NAS not visible when connected to RBS50 satellite

[OLOMIK]

Hi,

I have an RBR50 with two RBS50 satellites over wifi. A NAS (EverTech) is wired to the RBR50.

The satellites have good connection to the main.

Problem:

When my laptop is connected to a satellite, the NAS is not accessible and it is not visible in the Orbi UI.

I can however access the NAS admin interface through the IP address. 

What to do?

Does the NAS appear on the Attached Devices display when the laptop is connected to the router?

Is there any device on the Attached Devices display with the IP address of the NAS, but an unusual name or description?

- Actually it does not, even though the NAS is available when connected to the RBR. Odd as I see other devices 

- Further - the NAS has a reserved IP adress outside the DHCP IP address range, which is the same for the Satellites, printer, Sonos, AppleTV etc. All that are ON are visible except for the NAS...

Is there any device on the Attached Devices display with the IP address of the NAS, but an unusual name or description?

- Nope. NO device with the same IP address visible.

Connect your Netgear Orbi Satellite (RBS50) router to a mother device. not to copy the password from the examples, because come on, show some ingenuity.

Explored a bit more; looks even more strange to me. Anyone with an idea on 

• RBR50 with two RBS50, #1 wired and #2 wifi connected and both visible at all times.
• RBR50 static devices: NAS wired, printer and Sonos One via wifi.
  Printer and Sonos are visible, NAS is never visible, but is accessible when the laptop, phone is on RBR50.
• RBS50 #1 static devices: AppleTV wired, Sonos ZP100 wifi
  Both visible and accessible regardless from what Orbi the accessing device is connected to.
• RBS50 #2 static devices: Sonos ZP100
  Sonos never visible, but accessible.
