Networking is very confusing, I bought a hub thinking it was a router and spent about 2 hours trying to figure out why the heck my computers weren't sharing a connection with my dsl modem.
Now, my router doesn't allow me to play online games in which then after 20 minutes of surfing the web I found that I needed to open ports through the configuration screens, then I go there and there's a bunch of mumbo jumbo about trigger type trigger ports public ports public type, udp and tcp. Dear god help me, and I though html was hard.
Guess what? Now I have to find out how to open the ports without getting REALLY high pings in online games.
Anyways,
http://www.hardforums.com has a networking forum (scroll down) in which you can ask questions at, although they sometimes have maintenance stuff and they close the board for like 45 minutes.
