Setting up Buffalo’s WZR-HP-G300NH for ATT DSL

Welcome back, everyone out there on the Internets. Today I noticed something rather striking.

When I was looking for setup instructions to get my newly acquired DD-WRT based Buffalo router back on ATT’s DSL network I found a marked lack of decent information.

There were plenty of people complaining about how they couldn’t get it working, but not a single one stating, “here’s the fields you need to fill in”.

Now, there might be some of that on the actual DD-WRT forums. But that’s not what was coming up in Google on the searches. Which is what led to quite a bit of frustration on my part, as I like to have a bit of guidance in advance of actual setup to make everything go smoother.

So! What does it take to get ATT service running over a directly connected DSL router, where you’re ignoring the DSL-Modem bridging device from ATT and directly servicing the line with the new DD-WRT router? Not much. Just put in the user name (generally user@someurl .com) and your password and you should be all set. I’ll check and see what the other settings do (if the compression works or just breaks the line entirely) as I get time.
