Random drop outs SH3 any solution?

[peteraguy]

Our SuperHub 3, keeps dropping out with messages in the log similar to these. It seems to be when there is more traffic, and it resolves itself in a few minutes, but is far from ideal when we are working from home

If you post up your Hub stats over 3/4 posts someone should pop along and spot any issues with levels and errors etc

There are lots of upstream T3’s and high Pre & Post errors. These are accumulative since in the was last power cycled, so we cannot tell how recently they occurred. So, please power cycle your hub and post a new set of stats after a few hours. We can then see if this is the underlying problem.

I power cycled the modem at 23:00 30/06/21 (22:00 UTC log time) and now have new errors.

Power looks within spec. Signal to noise looks OK.

T3 timeouts do not!

Are there any outages in your area?

The most useful and up to date info comes from the 0800 561 0061 number. Try that to see if there are any faults that the web service hasn't picked up!
