The SURFboard is not on the list in the link you gave me. I found the specs for the SBG6580 at Motorola
http://www.motorola.com/Video-Solutions ... ys/SBG6580and in the specs it say-
Extensible networking, allowing customer to network up to 253 desktop computers, laptops and other Ethernet or wireless devices to create a full Class C network
but in reading the specs I don't know enough about networking to be able to tell if it can be used as a modem and a router at the same time. I'm posting the specs in hopes someone will be able to tell me if what I want to do is possible.
The SBG6580 is the ideal competitive solution for the high-end residential user, the small home office owner and medium to large businesses.
