We don't have fibre and cannot get it, at least for now. We do have RBI and that works fairly well at the moment, though we have had major speed issues in the past.  We still get constant speed variations, though, with the result that the adaptive streaming keeps going up and down, which can be pretty annoying. On some sites I can fix a lower resolution to reduce the data rate, others don't give me a choice. They seem to be programmed by monkeys who just blindly assume everyone has perfect streaming all the time.

So if we could get fibre, would this change? Some people complain about low fibre speeds, but my question is about consistency. High or low, do they remain the same all the time or is it like RBI, that constantly varies?
