If they’re both plugged into the LAN, then be very sure the router cannot assign the Ruida’s IP address to another device through DHCP. When that happens, both devices will respond to network traffic to their (duplicated) IP address, which will trash the data going to both of them.
The Ruida has very little error checking and tends to store damaged files without complaint or comment. Worse, the errors aren’t reproducible; the only hint is that a file stored in the Ruida will produce the same errors in the laser pattern every time.
