Can't see any wireless networks in XP

A program that Microsoft makes available called devcon (http://support.microsoft.com/kb/311272) let me confirm that the PCI card was still working.  You can issue a rescan through the program to probe your cards.  Soon enough, the wireless card showed up, but didn't show any wireless networks.  I then updated the wireless driver to the 11/2010 version, reset your TCP/IP stack (net sh reset), removed the Wireless Network Adapter, and then saved the ThinkVantage connection, and all of sudden things started working again.
