Buffering and poor picture quality on Hi-Def Uverse Tv
My TV has been buffering the picture and generating grainy definition recently. It is wirelessly connected to the ethernet box. An ATT technician said I needed to upgrade to fiber optic so the TV would be better at Hi-Def but the ATT telephone support said that fiber optic would impact the Internet speeds more than the TV and the TV could be improved simply by hardwiring the ethernet box to the TV modem. Which is correct?
