I just installed my new Motorola 2210-02 U-verse modem, and it connects fine when plugged directly into my Mac. However, when I plug my Airport Extreme (through the WAN port) into the modem, using the yellow supplied cable, the Airport does not detect the internet signal. I've gone through the various threads, but all seem to apply to a different combined modem/router (RG). Is there something else I need to do to use the Airport as my wireless hub? I also received the Linksys E1000 with the modem, but haven't opened it, since I had the Airport set up with my previous ATT DSL modem, and it worked great (several Airport Express units throughout the house).
Ok. I persevered and fixed the problem on my own, but wanted to post for others. It turned out that by re-sertting my Aiport Extreme and creating a new wireless network using DHCP (instead of PPPoE, as I had with my older DSL modem), it worked.
