I have a problem: I can no longer access the internet via my Airport wifi simultaneously on both OSX and the Vista virtual machine. Problems all started when I loaded OpenDNS as a means of trying to eliminate the annoying "resolving host" problem in Google Chrome browser. I've since deleted OpenDNS, but I can no longer get bridged networking to work. Any help?
Try running the Parallels installer from the .dmg? In the "Network Adapter Settings" page in the Parallels Desktop help, there's a section about "WiFi Bridging Support".
