What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials when wirelessly connected.

 

What happens if you use just 1 RBS with the RBR? 

 

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

My house is a 2 story, approx 4000sqft.  I have the router upstairs in the middle of the house and both satellites downstairs on opposite ends of the house.  Below are the various backhaul tests that contradict one another:

 

Web Interface of Router:
 
Always show "good". (see attachements)
 
Smartphone Application Interface:
Toggles from all green to both satellites orange or red (see attachement)
 
WiFi Commander:
Clearly shows disconnects from both satellites and these correspond with what I see in the app, although the web interface never shows the drops (assuming because of the short duration).
 
Telnet interface backhaul stats:
root@Orbi-Office:/# wlanconfig ath2 list stat
ADDR AID CHAN TXRATE RXRATE RSSI MINRSSI MAXRSSI IDLE TXSEQ RXSEQ CAPS ACAPS ERP STATE MAXRATE(DOT11) HTCAPS ASSOCTIME IEs MODE PSMODE

You can clearly see that both satellites are about -67dBi.
 
I've moved satellites all over the place to find the best location.  I have done multiple factory resets.  I've gone through the backhaul sync process multiple times.  I just upgraded to 2.5.3.50.
 
I could use some ideas as I am fresh out. Thanks is advance!

    I've used the telnet interface 2 properly space my satellites away from the router while maintaining a -65 to -67dbm. So I don't think they are too close not do I think they are too far away. I would estimate that each node is about 30' away from the router.

    I live on a 3 acre lot and while I can see one neighbor's SSID, they signal strength is -80dbm so I don't think channel overlap with my neighbors are the issue.

    I have the 2.4GHz set manually to channel 6 and the 5GHz set to channel 44.

    Using WiFi analyzer, I can verify that those are the best channels and that there isn't a bunch of rogue ssids within range causing problems.

    What's interesting is that the router drops the connection to all satellites at the same time, so I'm thinking I may have a hardware issue.

    I have tried it with just one satellite but don't recall if I had the same drops. I'll retest that idea and let you know the results.

    Thanks for the suggestion.

      You might as about an RMA...
