XP Pro not saving wireless network settings

[TheReasonIFail]

I have an IBM ThinkPad T42 running Windows XP Pro w/ SP3 fully patched and all of a sudden it says it can't see wireless networks. I manually edited my network and it worked fine until I rebooted the PC, now even manually entering the network settings doesn't work.

Is there a way to reset the wireless settings similar to the reset of the TCP/IP stack?

You can try restarting the Wireless Zero Configuration service. However this may be disabled if you are using a program instead of Windows to manage your wireless. If this doesn't work, maybe try using the software for your NIC to do it instead.
