I never had to deactive my card in BIOS, haven't touched BIOS for a while, but I did switch the key on my laptop on and off a couple of times. I've done that with every attempt and verified that from the hardware side everything was on. Sadly, it was, but the light still didn't come on.
I think the WLAN card might be fried. I can't imagine how it could have happened, but after having done standard procedure to get everything going I have a hard time believing that it's SUSE's fault, especially since I managed to get SUSE online and running on a similar computer with no problems and it'd worked flawlessly in 11.3.
I think that because I've now tried installing Kubuntu und Ubuntu on it, and also tried running various live systems on it. They recognize the card, recognize the required drivers - Ubuntu & co. even asked me if I wanted to install them automatically - but even when they're installed they don't work. I've had Ubuntu 10.10 running on it as a live system before and it was able to get into the Internet, so the problem really seems to be hardware based.
So now I'm going to order a new network card and try swapping it out, seeing if that helps.
As a quick side question, does anyone have any suggestions as to what card I should order? I was thinking maybe a Netgear one, they seem to be pretty nice.
I'll let you all know as soon as I've tested whether it was just the hardware or not
