Even if you were using Wi-Fi for the download it's probably just coincidence that something happened to the adapter immediately after the download completed. Do I have that right--that the download did complete?
Since you just downloaded Windows 7--I hope a genuine, not pirated, version--why are you trying to troubleshoot the adapter problem now instead of after a re-install of the OS?
