Hello All,
This is a simple worksheet that was designed to give Wi-Fi Engineers new to protocol analysis an opportunity to create filters for use with Wireshark.Hope this helps someone.

That rocks, thanks James!
Here’s another cool Apple tidbit:
Apple Channel Utility Test
Client induced channel saturation
Within a terminal window:To generate traffic on a WiFi interface, pick an available IP on the network.
Set a static arp entry for a fake host on the same network. You may be required to use sudo for the arp command.
arp -s 10.0.1.199 ab:cd:22:22:22:22
! mac is arbitrary
! IP should be on same segmentSend a bunch of traffic out the interface
cat /dev/random | nc -u 10.0.1.199 22
! include port # after ip address
Control-C to quit
Very nice, James! I especially like the blank cheat-sheet that you fill out as you make discoveries. The self-paced exercises are well thought out for beginners. Exercises 5 & 6 are the basis for determining the level of collisions occurring on the WLAN, and could be filtered further to show the amount of collisions per channel or device.
