If you have a Dell computer this should work (not sure if it works on others as well?):
Turning off Dell Wireless Utility: A message appears stating that Windows is not configured to handle the wireless connection, and to activate the Wireless Zero Config service. This may be due to a pre-existing Dell wireless utility handling the wireless connections. To turn this utility off, do the following:
Right click on the Dell Wireless Utility, located in the System tray, represented by several green bars. (open utility)
Click on the "Wireless Networks" tab.
Uncheck the "Let this tool manage your wireless settings" checkbox.
Click Apply then OK.
The Windows Zero Configuration service should now take over handling the wireless connections.
Hope that helps!
