I am having problems keeping my wireless active. I have Linksys N router and use Intel(R) ProSet wireless to connect with. Most of the time my link has either dissapeared or message comes up that there is a problem with my profile. I have tried going to Dell, Linksys support and recieved tempoary fixes, but nothing stays. I have also taken this laptop to Geek Squad and they say there is nothing wrong, it connects to the store router with no problems. I can connect to other wireless sites in my area, just not mine. This is really getting the best of me and I would appreciate all the help I can get.
