CAX80 Newest Firmware Doesn't Work (2.1.4.2)

My home's Nighthawk CAX80 doesn't work on the newest firmware (2.1.4.2). Whenever it automatically updates to 2.1.4.2, nothing is able to connect. The WiFi signal is able to be seen on my devices, but nothing can connect to it. I have to reset the router and downgrade the firmware via Ethernet before the Ethernet connection goes out and the problem persists. 

 

This only became an issue when I had to upgrade the firmware from 2.1.3.5 to 2.1.3.7 in order for port forwarding to work properly (separate issue). However the issue then became that the router would automatically update to 2.1.4.2 every morning. 

 

The router is currently back on 2.1.3.5 and it didn't auto update this morning, but now I'm back to not being able to port forward. Is there a way to fix 2.1.3.5's port forward issue, stop automatic firmware updates on 2.1.3.7, or fix 2.1.4.2's connection issues? Thanks!

    Did you factory reset the modem and setup from scratch after v4.2 was loaded?

        Yes, I did a complete factory reset after the update. The device still has the issue after any reboot. Anything else you can think of that may help?
