Could not find any certificate to log on the network

Just formatted and installed XP Pro again. And thus it came up a new problem

I have a new D-Link DIR-615 router and a D-Link DWA-140 USB adapter. I installed the drive clean, and have 100% signal from the router, but no network. Always receive the message "Could not find any certificate to log on the network". Everything is really set up as it should, XP Pro SP1, (until I get online). 802.1x authentication is not checked. WPA-PSK is the AES / TKIP.

I hope someone can help me to solve this problem
Thank you for all your answers!

Connect to the router with cable and check under the Advanced if wifi protected setup is disabled.

Have you entered the correct encryption key and the encryption method?

Also if you look at the properties for the wireless card, I seem there are some settings in which to use the certificates in one of the tabs. You can see if you have something there, and in this case turn of ...
