Here is my setup. I have a Macbook, Thunderbolt display and an Ethernet connection plugged into the Thunderbolt display.
During the day, most of my network use can (and should) operate across the ethernet associated with my display. However, I also need to be able to connect up to a wireless router. This hasn't been a problem on the Mac OS X side, but the program that I need to run on the router has to obtain an IP address from the wireless access point.
Considering my current setup, how can I leave it so that I can access the internet in OS X, yet have my Window 7 instance running in Parallels, get it's assigned IP address from a wireless router that my Mac is also connected to?
I've fiddled around with the Parallel's network settings for an hour, and I can't get Parallel's to see the router, even though my Mac is certainly connected to it.
Thanks to Emgee for providing the correct answer, however, there was something else going on that I was able to fix via trial-and-error.
After setting and resetting the various network options I was able to get my guest OS to obtain an IP address from the WiFi router. I'm not sure what step I executed fixed Parallels, but I tried to following steps and, eventually, Windows 7 "magically" started talking across the network.
First, I shutdown Windows 7 and went into the hardware configuration of Parallels where I deleted ALL of my network adapters (I had two, because I tried to create a second one, specific to the WiFi connection.) After deleting all of them, I created a new one and specified it as a bridged, WiFi connection. I also, hit the
Generate MAC Address button a few times, just in case Parallels was cacheing addresses.
After reseting my network connection, I restarted Windows and I was able to obtain an IP on my WiFi subnet. Sending pings in both directions verified that I was able to send and receive data both ways.
