connect, or the router to reconnect.

The laptop can't find the wifi signal, so maybe it's a router? If the signal cannot be sent if it is damaged, or the network at home is disconnected. Or a notebook. The Wi-Fi card is broken.

It should be that your computer is not connected to the wireless network, or it itself has poor signal reception.

Either there is no public network nearby for the computer to find, I hope my answer can help you.
