I have Windows Vista Home Basic on a Dell laptop that I am trying to connect wireless to my Linksys router. For some reason when I try to connect wirelessly to my router with this Vista laptop I am getting the message "Windows Has Detected An Ip Address Conflict"

I tried my XP Pro laptop and it connects with no problem to the Linksys router. The Vista machine is actually showing connected but no webpages will display and the IP address conflict message keeps popping up.
