What is the best wireless scanner that will work on my Ipaq? I need to be able to find rogue devices that are in my network that I don't want. I at least want to detect 802.11b and anything beyond that is a plus.
Check out ministumbler. http://www.stumbler.net. We use it all the time with good results. It doesn't work with a cisco card so you'll need one of the supported ones.
