Laptop does not display our WLAN?

My laptop does not connect to our WLAN. My cell phone and the devices of my roommate show it and are connected, only mine is reluctant. He shows all the other available networks, just not ours… I also tried to install some drivers (according to the internet), but he still refuses to let me know our WLAN at all

Maybe it's because there's radio in different networks or receiving.

If e.g. The laptop can only see 2.4 GHz and the router sends in 5 GHz, then you see nothing.

Installing any drivers is totally wrong. You need to install the right drivers, just for your laptop Wi-Fi. Driver download always make on the manufacturer side of the laptop.

Check the product data for the laptop if the built-in WLAN card of the laptop supports 5 GHz WLAN (ac standard). Because if the router is working at 5 GHz (automatic channel selection of the router) and the laptop 5 GHz can't, he "does not see" your wireless network. Then set a fixed Wi-Fi channel on the configuration page of the router (in Advanced View, Expert Mode). Good 2.4 GHz (overlap-free) n channels are 1, 6 and 11.

Some US devices can't receive Wi-Fi channel 12 and 13. Can it look in the router (configuration page in the browser), which wireless channel he uses.

Or determine the channel used with the free Android App Fritz App WLAN.

If he shows networks at all, it is probably a working driver…

Possibly. Is the wireless router set so that it works on channels that the laptop can't…

Just a little cheaper devices (but also older) can't use the 5GHz band - so the new router so synonymous usually synonymous with both bands operated simultaneously (2.4 and 5GHz). Of course, if someone has come up with the idea to turn off 2.4, that explains.
