Here's why we don't recommend routers; many of them provide traffic management or bandwidth profiling to optimize the network. Some units detect the Pro DJ Link data as garbage and try to block it. Your three choices:
- try and whitelist the MAC addresses of the XDJ-RX and your computer
- disable all traffic management and security features for your INTERNAL network (some allow you to leave these active for external traffic)
- use a different router or more simply, a network switch
