This modem work for me, I am using ATT over Sacramento, Ca. I read a lot of bad and a few good reviews about this modem. I was wondering the same thing... will it work? When I called ATT, they didn't even ask me what kind of modem I have. They gave me a link and I just simply went there and register my modem. My point is, ATT don't even need to know what modem I have at all..... By the way, I plugged my modem to the network card, not USB port. So I don't have to worry about the driver issue.
