The tv closest to my extender is a new Samsung tv, I can’t make it through a show or a sporting event without it buffering and going blurry multiple times. Tech service keeps giving me the run around, did plenty of resets and refreshes, the last tech “enabled 5g” and said I should be good to go and left so I’m done with them. Any ideas. It’s literally the closest thing to my extender which is supposedly online and working just fine.
