Now click on the Wireless Networks tab and select the network in the list at the bottom.
I recently bought a new Linksys wireless router and after setting it up with basic WEP security, I tried to logon from my laptop and was successful! So then I tried to connect from my desktop computer that has a wireless USB adapter attached to it and I ended up getting this error message: Fabulous! I checked my settings on the wireless router to make sure I didn’t accidentally setup certificate security, but found no such thing.
I suspect a firmware upgrade probably fixes that behaviour. If you want to accept both computer credentials and user credentials you'll need to name both "Domain Comptuers" and "Domain Users" in your policy.
By default, XP will re-authenticate with the user credential after the user logs-on (there is no way to do computer-only with XP, I believe).
Since I couldn't connect to my network wirelessly, I decided to connect to it by wire.
Then I just changed the settings of the router back to normal.
