Router Connectivity Issue

Hi Friends, Few days back I have purchased Compusa router, While wireless connection I am getting error message "Limited or no connectivity - You might not be able to access the internet or some network resources.This problem ocurred because the network did not assign a network address to the computer".....

I tried repair option but repair is not allowing to renew the IP address.

Can someone help me to resolve this issue. Pls let me know if I m missing somehting.

Thanks in advance.
