I spent 4 hours on the phone with Netgear and I wish that COX would leave my router alone and allow me to administer it. I am an MCSE and I know what I'm doing.

It was the firmware update Cox sent to my device that cause my network connection to be under attack, drop connection and unable to work for the entire day.

At first, I thought it was updates from the devices and looked for a patch. When I finally decided to log into the router again and view the logs that I discovered the attack and reason for the dropping of network. These attacks caused devices on your network to be attacked and drop every 3-5 minutes. Logs were and can be provided.

What Netgear suggested was on the CX30 device was DOWNGRADE THE SOFTWARE that Cox pushed to my device. It's also recommended, but Cox will not do this for residential customer is to release and renew your IP with a new one. So turn the router off for over 24 hours so that DHCP will assign a new IP to your network.

I'll be paying daily attention to my router. If you update it again, I will downgrade it again. However, by your doing this you are causing two household members loss of work. 

Here's the FIX:  If you have a Netgear device go to netgears website ,under support ,and look for your model and firmware, download the correct version and follow the instructions. Nothing but this corrects the issue.

    Cox doesn't touch your router, unless you are on a WiFi modem, and then ONLY to push a firmware to the modem.  It appears you have a WiFi modem, and Cox will push the latest APPROVED firmware to the modem. If you had a newer firmware and it hasn't yet passed Docsis Engineering testing, then yes, you would be downgraded to the latest approved firmware. 

    As for your SETTINGS on the router, unless the firmware removed, or added a setting not on the previous firmware, then yes, your settings may be changed by the firmware push. Other than that, your other settings are not altered. 

    BTW, Having your MCSE doesn't impress, and was unnecessary to throw in there.

      Me? I am only A+ certified(which I know means nothing). Everything else is either obtained through training by Cox or self taught.

       I agree that the firmware of a gateway(modem/router combo) is usually controlled/loaded by the ISP. However it seems there is a override built into the CAX30. See page 64 of manual for confirmation. Seems the firmware is from 11/30/2022.

        It appears the router firmware and the modem firmware are separate entities in this device. If it's actually one and the same, and the user updates to a firmware not compatible with the Cox network, it could cause problems for MANY people. Further investigation with Netgear indicates the router firmware AND the modem firmware are separate, so no matter WHAT modem firmware updates COX was to provide, it would have zero bearing on the router firmware OR it's settings. 

        BTW, funny story, when I first took my A+ cert exam, at ECPI, they called me in to re-take it. I paid for and took the test, and never took any classes. It seems I aced the test, and they thought I MAY have cheated, so they called me back in to retake under the eyes of a test examiner. I aced it a second time, and they apologized for thinking I hid the answers somewhere on my body to take the test.
