As jrfaust mentioned, the autoconfig address indicates that your computer isn't able to find a network or acquire an IP address. You mentioned that you've got other machines on the network...if those are using wireless successfully then we can probably safely say that it's this particular laptop. If so, then I would update the driver for the wireless adapter on that laptop as jrfaust suggested. As he also suggested, it wouldn't hurt to update the firmware of your access point.
If, on the other hand, the other computers are not connecting wirelessly, but are connecting successfully via wire (an ethernet cable) it would still either be an issue with your laptop's wireless adapter or the access point and the remedy would be the same: update the wireless adapter's driver and update the firmware on your access point. This second scenario would simply draw more attention to the possibility that something's wrong with the wireless capability of the access point.
Good luck!
