Thank you for the reply Starman, yes the engineers that came out performed the test and they said it was perfectly fine, the problem started off intermittently but now it's become a daily occurrence, just very confusing, BT said there are no faults showing up on the line on their end, thr only thing i can think of that is causing the issue is if my smart hub 2 is faulty.
Looking at the logs you posted I can see one drop in internet connection so is the problem more the drops in your wireless connection to devices rather than drops in internet. does hub light stay blue
With the number of drops in connection you experience if it is hub then I am surprised that your down noise margin is 3.6db whereas I would expect the DLM to have taken action by now and noise margin to be 6db+
No, the hub goes to purple then flashes orange until goes back to blue when connection starts again.
A >3db SNR on the downstream would likely indicate that G.INT was enabled by DLM on the line in the past.
What kind of line stats are available on the SH2? Any ES SES values available to endusers?
