I am using this with a separate (external) cable modem on Comcast/Xfinity in a family member's apartment. I am not familiar with AT&T, but given that this is only a WiFi+Router (does not have a built-in cable modem) I would be surprised if it didn't work (assuming you have a working cable modem). It can be configured for dedicated/assigned IP or DHCP (I'm using DHCP with Comcast/Xfinity). So far, it seems like a good WiFi router for the price. It is being used in a fairly small (5 room) apartment, but the signal seems to be good throughout.
