Hi,
Over the past few weeks I've noticed that the noise margin temporarily rises between 1 and 2dB.
This takes my max speed from about 76 to 80mbps.
The time period can be between 10 mins and an hour, so it appears that a 'noisy thing' is going quite for a while.
Any ideas on how to track this one down?

Can you look at the individual bands in more detail? If you can get some idea of the frequency bands affected you might be able to use a radio receiver.
Does it occur at the same time of day or within certain time slots? Try keeping a log.

Maybe the noise margin temporarily rising is someone nearby switching off their VDSL2 modem for a little while, temporarily reducing the crosstalk.

That thought crossed my mind, but it's a whole dB, so I'd have thought they'd need to have badly balanced line for that much cross-talk, so I'd consider that after checking other factors, and see if there is any pattern. I do note that the "off" time is nearly an hour - the suggested time for turning off a Fibre modem to hopefully avoid DLM issues when a resync is wanted - could be coincidence!

Thanks all,
I'll keep an eye on it and recod as much as I can.
It might take a considerable time to gather sufficient data to even attempt of get a conclusion.
