Is RBK 50 still having problem with backhaul

My friends system has been up since day one of installation:

https://community.netgear.com/t5/Orbi/Orbi-firmware-update-v2-1-4-16-availability/m-p/1592753/highlight/true#M34020

What FW is currently loaded?
What is the Mfr and model# of the ISP modem the NG router is connected too?
Is the Orbi system operating in Router or AP mode?
What is the Mfr and model# of the ethernet switch if one is in the configuration.

For wired back haul:
Set up IP address reservations for each satellite and devices on the router as you add them to the router. The satellites need to be set up via wireless first. Then connect 1 satellite at a time to the ethernet LAN cable. Wait 5 minutes and the top led on the satellite should turn on BLUE. Set up an IP address reservation for the 1st satellite. Continue to do the same thing for the 2nd satellite. Then follow up with your devices.

Can anyone confirm that RBK50 works good with backhaul without any disconnecting.

Ahmed92 Did you mean to ask about wired backhaul? Or backhaul in general?
