Can't join any online games on CoD:WaW

[Stitch]

This has been happening for quite a while now. Everytime I try to join any type of online game I can never get in any games. I've left it for ages one time and I still didn't get in one and sometimes it just puts me in a game on my own and says waiting for 5 players. I've tried all the games modes and co-op.

On CoD4 it doesn't load the bit where you choose the game modes. Nothing like this happens on any game which isn't CoD. Has anyone got an idea why this is happening?
