Hi Mickey, yes I'm with BT (home) and am having very similar issues to yourself apart from any error messages.
I had a lot of trouble with my connection last year though I've had *all* wiring/connections from my machine to the exchange, replaced and/or renewed in the last 3 months. Even including the cable from the green box on the adjacent street corner, up through our purpose-built ground floor storage, and into our third floor flat. New internal boxes, cabling, the whole kit, etc. And I do mean all- checked and rechecked by a senior BT engineer on a weekly basis for 3 weeks thereafter- having put a rocket up the xxxx of BT's CEO. Since which everything has run smoothly and without incident.

This is really starting to bake my noodle now.
