Every once in awhile, the LED on the XE200 satellite will flash RED and the Deco App will show that the unit is "offline" even though I'm using an ETHERNET Backhaul. Conversely, the unit behaves the same on a wireless Backhaul connection. My old X95 2-pack Deco did the same thing. I know it's not the wiring (new house pre-wired for CAT-6 ETHERNET when built)  because my previous MESH system - Netgear Orbi RBK 852, didn't act this way.

Any idea why this would be happening?
