Windows 7 - Windows 7 kills internet connection for entire network on Westell Router

My home network loses internet connection when Windows 7 is active.

I have three machines with XP, one Apple and my current laptop with Windows 7 all connecting to the internet through the same router. After about 5 to 10 minutes of Windows 7 running I lose internet for the entire network. I have been able to replicate this problem six times consecutively. The router will indicate that the internet connection is active, but it is not. If I reboot my laptop to XP I must also restart the router to regain the internet connection to the entire network. Also, all computers see the network as active and running properly even when there is no internet.

Windows 7 machine is a Dell Precision M6300 fully updated with necessary updates and drivers from windows update.

Router is a Westell VesaLink Model: 327W this a standard issue wireless router from Verizon DSL

Many thanks in advance,

I updated the Firmware in the router. Seems to have fixed the networking/internet disconnect issue.
