I have a new ATT DSL modem set up at my daughter's house. It's a simple Motorola DSL modem that is not wireless. Today I attempted to connect an Airport Express to it. Didn't exactly work out. I had no problem getting the internet to it and keep the light green. But the problem is, even though I believe I tried about every way possible to set it up right, I kept getting the following error, AFTER the Airport Utility told me Congratulations that it was set up correctly: "192.168.1.64 in use by 00:1f:06:e:6a, DHCP Server 192.168.1.254" I tried this on a MacBook pro and a Macbook with the same result. I also tried a PC and it connected once, yet never connected after that. So, there is some sort of conflict and I'm not savvy enough to figure it out. BTW, the ATT service is the $19.99 basic service, nothing special. I really don't want to go into the modem and mess with the settings; what's the trick to get the Express configured right? And, I did bridge mode, regular mode, and everything else I can think of. ATT did not provide me with IP addresses I should know about. I'd like to get this working, but I guess if not, I can replace my cable modem with the ATT Wireless Gateway and have it all in one package, but that's not a versatile as having the Express. Thanks! P.S. I saw this problem elsewhere on the net with no real resolution.
