I recently got TalkTalk fibre (76mb) and was on the "fast" channel type and my line rates were 79999/19999 with 4-5ms ping but now interleaving has been turned on and my line rates have gone down and ping has gone up to 16ms. I don't see why interleaving has been turned on as it was working flawlessly on the fast channel type
