Here what i seeWe're more of an Android site here, but I support Windows at work..
It sounds like you need to find the driver for the wireless adapter. If you look in Device Manager, do you see the wireless card listed? Do you see an unidentified device and no wireless card?
Help me plzYup - that network controller under other devices is likely your wireless card since I don't see it listed in the network adapters section. You'll need to track down the driver for that component and get it installed.
