I had the same problem. My Apple iPod Touch could not connect to my new Linksys wireless WAG54G2 modem / router.

My other devices worked fine (PC with DLINK DWA-110 USB Wi-fi and HTC Magic phone - with Android OS).

Trying to get the iPod Touch to connect, on the router I tried all the security protocols and changing passcodes. Nothing worked.

THEN, I changed the WAG54G2 router from the default wifi channel of 11 to 9....and the problem was gone. Immediately.

It looks like the channel 11 on the Linksys WAG54G2 and the channel 11 on my Apple iPod Touch do not align closely enough to get connected.

This may also be true for other devices. Try another channel.
