Hi all, I have 3 now tv boxes- up until 2/3 days ago all were working fine. we always have 2 on, and 1 switched off and rotate depending where we are watching tv. The picture quality is so bad on all of them you can barely make out characters on the tv anymore. I have read through the forum on other people's answers and my wifi is fine etc etc- any other suggestions on what to do before I cancel and find another TV provider? Thanks!
