CM1150V wont bind all upstream channels after upgade to firmware 2.02.03 (Partial service)
My service was working fine with 32 downstream 3 upstream and 1 OFDM channel locked under firmware 1.01 right after the upgrade to 2.02.03 the service is saying "partial service" and showing upsteam channels incorrectly locked.
The upstream channels are seeing the frequencies they need but not locking apparently? see attached screenshot
If I plug any other DOCSIS 3 or 3.1 modem into the same coax connection I get all 3 upstream channels locked on the same frequencies.
Is this a UI bug? are the channels locked or not? I have no upstream speed problems

I'm haing the same issue. Only one of the 4 upstream channels will lock. Using a Comcast provided modem, all channels lock without issue. Cabling was replace by L3 tech and all signals scanned. Currently had to swap back to a Comcase gateway. Hopefully, it's just a firmware issue and I can get the Netgear back in service. I tried a 2nd CM1150V and had the same issue
Yeah, I can put any other modem on the same line and it lockes to all 3 upstream channels perfectly and no T-3 or T-4 errors in the even log... plug in the CM1150V and upstream won't lock more then 1 channel, partial service and upstream light blinks... it worked perfecetly up until the modem upgreated to 2.02.03 immediatly (littearly after the firmware updated) after that the problem started.
Sometimes it will lock one channel then channel 2 will try to lock on the same frequency and even list it as the 2nd one's frequency which is wrong. Maybe that is their bug?
and I get constant T-3 and T-4 errors since the firmware upgrade, cable tech says signals and lines are perfect. on an Arris modem I don't see any of these T-3 and T-4 errors..
Contact the ISP and see if they can downgrade the FW. Tell them that the problem started after the recent FW update. The ISP should be able to fix this.
Comcast wont do that unless it's causing a major service disruption... and from everyone I've talked to "your internet still works" therefore it isn't one
ontop of that they basically try to guilt you with this problem into renting one of their crappy gateways instead
Well they will have to check this since its on there system and there resposible for good operation and maintaining FW. You can try contacting NG to see if they have any suggestions or if this is a known issue. You might try another same model cablemodem to see if the problem continues. Could be bad HW as well. Try a CM1100 modem and see if it does the same thing. If it does, then both NG and CC need to address this.
I got someone at a higher level to revert my modem to firmware version 1.01.07 and everything is working fine again... I have 32 downstream bonded, 3 upstream and 1 ODFM downstream bonded.
How do we report this firmware bug to netgear? because this is a pretty big problem
After firmware downgrade:

Point them to this forum thread as well for review.
I've been trying to but my serial number comes back as invalid when I try to register it
