Old router died so just installed a new ASUS AX5400. Setting up everything went fine until it came time to get the NAS up on the new network (NAS is an ASUSTOR AS3302T - couple years old).

Plugged the NAS into the router via Ethernet to a LAN port. Router control panel sees the NAS, even has it named correctly. But I simply can not connect to the NAS via a browser nor the NAS control app. Noting that the new router has a completely different IP range: 192.168.50.2 up through .254. NAS had previously been assigned 192.168.1.42 on the old router. Neither the new IP nor the old allow me access to the NAS control panels. Tried manually re-assigning the NAS IP to the 'old' address, but that number is out of range.

Am I (as I suspect) missing something obvious?

You would need to manually set an IP address on your computer in that range of 192.168.1.??? and then you should be able to access the NAS on its old IP address.
Then change it's IP address to a new 192.168.50.??? preferably outside of the DHCP pool range, which you may need to adjust on the router.

And then switch your computer back to DHCP and you should now be able to access the NAS on its new IP address.

Are you using Wi-Fi? Perhaps your router is enforcing network isolation so Wi-Fi devices can't see other devices?

Sorry - replied without the quote. Yes, this is where I'm at right now. Not yet able to change the IP range but trying to figure that out

Tried both wifi and direct connected to the Mac. Still no joy ... which is very odd imho

It sounds like the NAS has a static IP of 192.168.1.42 rather than a DHCP reservation (although there may have been an unused reservation on the router as well)

Option A:

Change the DHCP scope on the router to be 192.168.1.0/24

Option B:

Configure a device with a static IP in the 192.168.1.0/24 range, connect to the NAS and change it's static IP

To those kind enough to offer suggestions … my inadequate skills led me to failure on changing the IP range, etc. I decided to bite the bullet and do a factory reset and rebuild.

Quick aside … my Asustor NAS documentation says that a soft reset is simply powering off and back on. Which I tried multiple times to no avail.

so I did a factory reset (pin in the reset hole). After a couple attempts it worked … sort of. It did the soft reset. NAS was suddenly available under the new IP address, all data and settings intact.

moral of the story … sometimes it’s just bloody black magic.
