Moved from Newnet to Xilo/Uno broadband (partial LLU via TalkTalk's equipment). Could not be happier. Not the cheapest, but Customer Service TOP CLASS (and in this country!).
Newnet "had" been fine for the last couple of years, but when I was migrated onto ADSL2+ . BT's DLM kept messing me about and Newnet could not get it sorted. Got the distinct impression that they were not interested in private customers these days, more commercial orientated. Now on a fixed IP profile with Xilo and get great (for how far I am from the exchange) speeds, 11.5mbps. Never goes down and great ping as well. Would recommend them to anyone (as long as you are not looking for a "cheap" service, which they are not).
