If I am correct, you have been both, very interested and knowledgeable, about Wi-Fi related software on the 211. If you or anyone else has already, or gets the chance to, could you check out AirScanner Sniffer on your 210? http://www.airscanner.com/downloads/
I read about it on another site yesterday, and apparently it can be used to test the security, of your own network, as well as be used to retrieve network keys (only interested in seeing if it can capture my own keys of course).
I got into bed late last night and got right back out of bed, when I realized that I had finally got the program to work for a few minutes. I was walking around my house in the dark, felines following behind and my 211 making loud rapid beeping sounds (reminded of Ghostbusters for some reason) and a lot of data logs showing up in the program. Now I can’t seem to get it sniffing again……
Re: To David Hettel or anyone else: Wi-FI Sniffing
There is one application Cain & Abel (google to find the website) that will 'just' listen to the message traffic and retain "passwords" and "user id's" in accordance with predetermined filters. There is a Pocket PC as well as a regular XP (and of course *nix). Check out their website for details. I'm not sure the Pocket PC version is still hosted there, but it IS around. Nothing to do with network keys though.
