CAX80 firmware V2.1.2.6 issues

Well Xfinity firmware push strikes again...

I have looked through the history of posts here and found last year the v2.1.1.4 caused a fuss too (here).  Well here I am waking up to being forced to use my phone hotspot.  What the heck just happened Xfinity??  I think my router has completely forgotten how to accept or assign IPv4 addresses??  I know that it was an ISP firmware push because the logs reported the update at ~4:30am local time before everything went crazy.  Even the little internet I can get is oddly half-baked.  (I double checked to make sure I wasn't pulling up cached sites too.) Could it be I can only access the ipv6 internet?

I seem to be in an eternal reset loop where 192.168.1.1 doesn't work but www.routerlogin.com is stuck in an endless reset loop.  I can't tell you how many times I have reset my password and security questions in the last 2 hours...

Anyone else having issues?  I also can't seem to get my CAX80 to factory reset either... that might be unrelated but who knows.

Good morning @ilikecerealtoo and thank you for reaching out to our Digital Care Team on our forums with your concerns. I'm sorry to about your router and connection issues but rest assured our team is here to help. How long have you been experiencing this issue? What troubleshooting steps have you attempted so far? With regards to your router since it is not Comcast equipment, have you attempted to contact the manufacturer to see if they have any additional insight?

FWIW, it may not be Comcast supplied equipment, but Comcast is still responsible for maintaining and upgrading the firmware for both the cable modem component, and the router component of customer owned combo gateway devices such as the CAX80.

Last Tuesday I spent 6hrs troubleshooting before everything was back up and running.  I had to flash back to v2.1.1.4 do a hard 30-30-30 reset then manually flash back up to v2.1.2.6.  What caught me up was the last "30" reset actually took more like 60 seconds for the lights to register the reset button was pressed on power-on.  As far as I know I am completely on my own here...

Netgear won't help me troubleshoot anything unless I pay for the extended warranty. (Nope!)  I can't even get in touch with any humans outside of the paywall. gg Netgear...

Comcast/Xfinity also won't help much because my hardware is both privately owned and Netgear-made.  I feel comfortable with that but if Xfinity is going to offer such minimal support why push out new firmware at all?  If I pay $400+ for my own hardware doesn't it make sense that I would maintain it myself?  Could there even be better communication when these firmware pushes are scheduled?  Tell me to update it and send me a private link to the ISP version of the firmware.

The issue for me was the onboard IPv4 DHCP server.  I have searched hard enough to find the DHCP server issue is a known issue.  Many high-end Netgear products have similar problems.  Some have reported that it triggers when their Netgear product reports a new firmware is available or after a new firmware is upgraded.  Others report the issue triggering randomly?  Has anyone else had this DHCP server problem with the CAX80?

Either way, both companies are happy to send me out to pasture while advertising I buy their (new) product if I want better support.  meh... I got it working but wish there was better support out there.

@ilikecerealtoo you could do a factory reset and see if that clears the issue. I’m not having this issue with the update to my cax80. It sucks because you do lose any customized configuration settings, but maybe the reset allows you to get back into the management console and reconfigure your settings.
