gonna raise this thread from the dead and ask if you ever found out what the problem was with this? I have the exact same problems right now and im not getting anywhere fast
No I never did find out what the problem was, unfortunately. I had numerous engineer visits but the fault was intermittent which made it almost impossible to diagnose. All the times that engineers visited the line was working ok. Eventually the problem was resolved but I’m pretty sure it resolved of its own accord rather than anything the engineers did. The reason I say that is because the problem coincided with a period of hot weather and resolved when the weather cooled down. Also the problem would typically manifest at around 11am when the outside temperature would begin to heat up and the problem would often subside in the evening when the temperature was cooler.
And this summer during the long heatwave that we had the problem reoccurred, and it was even worse this time. In fact my connection was unstable for the duration of the heatwave and then after several weeks as the weather began to cool down the problem disappeared again. As such I’m convinced that whatever the problem is, it is heat related. The heatwave would have been the ideal opportunity to have the problem looked into again as it was on this occasion much more more persistent and less intermittent. But I just couldn’t be bothered with it anymore. I’ve had so many engineer visits it just became tiresome and I’m lucky enough to live in an area that now benefits from CityFibre/Vodafone fibre to the premises, so I’m going to switch to that when my BT contract expires.
