    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 segment

    Send 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.
