Buffalo LS-WXL Windows 10?

Good morning,

I dug out something really old from the Windows Vista/Windows 7 era, namely a BuffLo LinkStation LS-WXL. The thing still works, the hard drives are still working, etc.

Now I'm having some minor problems with the setup. The system is set up, but I can't access the NAS with my laptop (Windows 10 64-bit).

Despite the correct IP address I get this error:

What should I do now? The diagnosis doesn't help, of course; it says everything's fine.

Since the NAS was last in operation, we have changed our entire network: new router, new switch, new access points, etc.

Could that be the reason?
