PC does not recognize WLAN network?

My problem is the following: For some time now my laptop no longer recognizes our WLAN, my cell phone and other tablets, PC's, etc. Can connect without any problems, while with my laptop the network does not even appear on the list of available networks, but that of Neighbours. In addition, I can connect to the hotspot of my cell phone and so to the Internet.

In addition, the "detection" of our WLAN worked on Thursday, but no longer on Friday…

But what is it now? The WLAN seems to work otherwise, the WLAN module of the PC apparently also…

Check drivers. Otherwise change channel in the router

I also had you have to take the router out of the power cord for 30 seconds and put it back in then it should work again

Times your router restarted?

First action: restart the Wi-Fi router.

Yes, several times, did nothing.

I have at least 5 times in two days…

Thanks, I'll try!

Is WLAN n active with 2.4 GHz?

Yes, but all devices are on the 5 GHz network. I will try to switch the laptop to the 2.4 GHz network or another device…

Second action: start troubleshooting the computer
