Netgear CAX80 Modem Router

Have Netgear CAX80 Modem Router I purchased. Had approximately 15 months. Power light is solid white-no others lit or blinking. Is disconnected from home network. Have powered off/on cked connections but situation is same. Did hard restart to factory settings but no changes. Determined not current software version but can’t update because it’s disconnected from network. Nothing seems to work.
