LAN glitchy.

[Mega_Creeper_77]

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.
