CM1200 useless on Charter/Spectrum after they enabled OFDMA on upstream channels
Purchased a CM1200 modem a few months back to use with my spectrum service. Has been working fine for the last 3 months with OFDM on the downstream channels and regular upstream bonded channels. Ab...
I was able to get two contacts at netgear who coordinated with spectrum and pushed the newer firmware out to my modem and exempted it from being downgraded. I will PM you their email addresses. They are well aware of the issue and pushing to get the firmware approved for system wide deployment to all users running the CM1200
Received confirmation from Charter that the new firmware has been approved and was handed off to APODID – Device Operations on 6/10/21.
They have started pushing to owners of the CM1200 and plan to be finished rolling out to all by 7/9/21. Please advise if you receive the update. Version should be 3.02.01.
