Even if you’re an avid user of some of the premium packet analysis tools out there, such as Savvius’ excellent Omnipeek, every so often most people will be opening up the free Wireshark to look at a capture.
Unfortunately the default view included with Wireshark is very poorly suited to 802.11 packet analysis:
I recently attended a Certified Wireless Design Professional (CWDP) course, host by Spectrotech and trained by Wi-Fi expert and CWNE #1, Devin Akin.
One of the highlights of a week of intense training was an exercise on the last day. Devin asked the class to break into teams and each team was to come up with as many ways to increase Wi-Fi airtime as possible. We would then reconvene and deliver our results one-at-a-time in round-robin fashion. If one team gave an answer, the others couldn’t give the answer and had to come up with their own, until all responses had been delivered. The team with the most answers would be declared the winner.
Well, with so many great professionals in each team, it’s no wonder that Devin managed to fill the whiteboard and then had to declare a tie.
