I never saw a reason to upgrade a modem/router because of age. Only because one needs a wireless one when the old one isn't. Or because the LAN requires an N router. But that's not age.
What's your reason?
Only AT&T can answer your question. Possibly they "hardcoded" your logon credentials into their modem, and aren't willing to provide them to you so you can do the right setup of your new modem. Then you have a nice new modem that can't connect to Internet.

I'm still using the 3 year old freebie DSL router/modem from AT&T with my 3 year old macbook. I want to upgrade. What should I get? Can I upgrade without having to do anything with AT&T? Any suggestions will be appreciated!
