I did back it up. I upgraded from win 7 home 32 bit, to win 7 pro 64 bit. And as you know the software network adapters are NOT compatible. This is the first and only time Ive ever used a forum. Since I cant get an intelligent answer I'll go ahead and buy a Netgear Wireless USB Desktop adaptor for $19.95 then return it. Been to HP Support, Gigabyte Support and AMD Support.......All to no avail. thnx anyway
