Ok, I'm back to this issue. Not clear as how to change or override the router IP address. If I can move it to temporarily 192.168.1.1, then perhaps I could connect to the NAS device and reconfigure...

Sorry, error in my prior reply. I meant to say I can't access the NAS device.

If can't change the IP address of the router (since I can't access it), how would I change the IP range on the A7 router?

The NAS has an IP address of 192.168.1.12. All the Archer A7 attached devices are in the 192.168.0.x subnet. This is likely the problem. How do I change the NAS address?

My new Archer A7 router doesn't recognized the wired connection from a Netgear ReadyNAS Duo. This NAS device connected with my prior Netgear router. All my other devices connected easily to the A7...
