I recently bought a refurbished ASUS U56E-LB7 and when I received it everything was working fine though it was a bit sluggish due to all the bloatware. What I normally do when I buy a new laptop is do a clean installation of Windows 7 and then download all the drivers. Well after formatting the drive and installing Windows 7 everything works except for Wifi. There's a big X on the wireless LAN icon in the system tray and when I go to device manager I don't see my wireless adapter under Network Adapter. I can connect to the internet via an ethernet cable, it is only wifi that doesn't work.

I've tried downloading the wireless drivers from the ASUS website for my model but nothing works. The installation stops halfway and I get a message saying "The Device may not be present or could have been ejected/unplugged from the system. Insert or Reinsert Now."

I know for a fact that the wifi was working fine when I first got the laptop. This problem started occurring after I reformatted and reinstalled Windows 7.

I've tried googling this problem but haven't been able to find a definitive solution. Tech support was next to useless as well. I don't have recovery disks either because it was refurbished and, quite frankly, I've never encountered this problem with my previous laptops and so I was not expecting this to happen.

Any ideas?

Thanks
