This question already has an answer here:
Coming home for Christmas break, my little brother wants to play some minecraft with me, and I finally obliged. My laptop is wireless on the network, and his old family computer is wired, with no wireless connection available. When I try to host the lan server, he can't see it, but when he hosts the server, I can see it. Here's the problem though. Whenever I try to connect to his lan server, it times out, with the error of unable to connect. What can I do to fix this?
