Since a couple of weeks now, my wlan has stopped working. Everything seems like before, it just doesn't find any networks anymore. Im now fairly sure that this is a hardware problem, because I didnt change anything, i just bootet up and it didnt work. Also i reinstalled my system a couple of times since now (Win 7, Win 8 and Archlinux) and every System recognized the Wlan card without a problem, but no Networks.

My Question is now: Where exactly is the problem? obviously i want to fix it, and im not sure what to do. I could buy a new WLan card and try it, but it could be, that the card is working and the antenna has some sort of Problem. Can i even fix that if its the antenna? It runs AFAIK around the Laptop screen for best reception. The laptop is some sort of noname Laptop, with a noname standard-case, so it could be exchangeable

The weird thing: sometimes (maybe 1 out of 50 boots) the wlan works for ~10 minutes. I noticed that the WLAN-LED indicator is still correct (mostly off, except for those short periods when the Wlan is actually working)

Did anyone experience this sort of problem? any advice?

did you end up solving this problem else we might as well close it – Ivo Flipse Jul 14 '12 at 12:56

Do you have a WLAN hardware switch that might be in the off (red) position?

Well yes, i have one, but this was the first thing i tried. The switch works though, because when the wlan works (those mentioned few times) i can shut it down with the switch. – Simiil Mar 23 '12 at 10:01
