    I installed the new Comcast cable modem two days ago. The outputs include a single USB port , 4 network ports, and 2 phone lines.

    Will any Apple device (Airport Extreme/Airport Express) work seeing as there isn't a WAN port to connect to?

    Are there any other possibilities?

    My iPhone and iPad won't connect to the new modem; my Mac Mini works fine, however.

    It will work if you select "Router Mode: Off" in the Network page of AirPort Utility. You'll let your modem do all the routing functions & use the AirPort only as a wireless access point & Ethernet switch.

    There's likely also a way to turn off the routing functions inside the cable modem, which is what i'd rather do.

    As already stated and to help clarify. Your Comcast is a modem and router. You can't have 2 routers assigning IP addresses. This is a conflict. If you want to use an Extreme as the router then you will need to put the Comcast in "bridged" mode if it allows.

    Also you probobly pay a monthly rental fee ($5-$10) and would be better off in the long run buying your own cable modem (example).

    I was in the same boat, but got some help on twitter by messaging this guy @comcastwill. He turned off the router but let the modem work fine and now I have my airport extreme working great
