Wider than normal Max < Bearer gap


[link to this post]
 
I've just discovered I had a 40-minute disconnection from 9:05-9:45am on 2 July, so checked my stats. That might have been the day I had a power cut but can't be sure. (Edit:- It's nothing to do with the power cut whatever day that was. I have a clock still wrong from that, showing 5:10 (12-hour clock) at midnight. So the power cut was at 7am).

I used to run Bald_Eagle's stats until the modem firmware was updated to "06", and haven't bothered with the unlocked upgrade. I never saw a night-time SNRM as low as in the stats below, nor a "Max" more than a few hundred above "Bearer". Most of the time it was of course the other way round anyway.

Not only that but my downstream sync is the anomalous figure. For a long time now the down up have been 58.7/14.6Mbps or thereabouts.

I will check again in the tomorrow to see what the stats are in the daytime, but thought that difference remarkable.

Drat them tongue ! It looks like my modem was updated at about 5:30am today. I'm now on "08" software and can't do the comparison I wanted to do.

Due to the SNR no doubt.
