can't connect to router :(

[jhix]

i just recently bought a ipod touch and i tried connecting to the internet via router (Dlink DI-624). everytime i try to connect it says "Unable to join network". i tried everything from rebooting my router, disabling my security to manually typing in the ip subnet etc. somebody help me please!

Are you using the correct cases when putting in the network key? Make sure you press shift whenever there's a capital.

Is the router set to allow only known mac-addresses to join? Or perhaps its DHCP server has used up all its address range? See on the router log if it is recording the ipod's attempts to connect, and see what error is given there.
