General Mac hardware discussions forum: new modem airport

I'd have to know a wee bit more. Such as the model/make of the Comcast MTA (or modem as you may call this black box.)

Arris model tm402p/110

was not dsl i was using a motorola box before now this new one both cable modem. tried a hard reset still connects to network, isp, but fails at internet and server

and I'm sure you have tried this.

Power down everything. Modem, airport, computers.

Bring them back up again one at a time. Modem, airport, computer.

Take a look at the Airport Utility and see what IP address it has. It "shoud" have a Comcast IP address.
169.x.x.x does not cut it

the great thing about apple is it works. I don't know what the problem is and have spent alot of time on it what if I would get say a cheap netgear wireless router and hook it up, it should automatically pick up the settings right? It was to be something I am not seeing in the airport settings because the imac hooked up to the cable modem via ethernet cable works. Thanks for the help!

Hello was this resolved, if so how? I just ran into this same exact problem.
I went to a friends house to setup up his wireless airport extreme (white, 1 phone modem, 2 ethernet WAN/LAN ports) to his recently installed Arris cable modem. When I arrived the cable modem was plugged into his MacBooks ethernet port and working perfectly. I unplugged it from the MacBook and plugged it into the APEx WAN port. I used AP Utility to set it up using DHCP with cable and dsl modem. Nothing worked. The MacBook sees the airport and hooks to the wireless network I created but no internet or mail capabilities. This stumped me, I've set up a number of airports using the DHCP setting and they just worked.
