RBR20 constant connection issues

[zhoux]

Since the update of the mobile phone orbi software, the network disconnection phenomenon often occurs, and it is necessary to turn off the instrument and reconnect the program almost every day. I hope to get an effective solution.

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

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try enabling Beamforming and MIMO(MIMO may or may not be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

Has a factory reset and setup from scratch been performed since last FW update?

Use a PC or laptop and web browser to make any changes to the RBR.

What is the model# of the ISP modem the RBR is connected too. 

You'll need a PC or laptop connected to the RBRs web pagr to make any changes. The Orbi app doesn't provide this kind of change feature.
