New CM1200 modem download speed capped at 100Mpbs
Last Sunday (10/17/21) I replaced my Surfboard SB8200 modem with a Netgear CM1200. I had been using the SB8200 since early 2017 when I upgraded my Cox Internet service to 500Mpbs download. The reason...
The best option was to use the Arris SB8200 and it works flawlessly. The CM1200 was actually cheaper since I am retired from the military and use the military exchange (retail sales without sales tax) aboard the military base. So the CM1200 was returned and I am using a new SB8200 and download speeds are a consitent 570Mpbs and the light on the front of the SB8200 remains a constant blue color instead of green. I really wanted the CM1200 to work out.
Do you have a screen snip of the cable connections page and the event logs?
I've seen ISP's assign different frequencies at times which is why sometimes a reset/reboot/ISP reboot can fix issues for a bit. And then later it goes back to the frequency that is having issues.

Next time, would have been good to see a screen capture of the Connections status page and Event logs to help better determine what may have been happening. Glad you found something else.
Enjoy.
