looking at the btspeedtester your profile is correct for your speed and the throughput/download at 1988 seems ok for a weekend with others using the net.
have you had a reset in last 24hrs which corrected your profile?
what about btspeedtester so you can compare with previous figures?
This is uncanny, I live in Maidenhead (same code 01628) and have had exactly the same problems as dav reports. My connection has been great since I signed up; however in the last few days it has fallen away for no reason. Your stats are almost exactly the same as mine as well. Maybe the Maidenhead area is experiencing some problems with their servers? I wonder if they are aware of this?
your speed is slightly lower than before but profile still the same. your throughput/download is really low compared to last time. did you contact the mods? http://bt.custhelp.com/app/contact_email/c/4951
can you post new stats and also btspeedtester results to see if any difference
