I have been using Lightburn Bridge without issue until recently. I now have no lightburn bridge found. I have to rescan the laser to rediscover it. This works every time but sometimes I need to rescan throughout the work day. Kind of annoying. I have recently upgraded my WIFI router and think maybe this is the issue? Maybe a settings issue with my Pi?
It shouldn’t matter with the Lightburn PI. The PI should connect, laser or no laser.
I’d be thinking signal strength at the PI…?
I’m not running Lightburn on a PI, I’m running Lightburn Bridge to send data to the Laser with my Lightburn software on my windows computer. Basically a Wi-Fi connection to my Laser from my computer. Unless I misunderstood your answer , which is entirely possible. 
Are you running the binary that Lightburn posts for the Lightburn PI bridge?
Lightburn isn’t really a product for the PI architecture…
You should be able to see the bridge even without a laser connected.
My Ruida is powered off, an arp-scan of my lan shows the bridge is still present on the lan. I happen to know this is it, as it’s the only mac address that ends in 8b.

Did you bind the bridges ip to it’s mac address in your router?
This would account for having to rescan for the laser.
