I have a wireless network with 5 access points. The router is a WRT54GS and the access points are WUSB54GP. All the machines are on WIN XP Professional except one which is WIN XP Media Center. All have SP 2 install. All connect fine except the WIN XP MC machine. That one associates ok with good signal but it will not connect to the internet. I am wondering if the fact that it is using WIN XP MC as an OS is causing the problem.
