As mentioned previously, on the odd occasion routerstats can show an unexplained dip of SNRM down to zero. This is usually if say the router is busy doing something else, or if routerstats just cant access the figures from your router for some reason or other at that moment in time.
The 14:59 looks like an unable to access as the SNRM both sides is pretty even. I wouldnt worry about those ones.
However at 20:38 ish that looks like you perhaps have had a noise spike which has caused the router to loose sync. SNR started a slow decline at about 20:20, then a tad later it dropped so much that the noise drowned out the signal and you had to do a full resync at a lower speed.
Did you put the kettle on?
In fact looking at the 2 graphs it looks like sometime between 15:40 and 19:40, there must also have been a decline in SNR (graph not shown), but sometime between those 2 times there has obviously been a decline in your SNRM. It would be interesting to know if that was a slow decline, or a more sudden drop of around 3dB all at once.

So my translation wasnt necessary then?
