Many of you may still be using Ethereal for obtaining packet traces of Wi-Fi networks.  About a year ago, Gerald Combs, Ethereal's lead developer, left his company and couldn’t keep the name "Ethereal." As a result, Gerald renamed the software "Wireshark" and has been supporting Wireshark since then. Instead of using Ethereal, which I don't believe is being supported anymore, I recommend downloading the latest version of Wireshark at www.wireshark.org. Wireshark is still free and provides the same (and better) functionality as Ethereal.
