I've lost my remote controls for my VU+ Ultimo 4K and VU+ Duo 4K SE boxes. I've been controlling the boxes via the OpenWebif interface where I just visit the the IP address of the box in my browser to access it. But after disconnecting stuff and reconnecting I assume the Ips have changed as I can no longer access the boxes. How can I find out the new IP addresses when I don't have the remote controls to go into the settings of the boxes to find out the IP addresses?
