Modem sync has always been about 8-10MBps, since our exchange went to ADSL2+ (and was the first one). Later yesterday afternoon or early evening suddenly it dropped to about 500k down and 650k up. Did a modem reboot, swapped modem with a known good one, swapped the power supply, unplugged the phone line and plugged it back in (to wipe contacts). All the stats appear the same as before, but I did copy it into the help request as my memory is not that good. House was new-built 2 1/2 years ago with new underground phone connection to the pole, then overhead line to the junction at the other side of the road, all looks okay. Suspect exchange port fault. Help would be greatly appreciated. I can see I have not received a reply to my home e-mail address, but I can't see line stats remotely so don't know if anything has been done yet.
