I have RBR20 + 2 RBS20 setup, with firmware v2.5.1.16 on all of them. the system works fine since July 2020, but suddenly one of the satellite randomly disconnect/offine multiple time a day. I tried power on/off, reset, sync ... but it will work for a little then offline.
This is no movement of the router and satellites and they stay in same location for months. the other satellite rbs20 works fine (so far) and no issue.
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 or more is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite
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?
I swapped RBS locations and then move one to a higher spot and this time it worked - so far so good. Not sure why the location worked for the past 5 months and suddently not working but hope this time will last longer.
