When I first received my laser it was out of ‘range’ of any of my wired networks. Way too far away for a long cable thought the house. So I connected directly with my pc. I set the IP to something unique in my local network and set the lasers gateway to my computers IP. Connected right up… Kind of a kludge… but it was quick… 
I have since purchased $25 router that I’m using as a wireless bridge. So it’s on the network now even at distance.
Take care
P.S. tried to answer a question here, but the resultant reply is questionable. I dropped his lightburn file back after the fix, but it isn’t showing up right. Might be confusing… Thanks.
