So the Openreach broadband engineer called in on Weds, line checks were fine over the full spectrum in both directions. Possibly an issue with the modem so that has been swapped out.
Upon reconnection exactly the same speeds.. odd? No evidence of DLM sensing the interruptions.......
So, I thought time to try a little test to see if I could shake the connection up a little and ran rapid resets and disconnects for approx an hour. No change, an instant reconnect at the same speeds.....
OK, thought I, lets try disconnecting overnight, next day an immediate reconnect at the same speed......
Is it possible that DLM has been switched off on my connection and I am on a fixed line speed? (This would explain why the connection cannot retrain to a higher speed)
That's actually quite a clever test you did .... and as you rightly state, it's almost as if the line is void of any line management. The fast and furious disconnects you undertook should by all accounts have sent the connection into line flap mode, or at least heightened downstream margin ... yet nothing.
You're right to ask the question about whether there is an issue, especially how the line is configured on the msan.
I would write in again, as the notes will be on file, and ask the moderators to request a network config check of the connection with Btw. (almost augurs of line clamping on the msan) .... allbeit a strange situation. 😉
