I have GoldenWest as my ISP in South Dakota. Currently, my connection is bridged from a d-link router required by my ISP to an Airport Extreme and is connected by an ethernet cord. I recently inherited another Airport Extreme and want to extend my newer Airport Extreme to this one. However, every time I change my Airport to "extend a wireless network" and update the Airport, it screws up and is unrecognized. So is it impossible to extend this wireless network while it's in bridge mode? I'm running Lion, but I tested it on Snow Leopard on another Mac, and it does the same thing. Any ideas? I wish I could just plug in my wall connection straight into my Airport Extreme, but I don't think ISPs, in general, will let you do that. I have had to login to their d-link support page before by typing my router number into a browser, so I'm not sure if maybe I have to do something within there as well.
