Not too bad:

The spikes which caused your loss of sync were pretty dramatic. You have a bit of a waiting game I'm afraid. If you are lucky it is something inside your house. If outside you may never pinpoint the problem (and even if you do there may be nothing you can do about it).

It has been fine all day:

Hopefully this is a good sign!

Touch wood. You can see a slight downward drift as you would expect as day turns to night and radio intererference increases.

As expected, the SNR is dropping, but there haven't been any large blips (yet):

Dropped to 5dB where it was previously at 6dB about 10 minutes ago:

Noise Margin: 5.3 dB
Connection Rate: 6304 Kbps
Line Attenuation: 41.0 dB
Power: 19.6 dBm
Max Rate: 6848 Kbps

I assume the sudden drops are quite recent. Any changes you can think of around the time they started?

Happened twice today:
