I have cox cable internet here, and they will not support Linux, but it worked great from the get go, and i have never had an issue. The internet service does not know it is linux, it just sees a port. The question is does your linux see that port. That question is answered in a second when you plug in the cable from the modem. My guess is yes. I believe you have Ubuntu, if so when i tried that one it saw my modem with no setup
