Now Spectrum has updated the CM3000 to version 6.01.03 - they refuse to roll it back

All this is on the ISP. Got word that the ISP has corrected this on there side. CM3000 modems should be good now. Please contact the ISP for continued help and information regarding this.

Good Luck.

Here is the reply we're getting from Spectrum. One of you is wrong!!!!! Either way you and Spectrum need to get together and set this fixed instead of leaving your customers with a $300 piece of garbage boat anchor Telling us that we don't matter to either one of you.

All -

We reached out to our engineering and communications teams and were able to get clarification on this issue.

While firmware updates are generally tested on our network and sometimes pushed by the ISP, the Netgear CM3000, which supports symmetrical speeds, has been whitelisted and firmware updates are pushed directly to the consumer from Netgear. You will need to contact Netgear directly for a resolution.

A workaround until Netgear resolves the issue would be to use a non impacted, approved modem or you can use a Spectrum provided modem, free of charge. Spectrum provided modems can be obtained by visiting your local Spectrum Store.

Please let us know if you have additional questions.

All users having the CM3000 modem with v6 FW need to tell the ISP to roll back the FW to prior working FW. Only ISPs can effect this revert in FW. CC/XF has already rolled users back. Make contact with NG support in regards to let them know your situation. NG has already been working with most ISPs regarding this. 

Nothing further can be done here in the forums. 

Good Luck. 

Having this exact issue with my CM3000 where it continuously reboots and never stays on longer than a minute. Reason is the firmware of course. Both sides are pointing at each other. Without a fix in sight I’ll probably have to return my Nighthawk CM3000 to BestBuy for a different brand just to get my service back running. Netgear says it’s their firmware and it should be fixed in 24-48 hours. Heard someone has been having this issue since the 19th and it’s now the 24th…

Same issue with my modem and cox, had 5 techs on site they replaced everything inside  and outside my home, made a FCC complaint with cox they replaced a bunch of stuff on the street as well as the hub and still having the same problems as so many other people (up stream not locking, constant disconnects, intermittent disconnects, and disconnects where nothing show up in the logs and everything shows good connection but have no internet)  i really wish i could have returned this modem at this point, i bought it back in may it worked for about 20 days and than the problem's started when they pushed this firmware. and here we all are with a 300$ piece of useless equipment. kind of crazy this has started 3 months ago and netgear hasn't really done anything to fix this. 

Hello:

Thought I would add to the issue regarding Cox Cable.

Have had same issue since Cox updated the CM3000 to version 6.01.03, likely in May.  Have had 4 Cox service calls and last one finally advised either modem itself or bad firmware.  He did advise he doubted Cox had ability to do firmware rollback, as had never heard of that happening.  He advised if I got a new CM3000, unless the problem version had been suspended by Cox, the new modem would likely get immediately updated as part of the provisioning process.  His only recommendation was to wait till next firmware update and see if fixed issues.

That is DOA; so likely giving it another week or so to see if Cox Cable initiates a rollback or will just buy Arris S34 and be done with this nonsense. 

Find it hard to believe the firmware issue made it past both NETGEAR and Cox.  Have usually had good luck with NETGEAR as also have Orbi 972 and it has been great.

Thanks
