RBR850/RBS850 stops communicating at LAN side

Question

Since a couple of weeks, my Router (RBR850) and all connected satellites stop communicating to all LAN connected devices (either wired or wireless). There is no network traffic possible, even the wired devices cannot communicate with each other. The weird thing is that the RBR850 WAN side is connected and accessible with the ORBI app.

This happens every few days. There are only 2 ways to get is working again:

1) Power-cycle the rbr850

2) Connect to the ORBI app using 'access anywhere', and reboot the system.

The frustrated thing is that logging is unavailable since the ORBI is in accessible, and the log is cleared at reboot.

Any clue what causes this, how to troubleshoot, and mostly, how to solve this?

Setup: RBR850, 2 wired RBS850 + 1 wireless RBS850, fw:7.2.6.21_5.0.20

(Unfortunately just ran out of warranty 😞 )

Thank you!

Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. https://kb.netgear.com/22697/How-do-I-install-my-NETGEAR-router-using-the-router-web-interface
Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

I would power OFF the ISP modem for 1 minute. Factory reset the router and power it off. Power ON the ISP modem and let it sync. Then power ON the router and walk thru the setup wizard again using a wired PC and a web browser.
Press the back reset button for 15 seconds then release.
