I've got an Apple TV and Fire stick running on AT&T U-verse broadband ... 9 times out of 10 it runs like a sewing machine. Every once in a while during football season it'll act up a little with video quality that's not as good, etc. Sometimes restarting the app helps, sometimes it doesn't. When it gets that way it seems to have the same effect on Apple TV and Fire stick, to where I think it's on ESPN's end as opposed to AT&T's. FWIW, I live in Oxford and have U-verse ... used to live in Madison and had Comcast, and my gosh it amazes me how bad an experience I had for years with Comcast - it was a caricature of dealing with a cable company. Insanely bad customer service to where I prayed it kept working and my bill didn't do something wonky so I wouldn't have to deal with them. U-verse has been a breath of fresh air by comparison - good, reliable service that costs almost $100/month less than I used to pay Comcast.
