I have had my laptop for a couple of years. It has worked great until a couple of days ago. I have been running wireless internet on it. I used it one day just fine. The next day when I logged on, my printers are gone, my internet connection is gone. When I try to pull up or search for an internet connection, it says it can't be found. My desk top is also wireless and that one works just fine. I have run virus scans and they have come up with nothing. Please help.
