I have tried everything, a new router, switch to a wired connection, everything. I called them and for some reason they think that it isn't their problem as the speeds are fine when I don't think they realise that not everything is about speeds. I can see that other people have also had high ping spikes, are there any fixes? BT could not seem to tell me why it's happening. (It's usually when I'm watching a stream or video, or when my family are watching netflix downstairs on the TV)
