DOCSIS 3.1 Channel Maximum Speed
Sorry if similar questions have been answered elsewhere. I have checked here, and many outside sources but the answer is unclear. I am hoping someone on this forum might know. I have a CM1000v2 modem...

I presume channels vs QAM is in the formula. No idea though. For most ISPs, they use 32 channels for 1Gb speeds or higher. I guess some ISP are trying to squeeze more thru less channels?
What Brand and model modem do you have?
Post a screen capture of the Cable Connections status page.

Well your power is ok, but you have way too many correct and un-correctables being listed. Those should all be zero's.
Something you need to have the ISP review.
Also check cable lines, connections and fittings. Ensure coax jacks are screwed in well and tight. Center copper wire is good.
