I had an issue with my line a few days back where it almost died through a very bad thunderstorm and my router re-synced at 400k, putting my BRAS profile to a lovely quarter meg, and my SNR target to 15db I reported this issue to BT and they seemed to fix it next day with no worries, my line seemed fine however my target SNR was still stupidly high and hence causing low sync rates. 2 days later (earlier today) i get a call directly from a BT engineer at my exchange asking me what he could do to help me as he'd been told i was still having issues. There and then on the phone he adjusted my SNR target, turned interleaving off, and did a load of line tests, while i sat back and used the SNR tweak on the belkin to between us achieve a sync of 3.8mbit @ 5SNR which looking at my line history should stay solid throughout the night touch wood. Not bad for a 6230M 60DB att. line! Great work bt Thought they deserve some praise after all the slating they get.
