My Linksys router suddenly died and I replaced it with a Negtear AX12. Now one of my 818's is no longer visible on the network nor on Roon.

The 818 may have been on a static IP (10.xxx) that is now outside the range of the new router (192.xxx) as I moved from the US to Europe. Looking to change the IP of the ID41 to DHCP or to factory reset the 818.

HELP PLEASE
