Cox says they can't update my modem's firmware.
Modem Firmware for Netgear AC1200 Model C6220 has version V1.02.01 but per Netgear it needs to be V1.01.26 for Cox. Netgear says "Firmware upgrades are pushed down by your ISP." Cox tech support supervisor "Brian" said there is nothing he can do to update the firmware. This firmware update is my last attempt and resolving our intermittent WiFi connections before going back to CenturyLink (blah). Anyone know how to update this modem firmware?

You're caught between a rock and a hard place. netgear can't update the firmware. They can supply the file to cox but its up to cox to send it to the modem/router. Its one of the main reasons to buy a modem seperate from a router.
Your wifi issue? more details might help.
are you having issues on 2.4ghz? on 5ghz? What exactly is going on?
How large is your home?
What are the interior walls made of?
If you do a scan, how many 2.4ghz signals do you pick up? and 5ghz?
And this is actually the forum for your device:

We are having intermittent WiFi connection issues with our Apple and Roku devices on both 2.4GHz and 5GHz bands where a couple times a day we can't access the internet. Restarting the devices or router seems to help but it's a daily occurance since we've had COX service and using this modem router.
We have a 3000 sqft home with dry wall interior along with a repeater for one end of the house but the issues occur throughout the house.
There are 11 devices on our network, three on the 2.4GHz band and 8 on the 5GHz band with signal strengths from -22 to -86 RSSI (most at around -70).
Wireless channel set to AUTO for 2.4GHz and channel 157 for 5GHz band. During a scan, the modem rounter detects eight 2.4GHz networks and five 5GHz networks.
If you log into the C6220 and get a screen snip of the cable connections page and the logs, that can help check if its the signal back to Cox.
Do you have the issue if you don't use the extender?
