RBK53s Router drops modem connection

The most current FW version is v2.5.1.8. Stable and working for me.

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 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 maynot 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. Save settings and reboot the router and satellite(s).

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

After 6 mo,the RBR50 router (part of the RBK53s package) has suddenly started dropping its connection several times a day. I either have to push its Sync button or when that doesn't work, power cycle it to get a connection again. Many times it will drop and it will resync itself after a few minutes without my pushing the sync button. I have not updated the firmware recently (v2.3.5.30), so I do not know what has triggered this behavior. The modem it's connected to is fine; I have not needed to power cycle it. 

 

Frustrating! Should I look at replacing it?
