Random disconnect daily

Hi I do have about 2 to 4 short disconnects everyday (as measured by my Firewalla router).
They last about 1 minute.

Equipment:

Modem = NETGEAR Nighthawk CM3000  

Router = Firewala Gold SE

Below  is my Cable Diagnostic file (MAC address redacted).

My router first report first "Failed DNS test" and then "cable disconnected" and vice-versa when the connection is up again.

CM status reports power level good and SNR good.

Am I missing something? Is the trouble with the modem signal or with my router?

Any help welcomed!

Regards
