Oh, I should've mentioned about ATT, their 2Wire Modem kind of sucks depending on what you are doing. When I lived alone, when I had Xbox + PC + Wireless Laptop, it was usually fine.
When I got a roommate and had 2 computers and an xbox constantly connected, it kind of sucked. I would assume that it will work fine for you, and I'm sorry I didn't mention it sooner. But, other than that you should be good to go. <3<3<3
