Any suggestions would be greatly appreciated. So I'm honestly not sure now if everything is happily connected, and DHCP requests are failing to be passed, or if it really isn't a functional connection. However, Nothing on the other side of the WCG-GN can get an IP address automatically anymore. More specifically, looking at the WDS screen on the WCG-GN, the Connection Status is '-' which it says indicates that there is nothing wrong. I have hard reset the WCG-GN, tried connecting through AOSS and through the manual instruction found here. Diagnostic on WCG-GN said that the bridge wasn't connecting, and nothing on the other end of the bridge could connect anymore.

So these actually were set up and working for a while, and then last week, the connection stopped functioning. Crossposting this from the Buffalo forums.
