Hi, my wife's laptop has been used for several years without this problem. We have 4 computers, 3 of which are connected to the internet via wireless connection. The computer is a Dell Inspiron 2200. Yesterday morning it worked as always, however, yesterday afternoon it would not (and still does not) connect but the other two laptops work just fine. I get a message saying that there is hardware unplugged. No change in programs or drivers recently. Ideas?
