I have Ethernet access but NO WIFI
I am having the same issues. I changed DNS Server Settings on one of my PCs to CLOUDFARE DNS SERVERS for both IPv4 and IPv6. I also disabled the UPnP option due to having to enter PortForwarding specifics into CAX80 settings.
I hope the issue is resolved/answered in this thread...I will update this generic post shortly.
For clarity: My issue is at least 3 times a day (sometimes as many as 8 times/24hours) it seems I have Ethernet access but NO WIFI. When I enter the CAX80 settings directly > ADVANCED > ADVANCED HOME > INTERNET PORT Window colored radial preceding the description will show Green if working/functional or "yellow" if not....Too often is NOT GREEN...forcing me to use the first window option of REBOOTING...this is a major issue for me due to being a Medical Doctor that allocates a lot of time with patients on line

A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. https://kb.netgear.com/22697/How-do-I-install-my-NETGEAR-router-using-the-router-web-interface
