Your correct. What probably happened is that your router is setup to automatically retrieve an IP from your DSL modem since bellsouth modems also double as routers (Most ppl don't know this) But anyway, what you need to do is log into your router. Where it asks for connection type change it to Cable Modem, Then there is an option somewhere, should be to clone the mac address and you want to do this. After that the router should restart and everything work fine. If not call your router manufacturer for technical support. You don't have to pay the queer $5 for comcast extra connections.
