bonjour global name and time capsule

I have a Time capsule and want to set it serve Time machine and act as a bridge for my existing wireless Linksys router. When I set it to wireless off, in order to get the network tab to show, and set router mode to off(Bridge Mode), I get an error message from Airport Utility saying I have to have a Global Name for Bonjour. I have no idea what it is talking about.

I have wasted two weeks on this D&%$ Airport update and am ready to go buy a bridge and an external drive. Please help.
