How do I setup a wifi connection from my router to my iPod?

I've set the iPod to automatically go on the nearest network, and I've turned on the router, and it's picked up the wireless network, but how do I put in the password? Nothin comes up and there's no where to put it in. How do I do it?How do I setup a wifi connection from my router to my iPod?
Hi,



If you've set it up to auto find nearest network your on the right tracks, the thing is when you need to input the network key you have to double tab once youv'e selected the network you want.



I've done this a few times so anymore probs regarding this please mail me.



Thanks
