It Works! OMG, I got back from Best Buy (Worst Buy) an hour ago with my new Cisco wireless adapter, because my WNDA3100 wasn't recognized by Windows 7 64 bit. Well, the Cisco wasn't recognized either! So I found THIS forum and did what the dude said, and Blammo! My WNDA3100 works full speed with Windows 7 64 bit.
Thank you SO much. On my way back to Worst Buy to return the Cisco adapter.
Thanks again :D :D :D
