I had to buy a new hard drive for my D620 and installed a generic D620 build onto it. Everything seems to be working except the WiFi. As soon as windows boots up it gives a dong noise and a x appears over the little wifi symbol in quick launch. Double clicking on the symbol gives a message box reading the following: To me this meant that the driver is not installed. But I cannot find the wireless adapter in Device Manager Any idea what has gone wrong here? I had assumed the Wireless card was built in and there were no other drivers. I have then gone onto install as many drivers as I could from the dell support site. They install fine but i still have 'no adapter' issue. PLEASE HELP!!
