My 6 year old DSL modem is apparently dying. Turning the power on and off to the modem immediately brings it back for a while, but it is unreliable. I added on a router for a workstation and a hardwired network printing and an access point for wireless, but I would like to replace all of these pieces with a single unit. Requirements are compatibility with AT&T DSL, a hardwired network printer and workstation, and N and G wireless. Anyone have suggestions? Thanks.
