Don't ask me why but Free-ed.net has free education available over the Internet. The courses are a little dated -- for instance they don't have anything on Windows XP or even Windows 2000 but they do have Windows NT education. Their IT course catalog is here.
Don't know if it's because I run the Orinoco Client Manager (but it still didn't work when I killed the Orinoco S/W) or what. Supposedly my card and my access point are both supported. Anyway, it looks like it'd be some good software but I can't evaluate it!
The new PCMag.com Wireless Center has a free utility called WiNc from Cirond that includes some of the functionality of NetStumbler and can also function as a replacement for WinXP's wireless connection manager. Check out Cirond's supported hardware list before trying out the utility. Also note that you must get it from the PCMag.com site within the next two weeks and not from the Cirond site. After two weeks the program costs $20. I think that means picking it up from PCMag.com will keep it free forever. You can find more about it and download the program here). There are versions for PocketPC 2002 and 2003, too.
The utilities that come with the Orinoco card are pretty good -- it can scan for access but it doesn't record -- and if you don't have an Orinoco, you're SOL.
Got a note from them yesterday about the launch of their new Wireless Center. It's not exactly Wi-Fi News but it's not a bad site.
Woody's Office Watch has a good rundown in his September 4th issue. He explains the issues and the implications. If you don't subscribe to his Office and Windows newsletters then you're missing some really good information.
