Ok, here's the problem. Me and my brother both have laptops, however mine is a more gaming based laptop, therefore better for me to be host of the LAN. However, the game decides, NOPENOPENOPE. If I try to be host, my brother can't even see that it is open. If he hosts I can see and join, however this causes lag spikes for him, and, until just a few hours ago, before I increased the ram for technic on his laptop, he would crash due to lag spikes. Help? A few notes: 1: Disabling both firewalls had no effect. 2 Connecting to a different wifi had no effect. 3 We are both in the same room.
