Are you using IPv6?

Does the front of the RBR turn PINK when this happens?
What happens if you use ISP DNS?
RBR WAN set for DHCP or is it using PPPoE?

ISP DNS or assigned in router give the same result.
DHCP (doesn't use PPPoE).

See if issue still happens...I think some ONTs can cause some problems with Orbi systems. Not sure if NG has any fixes for this...
