Acer Swift SF113-31 does not detect home wifi

My laptop does not detect my home wifi. All other devices are able to connect to it and it can detect and connect normally to some other wifi's like the hotspot from my phone.

From this laptop I can only detect 3 wifi connections, while with my phone or other laptop I detect 8, so there is some kind of blind spot regarding wifi detection on this laptop.
If I compare the details of the undetected home wifi and the working phone hotspot connection they both use Wifi 4 (802.11n) with same security (WPA2-Personal) and same Frequency (2,4 GHz) so I find no reason for my laptop not to detect both of them normally.

I have the most recent driver for the wireless adapter installed, i tried changing the wifi channel, i tried manually connecting to the wifi, i tried with netsh winsock reset and a few other commands i found on this forum, and i tried resetting the router after leaving it down a few minutes. 

I'd gladly do all of this again in some specific order if someone thinks it will work

    Your SF113-31 has a WiFi 82.11a/b/g/n/ac card in it, so should be able to see most any network out there. Are the three that do show up the thee most powerful signals? It might be that the antenna cables have come loose inside. If it were something corrupted in the driver, breaking WPA2 for instance), then you would still see the full range of available hotspots.

    The most powerful signal on my other device (positioned right next to the SF113-31) is my undetected home wifi, then my detected phone hotspot. Then one of my neighbours detected wifis, then an undetected one, then the last detected wifi, then some undetected ones. So the strongest signal doesn't show up and only a few of the moderate-strenght ones do.

    Are they all 2.4GHz or is it a mix of the 2.4GHz and 5GHz? I'm still wondering if you have an antenna disconnected. I believe each radio has it's own antenna internally, so there are two.

    I have two SF113-31s. Neither one will see the wifi connections for my new TP-Link AX50 router. The router is set to b/g/n/ax mixed. I tried updating wifi drivers on one of them but no effect.

    SOLVED: b/g/n/ax mode is not detected by the Swift. If I change it to b/g/n it works. That is lame but no choice for the moment.

    Does the router not do 802.11ac? Ah, I see in their specs the router only does ac on the 5GHz bands. That's pretty bogus... :(
