Wireless networks not detected

Laptop23 was the last of the three laptops that the gaming teens screwed up. It would not connect to the wireless network, even though the bubble popped out of the system tray that says "one or more wireless networks are in range." When I clicked on the bubble, XP said no wireless networks were detected. The hardware was okay, because when I rebooted it with an Ubuntu LiveCD, it worked fine. After several dead ends, the search term "wireless networks not detected windows xp" turned up the following suggestion:

=========
TCP/IP stack repair options for use with Windows XP with SP2.

Start, Run, CMD to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reboot the machine.
========

And it worked!
