not to be a noob, but i'm bumping this thread....somebody that can play online, plz tell me your firmware version for a WRT54GS linksys router...if i try that and it doesnt work....idk

The router shouldn't be the problem. It's either:
1. You don't have the required Qi.
2. You are trying to make a new server and it is full.
3. The server is to packed.

sry but i am blue belt and i try semipro servers like im supposed to and they dont work.
when i make a server it does the exact same thing.
and i make sure to look at how many ppl r in the server before i go in....im pretty sure it is the router.
i dont know if ive said this yet, but i can play multiplayer at my friends house and the library so yeah.....

i dont know if this was an update or anything, but i can play online now. It would prolly be a good idea to close the thread so yeah.

Oh, linksys routers are not good, alot of times you need a modem.
