Hi,
I'm having issues where my broadband will slow down suddenly. Not sure what is at the root of the problem. My monitor is below., along with downstream and upstream.

@TeamFergus I have moved your post from the Tivo board to the broadband speed board as it is not a Tivo issue.
The hub stats posted so far mostly look OK, although the 16QAM on the upstream and the large number of T3 timeouts is unusual. Some packet loss on the BQM but it doesn't seem consistent throughout the day. If you could also post the network log from the hub that might shed some light on the issue.
When was the hub last restarted?

I don’t see anything untoward in the log.
If you can’t remember when it was last restarted, then it might have been some time ago and the upstream timeouts may be historical. Worth restarting the hub and seeing if that makes a difference. If not post the updated hub stats a few hours after the restart.
