I just bought a new packard bell netbook Model As I first turned it on, it had windows xp installed on it where everything worked including the wireless. Then I upgraded it to windows 7, after which the wireless didn't seem to work at all. First it didnt have any drivers for the device, so I downloaded the windows 7 driver for Wirelss LAN Atheros HB95 on packard bell's site. Now it has installed the drivers successfully, but it says "no connections are available" when i search for a network. There is no wireless switch on this laptop, so there is no way to turn it off. Strangely, wireless works when I plug in a d-link wireless adapter. So my netbook cant find any wiress connections from the built in wireless adapter, but can from the dlink adapter, How do I fix this?
