Hi
@david_c
From the above information, it does look like your NVR is currently on a different IP range (192.168.1.xxx) to your new router (192.168.0.xxx).
To get the NVR onto this new IP range, you need to select the NVR from the SADP list and this should bring up a box on the right of the SADP window that will let you modify details of the NVR.
Once you have this modify window open, you need to tick the 'Enable DHCP' box, enter your NVR password at the bottom, and click Modify.
After the change has been saved, if click 'Refresh' the SADP list should update with the NVR now assigned a 192.168.0.xxx IP address which is now the address you will use to access the NVR.
If the NVR has successfully been assigned a new IP address, you can go back into the modify window, disable DHCP, enter your NVR password, and click Modify.
Disabling DHCP after the IP address has changed will keep the NVRs IP address fixed to the one that was assigned when DHCP was enabled.
