Following a long spell of stable connection at 5120kbps giving profile of 4500kbps and a consequential download speed of approx. 4250kbps, overnight I find I have auto resynced several times with an increase in sync but with a read download speed of only 1900kbps. Furthermore the BT speedtester will no longer allow me to carry out the enhanced diagnostics. A call to support reveals a correct 4.5 profile and shows up no line faults nor reason for this situation. Support say they have raised a fault for me but no news yet. The only change I can see is that I am now connected through pci-ago1 rather than ag03 as was the case before the resyncs.
Can anyone suggest a cause and/or a solution please?
Perhaps a Plusnet rep on this forum can look into current progress.
