I have a three hub router in North Bristol and I'm also having constant trouble. Was okay about post 3 months ago. I've been in touch with customer support and they tell me different things, first that there's high usage in area, also that there is maintenance going on at local mast until 30th June. This was obviously crap as no improvement to this day. All I'd recommend is get out as soon as you can. Customer service is terrible, the most they can offer you is £20 credit for the month of practically useless internet.
