  • Arrgggg!... It took me a while to get my CAX80 stable. It was running without issues for about 3 months. Last night Netgear PUSHED! this firmware update and now I have to re-authenticate to the router when it reboots. NOT CONVENIENT IF YOU ARE NOT AT HOME!!! The router should re-start itself with the existing configuration without assistance. After a reboot, a power cycle and a firmware update.

     

    Now after saving a new configuration with 2.1.4.2 and using it to restore the router... the LAN reservations and device names are lost. It's like they're not being saved to the configuration file. Yes, I have factory reset the router using the reset button in the back, using the Revert to factory settings "Erase" button on the GUI and using the  NVRAM Reset/Factory Reset process. And reconfigured from SCRATCH.

     

    Why was the option to disable automatic firmware updates removed? - If I can not get it to be stable again, I will try to find the time to research for a non-Netgear replacement. I'm likely going back to a separate (Combo) Modem and Router solution. The CAX80 is a flawed integrated solution if you happen to be away when a power failure, reboot or firmware update happens.

     

    If anyone has any recommendations for a good combo solution (I'm using Spectrum as an ISP), please let me know.

      What does it mean "I have to re-authenticate to the router when it reboots."

      I recommend doing a full on factory reset and setup from scratch then save off a new backup configuration to file.

        "What does it mean "I have to re-authenticate to the router when it reboots."

        RE-ENTER CREDENTIALS -> User ID, Password then Answer two questionnaire question and Continue. After the router reboots due to: Power Cycle, Reboot via GUI or FIRMWARE UPDATE!

         

        "I recommend doing a full on factory reset and setup from scratch then save off a new backup configuration to file."

        I did it in 3 ways multiple times as I mentioned in my post.

        "Yes, I have factory reset the router using the reset button in the back, using the Revert to factory settings "Erase" button on the GUI and using the NVRAM Reset/Factory Reset process. And reconfigured from SCRATCH."

    I am curious about the rationale for your statement:

     

    NOTE: For any users that were on the CAX80 beta project. DO NOT LOAD THIS VERSION FW!!!

     

    This is an honest fact finding mission as opposed to any argument or such. I also noticed an earlier note from you that stated firmware upgrade capability may be compromised by the engineering or beta release.

     

    My system may be unusual in that an RPi running Pihole serves as my local DHCP server. The RPi is also running Unbound, serving as my DNS server. Any issues related to those functions would almost certainly be different on my system.

     

    All of that said, when I noticed the official 2.1.4.2 release on the Netgear site I decided to load that in hope that something may have improved since the engineering release. The CAX80 web interface indicated that no update was available. I just assumed that was because the version numbers were the same and the Netgear firmware didn't know what to make of the engineering suffix.

     

    So - I downloaded 2.1.4.2 from Netgear and pointed the firmware update utility in the web interface to the file and it loaded.

    All is well. I haven't seen anything at all out of the ordinary. In fact Comcast must have solved some issues while I was out camping as I am finally warning free on the connection and getting the data rates I am paying for.

     

    Curious what the issue you have seen was? Is my house going to spontaneously combust tomorrow? Well - it may but it would be more likely due to the generator lockout being wired in.

     

    Anyhoo - what issue did you see?

      If you bought your CAX from a retail outlet or direct from NG, then you can proceed to update if you want too. NG found a problem with early beta units that some of us got that were using older boot code which wasn't included with newer version of FW thus caused the FW partition to be come read only. We could not upgrade or downgrade FW. This only effects users with these early beta units. Otherwise, all other units seen in retail production are not effected. The notice is for beta units that some users may have. They know who they are.

      FURRYe38,

      Does new firmware 2.1.5.2 cause problems with the early beta CAX80. Thank you.

        It should not. Mines loaded with it. 

        There was an issue with beta having older boot loader code that would cause a problem with newer FW. I helped test this out with mine and NG fixed it.
