Update ... The single thread episode was short lived. That said, my connection went mental just after midnight. Disconnections every minute or two and speed flapping up and down like a see saw. My thought then, was to revert to the BT approved Zyxel AAISP supplied and configured router, despite how bad it was initially, especially as I may have a so called SFI turn up - A couple of re-syscs on from that, my available speed jumped up 13Mbps to near 66Mbps - about 2Mbps short of the 68Mbps I had initially last time I had FTTC. Also, wonder of wonders, it has stayed stable overnight. Obviously some auto adjustments overnight and wonder if G.INP has been applied, though my minimum latency is about the same. Either way - Fingers crossed and leaving hardware well alone for a while.
This apparent DLM brainstorm has been the problem all along with BTW services. To my mind, if DLM decides because of errors, noise ot whatever to slow things, surely it should keep things at that new speed for a while - Not keep flapping up and down every minute or two by many Mbps. To my mind, it's a cab/exchange equipment problem. A view that was shared by Pulse8 when with them. But suggesting changing a line card or whatever at the exchange sends OR engineers ballistic. Apparently it needs special dispensation from somewhere deep within the bowels of Openreach. Anyway - image of after midnight adjustments. The fact that the far higher speed is holding, suggests to me no serious noise on my line.
