Ok. Now
this is ticking me off. Looks like I'm stuck with their crud.
According to someone on their board (who works for them):
You cannot purchase your own devices any longer on U-verse. All customers must now rent a gateway as of earlier this year.
A bit more that they said about it:
With dsl, you can use your own compatable modem.
U-verse is differant. Your connector (gateway, router, modem, whatever you call it) is proprietary. Each connetion uses individually assigned equipment, and will only work for that one service assigned to it.
You USED to be able to purchase your connection equipment from ATt, and it was yours. though you could only use it for the assined service connection.
As of February of this year, (folks who already own their equipment are grandfathered in) all new equipment, and this includes equipment used to replace old equipment, con only be rented, for 7 dollars a month.
While you can technically get used equipment from re-sell markets, they will not work, as they can only be assigned to one service, and att does not allow the use of equipment not provided by them on new service.
Yes, i am onother att customer, and only speak for myself, butr i've seen numerous posts to this effect, and its right. You can no longer buy your own equipment and use it on u=verse.
The router model I have, 3801, is unable to update to the newest version of IPv6 anyways. So it looks like this model is reaching/nearing the end of the road.
Joy. Found this... so I can have two routers? I only need one.
You can put any 3rd party router you want behind the RG on DMZ or IP Passthrough, depending on what RG you have.

Sounds like it's more of a hassle than it's worth. Given that the ATT one will just fail within a year or so anyways. That's why I wanted to replace it in the first place.
