I have an Asus k50i laptop. It used to work just fine when I got it. The last time I used it. The wifi receiver stopped working. I've tried the f2 key mutiple times. I've even had to completely factory reset it more than a few times and that usually fixes the problem. Now Everytime I try and troubleshoot the connection. All it tells me is " a network cable is not properly plugged in or may be broken" I've used an Ethernet cable on it and that works just fine. Really want to know what I can do to fix the problem. Could I reinstall Windows or do I need to have it taken apart and looked at?
