New vista computer shuts internet down

[vanscars]

HI, I have read through tons of posts but cannot seem to find my problem any where. I recently bought a new vista desktop and connected it to my dsl wireless router (westall versalink 327w) with the most current firmware installed. One of the existing computers is running XP and wired to the router. The other is a laptop running vista and connected wirelessly. After connecting the new vista desktop I lose internet connection on all computers after 30 minutes or so. The only way to get internet back is reboot the dsl modem. I have contacted ATT and they ran line tests and all is good. Computer came with norton internet security and i have tried to disable it as much as possible with no luck. If anyone can help I would greatly appreciate it. If I need to post more info let me know. Almost forgot, If I reboot modem and disconnect newest vista computer I have no problems.

Thanks

Posting the result of ipconfig /all may help.
