Win7 64bit won't connect to internet when using wifi adapter in Bridged mode.

I'm having a problem with my new Windows 7 VM. This problem doens't show up in my existing Windows XP VM.

Info on the setup.

Host: OS X 10.6.4, Macbook Pro 15" (non unibody)
Parallels build: Build 6.0.11822

Guest: Windows 7 (Windows 6.1.7600)
Network setup: Bridged Ethernet (default adapter)

Symptom. When Parallels is using the Wifi adapter in bridged mode it cannot contact the DHCP server to get an IP address. However, when connected to the Wired ethernet adapter in bridged mode it can contact the DHCP server no problem.
