As you give so little information it's difficult to comment. However you have probably set the WEP or WPA key wrong. That is to say you have entered it wrong on the PC - different to the one that you set in the router. If you can't sort it out on the PC you'll need to connect to the router via an Ethernet cable to reset the wireless parameters again.
