Thanks for all your help guys, well after a few more weeks, i managed to get BT to let me go and im switching to BE next week, so fingers crossed i wont have any problems.
BT had always been stable for me, but the adsl2 line was fluctuating too much, i was syncing at 13000 and getting download speeds of 5.3?!
i had to reboot the router to get 9.6mb back.
and my upload would go from 855 to 448 and back again with the upstream noise margin at 23!
the other thing is, BE are estimating my line at 8mb, even though i am getting more. im not too bothered about this, as i think i will stay on about the same, obviously hoping for more but not getting my hopes up.
my line attenuation is really bugging me though, i dont think it should be that high. theres not a lot i can do if its an old or poor quality line but does any one know who i can contact to get them to check it out? without any ridiculous fees. in terms of wiring in my flat, all sockets give me the same result, and there is no master or test socket behind any of them.
il let you know how BE is when im active.
