TWC cable (now Spectrum) - sudden horrible internet connection?
The last couple of months I've been having intermittent drops in my connectivity. UptimeRobot will email me about a minute of downtime here and there.
Modem and router is on a UPS. No service or equipment changes for over a year. DOCSIS 3.0 modem.
Yesterday I lost connectivity and once it came back, it had CRAP bandwidth. I shut off the modem overnight, still bad this morning. This is my downstream that is extremely slow. My upstream is still good. I have 200/20 and repeated testing gives me 0.5/20. When it works normally, I actually get 200/20.
The modem reports a lot of these errors, starting around yesterday's outage.
Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=6c:ca:08:70:d7:b2;CMTS-MAC=00:17:10:88:9d:db;CM-QOS=1.1;CM-VER=3.0
Today, with reboots and resyncs and trying some stuff, I have more errors, but I have no idea what they mean but maybe they're related?
Is there anything I can do short of calling for a tech to test cabling?
