I have a Dell Inspiron N4110 windows 7, and the wifi box in the bottom of the screen has a red line through it and will not pick up my wifi unless i directly hook it up to the ethernet cable from my modem. It happened one day out of the blue and I cant fix it. I NEED my laptop to be portable, PLEASE HELP!!!!! Also, I turned the wifi on and off, doesnt help. Thanks!
