Wi-Fi problem

hi there, i was wondering if anybody could help me out on the wi-fi problem im having on my ipod touch (which i just bought today).
i have a linksys WRT54GS v4 router.
the ipod seems to be connected to the router, however whenever i try loading up google i get a message ssaying "safari cant open the page because it cant find the server" i have tried taking off all security and changed it a few times and still no luck.
but on the other hand through the ipod i am able to connect to my router and go into the configurations..which is weird...

any suggestions will be much appreciated
thanks

 

i have tried renew lease quite a few times...and no i do not have a proxy...ive been trying to get this thing to work for the whole day now...and i havnt found any solutions to the problem i have when i looked at other forums etc

 

tried all the steps mentioned above and i still have the problem...maybe its a defective product?

i will have to take it to the apple store ASAP...

thanks for the help
