Its their service, the longer you download the more they throttle it back. They give you fast speeds at first but then nail you a lil later. I quit their service it got so bad, I was with Cox for 4 years before that and it was great, suddenlink took over and it went instantly to shitsville, population me. Not much you are gonna be able to do but bend over and take it till you can switch. Try calling them daily and complaining, they may cut you off then and you would be screwed.
