NOTICE: CM3000 cable modem v6.01.04 Firmware Released
Getting some reports that this version of FW is being seen on CM3000 series modems from CC/XF ISP. Not sure if other ISPs will be seeing this. Maybe at some point.
This seems to follow up on la...
Sometime around 11/18/2025 Cox Communications upgraded my CM3000 to the v6.01.04 firmware. It has been unusable ever since. When connected up to a router, the internet connection is never completed. I've tried both an MR80 mesh router and an older R7000P. Luckily, I still have my CM1200 modem, which works just fine with either router.
This CM3000 is still under warranty, since I purchased it in August of this year (2025). Netgear support seems to be giving me the runaround: having me reboot, reset, reset, etc. They've never admitted to an issue with this modem.
Any suggestions as to how I can better get their attention and resolve this?
Had the CM3000 been fully associated with the ISP and then after that after connecting a router to the CM3000 modem, power OFF The modem for 30 seconds then back ON, then give about 1 minute power ON the external wifi router?
