Ruida was the first, but it would not be terrifically difficult to add LightBurn Bridge support for Trocen controllers as well, and that would solve the issue - The bridge uses TCP to communicate with LightBurn, and UDP to talk to the laser. We’ve set it up to allow different protocols. It’ll take some time to implement, but it’s on the agenda.
Aside from that, there’s nothing that’s really going to prevent packet loss. You could try using a PowerLine adapter - That would let you connect the PC to the router through your power lines, and I’ve never had drops using them.
