Uverse is pretty much just dsl2 or vdsl If your line can handle 25mb, you can get teh tv package which uses the 2wire RG, but for all intents and purposes, the internet side of things is just DSL.

U-verse is not a straight dsl router, it carrys the tv signal and the phone signal as well, there is no bridge mode, you cannot dumb modem it. The standard uverse at&t gateways are a one stop ...

If you are unable to connect to the internet via U-Verse and seeing the Gateway Authentication Failure error, then here's the fix!
