Hi.
I will try to summarize this as much as possible.
Just moved to a new apartment. Got AT&T Uverse, internet service only.
Since I frequently use the music streaming on my airport express, I really wanted to stick with that setup. AT&T sent me a Motorola modem and separate Cisco/Linksys wireless router. So, obviously, I plugged in the modem to the airport and put the Cisco router in storage.
Initially, everything seemed to be working. But the airport was giving the constantly flashing amber light, and after only a day of use, I had to restart the devices a couple of times.
So, I go into Airport Utility, and though I can't remember exactly what it said (and may get the terms wrong), I think it basically boiled down to "hey, both me and the modem are trying to hand out ip addresses, so put me in bridge mode." I thought that was odd, because since when does a modem hand out ip addresses? But I put it in bridge mode anyway (it was originally in "distribute a range of ip addresses). Then, nothing worked. Not even when I reset both devices back to factory settings. Some folks online seemed to suggest that I should put the modem in bridge mode, but that didn't appear to be an option with this model.
Anyway, what I did that eventually worked was this:
-change the only setting that I could on the modem from "something private ip address" to "provide public ip address"
-changed the airport settings to "share a public ip address"
-that still didn't work until I manually changed, in airport utility, the DHCP beginning address to one higher than that of the modem (the modem was xxx.xxx.7.xxx, so I put xxx.xxx.8.xxx in the airport settings).
Everything seems to be working fine. But, what the hell is going on?
Sorry, I'm the kind of guy that isn't just happy when something works, but rather wants to understand WHY it worked.
