CM2000, 1000, etc firmware update needed for Spectrum IPv6
Hello, For many months all user-owned CM series Netgear cable modems are unable to retrieve IPv6 leases. They previously worked without issue. There are numerous mentions on DSL Reports and als...
Netgear sends spectrum updates but spectrum doesn't necessarily deploy them.
You can compare your version to what version spectrum has approved and other ISP's have.
But one thing I've noticed is that it tends to be the router with IPv6 issues versus the modem.
sounds like Spectrum just trying to pass the buck.
Thank you for the reply.
As I mentioned, multiple people on the Spectrum network report the issue specific to Netgear modems. In my case my router and infrastructure are all Ubiquiti - UniFi and have full IPv6 working via various tunnel brokers and locally on my LAN. Also of note is the listed firmware at the link you provided is not, in fact, the latest deployed to Spectrum devices. The latest on my device is V1.01.08. Suggesting that table is not maintained. My contacts at Spectrum have cited the need for a certification process to be engaged in by Netgear. This isn't a tech support request but a vendor issue between the ISP and vendor we've chosen for our device. Customers are switching to Motorola and Hiltron to remediate the issue. I wanted to try and get a response from Netgear before I do the same. Again, appreciate the offer of help, but this isn't a router issue. It's a network policy issue with Spectrum and they cite firmware as the reason. I'm unaware of any CVE or other issue that would require them to adopt such a policy, but it's what my contacts there have explained. I've looked on NANOG for a Netgear contact but sadly this forum appears to be the best communication channel and it appears to be managed mostly by non-Netgear staff like yourself. While helpful, it's not what's needed here.
Spectrum can always contact netgear if they're saying its a netgear issue.
Again, netgear sends the files but spectrum actually has to certify it.
You can potentially try this form as well.
Appreciate the link. Spectrum is not Netgear's customer. We are. They are not incentivized to contact them as they provide their own gear. Sadly it's not as robust as the Netgear equipment.
NG develops and does some internal testing on there side. NG then sends these builds to ISP for there internal testing and certification. Its up to the ISP to test and certify that the FW is good for there network. Once this is done its up to the ISP to push it out to users modems. Some ISPs won't update user owned modems. That's there policy if they have that.
If the ISP finds issues during there testing and certification, it would be up to the ISP to communicate this with NG or any other modem Mfr and work out the problems between them. I would not presume that ISP may or may not be incentivized. Hard to know what the ISPs and modem Mfrs have in place for working and developing FW for user owned modems.
