Holysmoke - i'm having the same exact problem. However, this has occurred
because i upgraded my home wireless network to a new belkin wireless N
router. I set up the WEP encyrption and got all of my PCs seeing and using
the router again. All of the PCs use USB adapters to connect to the router -
and I could easily connect and put in the WEP encryption key to use.
However, I tried connecting my Vista based laptop, and it sees the network
fine, but when i try to connect, it wants a username, password, and logon
domain. I never set up any sort of username or password for my router - just
the 128WEP key. What do i put in these fields to get my vista laptop talking
to my new router?

Upton - were you able to find out the problem?
