I mean it's not a reliable technology compared to 40-year-old cable or 15-year-old digital air tv.
Youtube streaming is relatively ok but not 99% reliable. Digital air TV is 99% to 100% reliable. I wish my streams were just as reliable as the older cable or DT by air, but it is not the case.
So we have much better quality signals than, say, 15 years ago but streams other than Youtube may buffer now and then or freeze or stop and require reload. This stopping actually occurs even in Youtube. Until buffering is solved streaming won't live up to the HD quality of the signal.
I am talking from my experience with my 100 Mb connection. What's yours?
I guess the most immediate solution is in 5G.
Sounds like you need a new provider
