Hello,
Similar to an issue I was having about a year ago that turned out to be a network issue and was resolved at the time, I'm again getting connection interruptions, packet loss etc correlated with signal issues in the modem stats. Around the time it happens, I generally see upstream power levels climbing, T3 timeouts reported, partial service warnings, and occasionally lost upstream channels.
This being an upstream issue also seems to agree with observed behaviour e.g. in voice calls - I can generally still hear other people clearly but they report my voice cutting out. I set up a BQM and see red packet loss spikes nearly every day now. I've left it for a couple of weeks to see if it gets resolved but the problem remains.
I've checked all connections are tight, rebooted modem (several times), checked for problems with the automated checkers, etc. I wonder if a mod could look into this for me?
Thank you!

Technician visited this morning, replaced hub and took some steps to improve RF levels, also raised a ticket with networks in case intermittent interference is to blame.
He said to monitor it over the next week or so and see what happens.
