Cannot Use Wifi On One Computer

I have a TP-Link WR1043ND router connected to a cable modem. It works fine, except on the laptop I initially used to configure the router with the help of the CD-Rom Tp-Link provides. I obviously used wired connection to configure the router. The laptop I did that with works perfectly fine when connected to the router with a cable, but is unable to access the internet through Wi-Fi (even though it sees and connect to the Wi-Fi network). All other computers I have use the Wi-Fi Network to connect to the Internet without problem. Help, please
