Worked great for almost two years not it simply doesn't.
It's the Broadcom 802.11 WiFi adapter... It disappears. I tried removing it and restarting, doesn't work. He'll I can't do that always because it simply isn't there at times and when it is it doesn't connect to the internet. If I try the problem resolving thing when it doesn't work it simply makes it disappears and tells me to connect a cable... I also tried to use an external WiFi adapter but it simply rejected it.
If you need anymore information just tell me because I really have exhausted my "Computing" knowledge.
