We have had a 32” Samsung smart tv for over 6 months now without a problem. The tv is hard wired to the BT infinity hub. A few days ago I started having BT sport. I (try) to watch it through the BT SPORT APP on the smart view menu on the tv. Since then I haven’t been able to watch a live football match on it. The match is on for 16 seconds the off buffering for 7 seconds, making it impossible to watch. On the NON smart tv in the bedroom (much further away from router) I can watch BT SPORT without a problem via an Amazon Firestick. I’ve tried various things to get it to work on the smart tv without it working. I’m not an internet techie and don’t understand most of the jargon. I just want to watch BT SPORT through the smart tv.
