Yeah definitely keeping the old phoneline, more than useful during a hurricane power outage. Are 2wire modems known for being low quality because after searching...i've seen alot of complaints on other forums/amazon about problems similar to what i'm having.
I've never used one as I tend to avoid modem/router combos. 2wire seems to have an agreement with AT&T users both Uverse and DSL.
I like to have my modem and router separate, so if one breaks, I just replace that one and I can choose a stable router. If you're open to this idea, then continue reading.

I know some AT&T users swear by their SpeedStream modems although you'll probably have to look on eBay for that. I think there are the 4100 and 5100 models.
If you're looking for a modem that you can buy new, Actiontec modems are on Amazon, and Verizon now uses this brand for both its fiber and DSL lines.
Avoid the Motorola 2210. Those things barely last an year as I went through two of them.
As for me, I use an old Westell 6100 modem that a tech handed to me in pity.
However, if you choose a different provider's modem, you may need to change the VPI/VCI values according to your region.

As for a router, the Netgear routers tend to be reliable out of the box with no Linux firmware mod needed.
If you intend to look for cheaper alternatives and put Linux firmware on them, the refurbished Linksys E1000 is not a bad start although I prefer the E2000 or E3000.

Question that popped in my head, what do you use for your current wireless settings? G or N?
