Security Camera Connectivity Issue on G34

I recently upgraded my WIFI Router/Cable Modem to an Arris Surfboard G34.  It has been a challenge getting all my devices connected to say the least.  I’m down to my last device.  My Arlo security camera doesn’t seem to be recognizable using the G34.  I’ve  the Arlo instructions but I keep getting the same message no Arlo devices found on the network.  It worked fine on the previous wifi router using the same procedure.  The Arris manual gives instructions for computers and smart phones but not devices like this.  I’m open to suggestions.
