Bit of background to help establish the facts.
I've lived in this house for 2.5 years. After a few months of teething trouble my home set up was sorted. Main Sky Q box in the living room. BT WiFi with 3 x Whole Home discs.
Sky Q Mini box in the bedroom connected to qa non wifi TV.
All worked fine. Did what I needed.
Recently remodeled the main bedroom and purchases a 2020 Frame TV and added a 2nd Q Mini box.
Every time the Frame TV upstairs was on, the main Q (2tb 4k one) crashed/froze.
Started infrequently and ended up going within minutes of set up.
So as a (hopefully) temporary measure, I've put one of 3 Whole Home dics by the Frame TV (one connect) and wired it rather than wifi
This appears to have stopped the crashing.
Surely though this is a massive problem? How can a massive household brand like Samsung have a UK market TV with wifi that crashes the leading brand satellite box?
