"Why does my wifi signal keep dropping?"に関する回答I'm a technician and I noticed this as well. AFTER the wifi card overheats, due to excessive gaming/video streaming, the wifi card has overheated and has not been the same since. It will stop connecting, but I would have to "turn wifi off" for a few minutes and turn it back on and it will work. I don't think the wifi cards are replaceable though... still looking for an answer to that.
