This section is more of a general primer. I will not attempt at this time to add information about problem solving if this doesn't work. If you need assistance of that type, check out the readme.txt file that came with the game. Or check out Jediknight.net's Multiplayer Guide .
Lets start out by saying the following.
At this time Jedi Knight does not have dedicated server support. This means there are no real permament servers on the net. The host must be in the game. This also limits the size of the game to a smaller number of players. More players will mean more latency in the game.
