    First read what microchip8 says.

     

    Then look into why you have "lost service".

     

    That almost certainly has nothing to do with DoS Attacks.

     

    My wifi vanishes (as in it is not listed as an option from any of my devices) but none of the lights on the modem change.

     

    To deal with this symptom, start with the usual troubleshooting. First move, apply the latest firmware to the router bit of your modem router.

     

    I have a CAX30S modem/router running firmware V2.1.6.2

     

    That's not a firmware version in Netgear's library for the CAX30S. Maybe they withdrew it.

    That directs you here:

     

    CAX30 Firmware Version 2.2.1.12 - NETGEAR Support

     

    For more help check the section for your hardware. This place is for routers. You own a "gateway".

    You  might find something useful there.

Please post a copy and paste of the modems connection status and event log page.

I have a CAX30S modem/router running firmware V2.1.6.2 and the logs show a large amount of DoS Attacks each day coming from my public IP.  (Attached is a screenshot of a recent batch).  I wouldn't be concerned but the time on the logs is six hours ahead of what the modem is set on and I have briefly lost service twice in the last few weeks. My wifi vanishes (as in it is not listed as an option from any of my devices) but none of the lights on the modem change.
