Learning Networks with Linux: Wi-Fi IEEE 802.11 (part II)
The anatomy of Wi-Fi (802.11) protocol is delineated. In the long run, this knowledge will be very useful if one wants to develop the Wi-Fi hacking tools of one’s own beyond just mastering how to use existing tools.
This post is a chapter of “Learning Networks with Linux” (see the full list).
The tables displayed below enumerate Wi-Fi frame types classified by the type values, their description, and how one can filter for each type with the aid of Wireshark (see also this post).
Let us take a look at what each frames does, along with the corresponding specific Wireshark filter. Notice that tools like airodump-ng (see also this post) and kismet can use these frames to get the key information for hacking the AP.
