Mid December my BT VDSL2 connection suddenly started playing up. It had gradually dropped down over 2019 from training at about 65 Mbit/s to about 20 Mbit/s but it suddenly couldn't stay connected for more than a few minutes. BT said I had over 800 disconnects a day so they sent an OpenReach engineer.
The engineer measured the connection between the connection box on the front of the house and their cabinet and that was fine on a couple of metrics. He then replaced the master socket to the latest model (with built in filter) and the metre of cable between that new master socket and the connection box on the front of the house. He also reset the DSLAM and speeds went right up. We assumed it was now fixed and he left me with a 70 mbit/s connection that was stable for about 24 hours.
Within days the issue came back and OpenReach sent the same engineer to have another look. He measured no problems on the line but moved our connection to another port on a different board in the cabinet. This hasn't really helped all that much, the connection goes down every six hours or so.
I am starting to believe the problem might be with the Vigor 130. My cabinet seems to be a Huawei one and the connection "Fast" with G.INP support. The cabinet is perhaps 200 metres away, not that far. I am using the 1.8.4 BT firmware from February 2019 in 1483 Bridged IP LLC mode, VPI=0, VCI=38, Modulation=Multimode, MTU=1520. The 'alternative' firmware doesn't sync at all so that's no solution.
Is there anything I should change for the Vigor 130 to work better?
