For a short time I have the problem at home that two out of three computers at my house and one out of two playstations do not find the WLAN. The problem came up all of a sudden, although nobody changed anything about it.
Of course, we have already started and changed everything several times. So far, I have not been able to find anything helpful on the internet because I seem to be the first person in the world to have this problem.
Does anyone know what could be going on there?
Yes I can. It may be that the Wi-Fi is sent over 5ghz, for example, and some WLAN modules can't receive that.
May well be on the frequency band and / or radio channel.
Probably your router is flat.
Take your phone and turn on the hotspot, find your devices all the hotspot, it is on the router… Then maybe put it back.
