I'm getting a more solid line of dropped packets showing than usual.
For a long time now - probably since last March - we've seem small blips of dropped packets between perhaps 4-4.30pm and 10/11pm, and it hadn't really caused any problems, but three nights ago, I noticed it suddenly became far more pronounced, and so far has been at roughly the same times.
I searched and thought about it for a long time when it began in a small way last spring, and seeing we had no problems, nothing in use in the house at those particular times, or new electrical items, I did wonder about a new family that moved in opposite.
Seeing these heavier strings of packet loss are at the same times, it must be the same source wherever that is.
As far as I know, we've had no major work happening close by - Virgin installed fibre along our street, but it never seemed to affect our router performance. I did see one house opposite being connected to the Virgin service in the past week, but that's a different cabinet anyway.
I'm now noticing some slow movement with the internet at those times.
