I experienced this problem as well, for about 1.5 weeks. Every 30 or 60 minutes, there would be a 5–7 second drop. I narrowed it down to the leg of the network between the Orbi and my cable modem. The red exclamation points show the times when there was a lost connection between the two:

I was about to buy a new cable modem and test that out, when I wondered whether there was new Orbi firmware to try first. I upgraded to 2.7.4.24 and the issue stopped. No idea if it was the firmware itself or if it was whatever reset the device does while applying the new firmware... but glad to be back to normal!

What Orbi model do you have? 

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

What CAT# lan cable is being used between the Orbi and ISP modem? 

Are you wired or wireless with your audio device with the Orbi system?
