NAS visible to only some computers on network
I’m unable to access my Synology NAS drive from three computers on our home network. I cannot tell if the problem lies with the Synology NAS, our router, or the computers in question.
Here is the relevant information:
– Synology NAS is connected to an Orbi Satellite, which communicates with the main Orbi Router (RBR50). The home router address is 10.0.0.1, and the drive is 10.0.0.26 (IP is reserved for it).
– All devices on the network can connect to the NAS apart from these three computers.
– The three computers that cannot see the NAS cannot even ping it at all. Synology Assistant will not find it. HOWEVER: find.synology.com will locate it when run on these machines. They will then be unable to connect to it. It’s like any connection to the drive is being completely blocked on these machines.
– The problem began quite recently, but I cannot say why. I thought the cause might be an MacOS upgrade to something like Ventura 13.3.5 (a), but that only happened on two of the affected machines. The third is very old and running an older version of OSX.
Is it possible that the Orbi router is somehow blocking just these devices from connecting to the NAS? Why would that be?

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?Is seem you have a router infront of the RBR router if the RBR is currently using 10.0.0.x: This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop
Try option #2 first...What happens if you turn OFF the RBS and connect everything to the RBR?
> What Firmware version is currently loaded?
V2.7.4.24

The router is from a German ISP, Pyür. Model number: "CH746CE"
I have disabled the Wifi networks that ISP router/modem produces. However, I don't believe I changed any other settings on the modem.
Any advice on how to perform (1) or (2) that you recommended?
Might consider updating FW:
Contact the ISP on how to configure there hardware. I'd try option #2 first.
