CM1000 Rock Solid at 500MBps until I upgraded Cox to 1000GBps
I've used this modem for many years at speeds between 200-750MBps without issue. At my current location I've been using it at 500MBps without issue for 7 months. Then yesterday I upgraded to 1000MBps...
Find you a -6db coax line attenuator to put in line between the modem and ISP coax line.
FYI, the modem doesn't output any power, only recieves what the ISP is putting over the coax line.

Tech just left. He said there was very low signal loss (around -47dbm) up to the modem and that Cox has no ability to change the power output of the modem. They reprovisioned the modem, but it still has high power levels of 8.5-11dBmV. The tech doesn't know what else to do except get a different modem. I don't really want to do that, so I'll let it ride and if it drops out any more I'm going to go back to 500MBps where it had been rock solid for 7 months.
The LAN cable between the eero and the modem is a Cat 8, and it's the same as it has been for months, so I don't think that's it, either.

Thank you, Furry! I can't believe I didn't think of that. Much appreciated!
Also be sure to speed test with a wired PC connected directly to the back of the modem as well. Help rule out any performance issues with the external wifi router.
