Wireless Networking Doesn't Work

Hi DaneM,
basically, in Shared Networking Parallels Desktop virtual machine uses internet connection that is currently on top of networks on Mac side: System Preferences > Network (you can drag wireless connection to top). Windows virtual machine does not connect to internet directlly. As first troubleshooting steps, please try the following:
1. Reinstall Parallels Tools by removeing Parallels Tool entry from Add/Remove Programs list, restarting VM and installing Parallels Tools from Virtual Machine menu.
2. Try to switch between Shared Networking and Bridged with Default Adapter or vice versa
3. Please check this Knowledgebase article: http://kb.parallels.com/en/5664 , it is applicable for PD 5 too.
