[Internet] Signal Levels / Logs / Losing connection intermittently
I'm having a problem where my internet will drop for 20-30 seconds, multiple times per day... Doesn't seem to impact TV, so I don't think it's a physical plant problem.
Roger's tech doesn't see anything when they check it... Signal levels look good to me, as well, but I'm looking for a second opinion.
Also, there's a message that keeps repeating in the modem log :
"Received Response to Broadcast Maintenance Request, But no Un.."
but no idea if it actually means anything, or corrisponds to the issues I'm having.
As you can see below, it's the Cisco DPC3825, I'm on Extreme (I think?) - setup has been static (modem, router, wiring, etc) for probably 6 months, nothing's been changed or moved around or updated. Issue's new in the last 2 weeks or so.

Your downstream signals are great ... but the upstream is really strange in that it's SO low, right to the point that there could be problems there. With your downstream I'd expect to see about 40 dBmV on the upstream.
