The previous post is not for a manual.
It turns out that AT&T does NOT allow Netgear to publish a manual, so you are dependent on AT&T phone support for any technical problems you might encounter. So if you ever change suppliers, you will have a hard time using a 7550 modem/router in your new application.
So if your somewhat technically savy, I'd recommend that you buy a generic modem router, making sure of course that it comes with a manual. And their technical support will probably already knows how to deal with AT&T anyway. (You can ask about that prior to purchasing the device.)
As a last note (I haven't done the research), Netgear probably has a manual for something like the 7550 that you might search out.
