Wi-Fi (WLAN, IEEE 802.11)

Wi-Fi, or IEEE 802.11, is the standard for wireless LANs, or WLANs.

It is specified by [http://standards.ieee.org/getieee802/802.11.html various IEEE 802.11 specifications].

  • 802.11a 54MBit/s 5GHz
  • 802.11b 11MBit/s 2.4GHz
  • 802.11g 54MBit/s 2.4GHz

History

XXX - add a brief description of 802.11 history

Protocol dependencies

  • 802.11 is the lowest software layer, so it only depends on hardware.

Example traffic

XXX - Add example traffic here (as plain text or Ethereal screenshot).

Ethereal

The 802.11 dissector is fully functional.

Preference Settings

(XXX add links to preference settings affecting how 802.11 is dissected).

Example capture file

XXX - Add a simple example capture file. Keep it short, it's also a good idea to gzip it to make it even smaller, as Ethereal can open gzipped files automatically.

Display Filter

A complete list of 802.11 display filter fields can be found in the [http://www.ethereal.com/docs/dfref/w/wlan.html display filter reference]

  • Show only the 802.11-based traffic:

     wlan 

    Show only the 802.11-based traffic to and from 802.11 MAC address 08:00:08:15:ca:fe:

     wlan.addr==08.00.08.15.ca.fe 

Capture Filter

  • Capture only the 802.11-based traffic to and from 802.11 MAC address 08:00:08:15:ca:fe:

     wlan host 08:00:08:15:ca:fe
