Have seen my sync rate reduce by 0.5 mbit/s increments from full 8.2 to 7.2 - lose 0.5 mbits/s every few days. Connection rate normally stable for 3 days then at next connection it reduces by 0.5 mbits/s
I use an adsl modem and do not have the machine on more than once or twice a day for 20/30 mins at a time.
At weekends I would be on several times for 10-15 mins-60 mins at a time.
Is the equipment at BT mistaking my startup/shutdowns as problems with the line and reducing my sync rate?
