I upgraded my home wireless network to a new belkin wireless N
router from a belkin wireless G 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, When I tried connecting my Vista based
laptop, 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?

Any thoughts would be great.
