are you able to play online games with a router? I know for sure I cant host but can I join with it?

Yes, if you can host with the router than you can definatly join with it.

yeah well the problem is that I cant host

I'm pretty sure you can join with a router. I used to do it at home, and I think I just played a game with someone recently, and I just got one here at school. But at least if all fails for me, I'll plug directly into the computer. BUT if you can't hook up via IP or MSN on your router, http://www.kali.net will do the job. It's hell setting up for it but nuttin beats IPX games on a gaming network.
