I have noticed that even within a single day, the SNR can vary quite a lot. For example I could see a reading of 3.1/3.6 at one time of the day and then later see (as it is at the moment) 2.2/2.8. Would it be normal to see that sort of variation and what, if anything, should I read into it. Similarly, the maximum data speed shown in the Technical Log can vary throughout the day between 105Mbps and 110Mbps, although a month ago it was 134Mbps.
Does this mean anything to anybody as it is well past my expertise to interpret it?
Just normal fluctuations in your line and as long as your connection does not drop then there is no problem. It is not affecting your actual connection speed
Thank you for that. No, I haven't been getting disconnections since a firmware update to version v0.21.03.07094-BT on 14th October. Before then I was getting disconnections every couple of days.
As long as connection remains stable then I would not bother about the fluctuations
