Can I replace the AT&T-supplied NVG 599 modem router with my own?
I have AT&T DSL internet with an Arris AT&T Uverse Gateway Modem Router NVG599 that I must rent from AT&T. I found the same modem/router on the internet for a reasonable price including power cord. Can I just replace the modem and contact AT&T or is their more to it. AT&T says you must use their modem/router. Is that true?
