CAX30 - xfinity network updates require a factory reset -

When xfinity sends out a network update my Netgear Router/modem stops working.  The xfinity signal into my home has been confirmed by xfinity technical service at my home.  The router shows a WIFI network but my PC and devices cannot connect to it.  I see "secure network no internet" and "Wi-Fi doesn't have a valid IP configuration" errors.  The only way to resolve this issue is to do a factory reset on the router. I have 40+ smart devices connected to my WIFI and resetting the WIFI network connections for each device is time consuming and frustrating.  I've had to do this factory reset about every 2-3 weeks for the last 7-8 months.  I'm to the point of renting the router from xfinity for the $14 per month and throwing the Netgear device in the garbage.  Is there a setting I can select to prevent this from occurring?  Thank you in advance.

Your CAX30 gateway (combination cable modem and Wi-Fi router) has separate firmware for the cable modem section and separate firmware for the Wi-Fi router section.  The cable modem section firmware is under control of your ISP.  The firmware for the Wi-Fi router section is under control of the end user.  What is the firmware version you have installed for the Wi-Fi router section?  The latest is not an answer.  Only a number will confirm the answer.

If you have done a reset for the entire device or only for the Wi-Fi router section and afterward configured the exact same SSID and password, your various IoT (Internet of Things) devices should connect automatically.  There are a lot of variables involved and it may not be 100%.

For reference, you can go to this link and determine the current firmware version for the cable modem section of your gateway.

For reference, you can go to this link and download the CAX30 user manual and look for the most recent firmware for the Wi-Fi router section.

If you decide you need to update the firmware on your Wi-Fi router section, strongly recommend the manual update method described in the link below.

Stay away from mobile applications or Wi-Fi connections for the firmware update process.
