Dead times on phone; tv freeze - DirecTV

When talking on our land line, we have spots where the person on the other line is suddenly cut off for a second or two and we miss the meaning of the sentence spoken. Our tv has freezes periodically where it just stops and suddenly jumps back to the program. I connect the two with our recent bundling to att uverse. Very disturbing. I recently jacked up the speed starting November 1. Could this have anything to do with it?
