Problems Setting Up A Wirless Network

I am having a lot of problems trying to get this configuration to work.

I Have a d-link dsl- g604t Router. It's connected to the PC Using Ethernet cable. The laptop it's just wireless.

I've ran the networking Setup Wizard on Windows XP With no luck of filesharing or anything over this type of network. I done this on both PC's can anybody help me?

PC<<<<ethernet<<<Router>>>>> Wireless>>>> Laptop

Can you go to the laptop and go to start > run > type "cmd" (without quotes) and then on the dos box type ipconfig /all and paste the results in here.

It sounds like the laptop isn't getting an IP from the router
