RBR50 Eth cable Connected Devices not accessable from Satellites

[angr]

I'm having an issue where my Synology NAS, attached via Ethernet cable to my RBR50 router is not properly accessible via the Orbi Satellites (RBS50/RBS40). 

When on my laptop and connected to the router, it works fine:

However, when connected to my Satellites, it doesn't...

However, when I'm connected to a Satellite via the same computer, I no longer get any connection:

The "funny" thing is that connectivity still works from a cable-connected devices on the Satellite, only WiFi connected clients seems to be affected, where routing is obviously not working properly. PING was just as example, no TCP protocols works.  

Does this seems familiar to anyone?  Anyone has a solution? 

This issue started with version V2.3.1.48, but is unfortunately still present also with FW V2.3.1.60. 

Furry - no "router reset" suggestion, please. 

Thanks!

As further explanation - I can reach other Orbi connected devices also when connected to the Satellites, and internet connectivity also works fine. It's the cable-attached NAS that is unreachable on Satellite-connected WiFi since v .48.

Is Daisy chain enabled? Try a disabling if it is.

Try a reset if you have not since updating.
