Ideally you should have zero PostRS errors on the circuit.  These are packets that have to be re-transmitted as they cannot be corrected, unlike PreRS errors. So, there is an issue on the circuit, possibly noise ingress.  Also you have 18 T3 timeouts, which IMHO should be lower. 

Post the network log as well for completeness and comment, and setup a BQM to monitor the state of the circuit  www.thinkbroadband.com/ping

When done, post a link to the shared live graph.  It may show more information.

All you can do is make sure the connections are "finger" tight from the Hub to the outside omnibox on the wall.

Otherwise, wait here a day or two for a VM Mod to pick this up and discuss.

        Since my most recent modem reboot, the error rate has lowered still getting pre RS errors but nothing post RS, The DOCSIS 3.1 uncorrectable errors is still climbing though up to 24k now.
