Turn OFF Protection Engine on the CAX80s web page and see if this helps:
NETGEAR Nighthawk - Protection Engine Feature FAQ | NETGEAR Communities
What channels are you using on the CAX80? Try 1 or 11 on 2.4Ghz and 40 or 48 on 5Ghz.
Is FW updated on the EAX80?
What is distances between the CAX80 and EAX80? 30 feet is starting distance or more.

Just wanted to say that I was having similar issues to OP with my CAX80 - woke up yesterday morning with no internet access on Wi-Fi OR Ethernet even though the connection status looked good in the modem dashboard. Called my ISP and everything looked good to them as well. After resetting the modem several times I was eventually able to get internet access through the Firefox browser but nothing else…which was super strange.
I disabled the Protection Engine feature like you suggested and it fixed everything! Now all my devices are connecting like normal. Thank you 🙏🏻
