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 have two contacts at netgear who worked on my behalf to get my own modem upgraded to firmware version 3.02.01. Charter should be making 3.02.01 the new default version for anyone using a CM1200. They are dragging their feet and not responding to my repeated emails. It is very frustrating. I have threatened another FCC/BBB complaint as others are now reaching out as they enable OFDMA in more markets across the country.
Interesting. Well here's hoping I can eventually get that done. This a user-initiated thing or something done on Spectrum's end?
| Hardware Version | 1.01 |

Well after A LOT of reading on this same issue with threads even you replied to, I feel bad even bumping this thread to the top!
Shame on Spectrum for holding out this long. I wish I knew when they did this "upgrade" and it sounds like I need to dig down deep to get it fixed. Sad.

Guess that FCC/BBB report is in order.
Ya, It's up to ISPs to test and push FW updates that are recieved from the modems Mfr, i.e. NG in this case. NG can only do so much. Shame that some ISPs behave like this.
