Help on quake online multiplayer

Okay I am a complete noob when it comes to this so please if someone just sends me files I WILL NOT KNOW WHAT TO DO...so please explain :)
So I have quake 1 on my psp and it is the full game. I really want to play online on it but when i go to the multiplayer section it says no communications available and it wont give me the option of turning on infrastructure or ad hoc .Can someone please help me so I can play online? Also I have cfw 4.01 m33 and I use a mac if that has anything to do with what I need to do. Thanks :)

It gives me the option of adhoc or infrastructure but they wont do anything even with switch on it always just says off on both of them.

Anyone who can help??????aaannnyyyoonneee???
