Frequent Downstream Errors & Very High Uncorrectable Codewords
My service has been fluctuating between excellent and awful lately. I have the Netgear CM1000v2 modem with DOCSIS 3.1 and I'm on the 600 Mbps plan.
The downstream OFDM channel seems to have power levels that go up and down significantly. The Uncorrectable Codewords are very high at times when I notice a problem, and low when things are fine. Logs show many instances of CM-Status code 1, 4, 5 - along with 21 and 23. It's very obvious when errors are happening because the mouse pointer on my remote work session skips around and is sluggish (VMware horizon). Also, I get a lot of buffering and disconnects when streaming video.

Hi @OFrabjousDay!
Sorry to hear about the lagginess you're seeing! You sound like you're pretty comfortable with tech, but just to cover all the bases, is the coaxial cable unkinked and unbent? Are the connections at either end snug, but not super tight? Is there a splitter on the line inside? Do you see any damage, fraying or corrosion on connections?
