In case like this one sometimes it is best to reset the password then try to connect each of the devices.

The D Link 6 series router where good but a little tempermental at times. Also you could check the Dlink site for new firmware as from time to time manufacturers make improvements even after the product has been to market.

The DHCP on your router isn't working properly. You should perform a hard reset on the router by finding the reset button on it. Take a pen or other small pointy object find find a tiny hole on the router. Press and hold this for 20-30 seconds. This will reset to factory settings and the password to the router will also be reset to its normal default.

Reconfigure the router as if you had just bought it new and it should work properly this time

If that won't work it only means that it's already been changed you just reset the router by pressing the reset button for 30 seconds.

I'm assuming you're in USA. The FCC may be limiting the frequency range that the card can use.  Check out drivers for other locations to see if that helps.  Also see if you have current drivers.
