Help me set-up my spiffy new, Black Friday impulse purchase: the Airport Express. I have a wireless network that is *not* an Apple Airport Base Station. Instead, I have a 2Wire whatnot that provides to network for my house. I want to add the Airport Express to my home network so that I can connect it (the AE) to my stereo and still be able to surf/chat/whatnot. The 2Wire is in the office; the AE is in the front room. They are approximately 50 feet apart from each other. The signal for the 2Wire is (as always) at full strength. The AE is blinking it's little amber light. I've never run either the AirPort Admin Utility nor the AirPort Setup Assistant. In the AirPort Admin Utility, when I click "other" and attempt to plug in my router (172.xx.xx.x) & password, I get an error message: An error occurred while reading the configuration. So, obviously I'm doing something wrong. Thoughts? Help? Thanks!
