I have wireless internet that I use for 4 laptops for a long time now, 3 days ago, and all of a sudden I can only have wireless internet connection at one laptop at a time, so I have to turn off the 1st laptop with wireless connection and restart the 2nd laptop to get wireless connection. I cant have 2 or more laptops with wireless connection at the same time and this started as I said only 3 days ago and just an FYI I did not install or download anything. PLEASE help.
