Comcast.
They got pretty fast speeds, my grandparents have them.
DO NOT GET AT&T. I have them right now, they are terrible in my area. they sent us a letter like 2 months ago saying "hey yo getting U-verse in yo area!", and a month after that, we called them and apparantly they decided to give high speed internet to four people a mile from my town instead of a town full of way more people.
theyre basically handicapped.
