Friend bought his first computer. What router does he need for AT&T DSL?

I would think that AT&T DSL would come with a wireless router. You might want to doublecheck.

Failing that, I'm partial to Buffalo brand.

Important: Change the default admin password on the router and the wireless password immediately after setting it up. Then write both passwords on a piece of tape attached to the router. This is for whichever router you wind up with.
