i have the above laptop, the other day i was working on it and its wireless just stopped working. it was fine when i started up, i loaded a few pages, then it said i was connected but no internet access, then it simply said no networks could be found (while another comp and my iphone were still working fine on our wireless). same thing when i rebooted, so now im limited to a few feet from the router which defeats the purpose of having a laptop for college. system restore didnt help, any ideas?
