You do not need the exact same router, just get one that handles the speeds BTL offer. They use that Cisco router because they get a deal for bulk purchase. This is a good model. DSL-2640B ADSL2/2+ Modem with Wireless Router
you are 100% sure of this? as in you've done it or knows someone who has. Im not saying its not possible technically spealking; I know it is. I just want to make sure they allow it.
i figured they might say "we dont know how to confirgure this model sorry" ya know?
