====== Introduction ======

**IMPORTANT:**
  *Please read and understand the following prior to using this page: [[compatible_cards|Tutorial: Is My Wireless Card Compatible?]]
  * Microsoft Windows and all variants are **NOT** officially supported at this point in time.
  * See this [[faq#what_is_the_best_wireless_card_to_buy|FAQ entry]] if your question is "[[faq#what_is_the_best_wireless_card_to_buy|What is the best wireless card to buy?]]".


This section deals with a three related areas:

  *Compatibility of chipsets to the aircrack-ng suite
  *Which drivers are required for each type of chipset and operating system
  *Which wireless cards are known to work with the aircrack-ng suite

====== Determine the chipset ======
There are two manufacturers involved with wireless cards. The first is the brand of the card itself.  Examples of card manufacturers are Netgear, Ubiquiti , Linksys and D-Link. There are many, many manufacturers beyond the examples give here.

The second manufacturer is who makes the wireless chipset within the card. This is the most important company to know.  Unfortunately, it is sometimes the hardest to determine. This is because card manufacturers generally don't want to reveal what they use inside their card. However, for our purposes, it is critical to know the wireless chipset manufacturer. Knowing the wireless chipset manufacturer allows you to determine which operating systems are supported, software drivers you need and what limitations are associated with them. The [[compatibility_drivers#compatibility|compatibility]] section describes the operating systems supported and limitations by chipset.

You first need to determine what wireless chipset your card uses. This can be done by one or more of these techniques:

  *Search the internet for "<your card model> chipset" or "<your card model> linux". Quite often you can find references to what chipset your card uses and/or other people's experiences.
  *Search the [[http://forum.aircrack-ng.org/|Forum]]
  *You may also have a look at windows driver file names, it's often the name of the chipset or the driver to use.
  *Check later in this page for cards known to work with aircrack-ng
  *Check the card manufacturers page. Sometimes they say what chipset they use.
  *Have a look at **lspci -vv** output for descriptions, PCI id and kernel modules used.
  *Locate the [[http://pictures.aircrack-ng.org/fcc_id3.jpg|FCC ID]] of your device. Enter the information into [[http://transition.fcc.gov/oet/ea/fccid/|FCC Website]] and then browse the internal photos of the device.

\\
Here are some other resources to assist you in determine what chipset you have:

  * Linux-wireless has 3 pages depending on the device type: [[http://wireless.kernel.org/en/users/Devices/USB|USB]], [[http://wireless.kernel.org/en/users/Devices/PCI|PCI/PCI Express/MiniPCI/MiniPCI Express/Express Card/Cardbus]] and the old [[http://wireless.kernel.org/en/users/Devices/PCMCIA|PCMCIA]]
  * [[http://madwifi-project.org/wiki/Compatibility|Madwifi compatibility list]]
  * [[http://linux-wless.passys.nl/|Wireless Adapter Chipset Directory]] nearly the best resource for this kind of information
  * [[http://atheros.rapla.net/|Atheros chipsets based wireless 802.11a/b/g devices]] only Atheros-based cards
  * [[http://www.seattlewireless.net/index.cgi/HardwareComparison|Hardware Comparison]] with a lot of details.
  * [[http://s2p.de/bin/view/Sysadmin/ListeChipsatz|Overview]] and details about wireless adapters
  * [[http://www.backtrack-linux.org/wiki/index.php/Wireless_Drivers|BackTrack's old wiki]] outdated but may still contain relevant information

====== Determine the driver ======
Once you have determined the chipset, check the [[compatibility_drivers#drivers|driver]] section for which software driver you need. Software drivers connect the operating system to the hardware. The drivers are different for each operating system. There are also notes regarding limitations.

If you are deciding on which card to purchase, check the "[[compatibility_drivers#which_is_the_best_card_to_buy|Which is the best card to buy?]]" section on this page. There are many considerations that should go into your purchase decision:

  *Hardware compatibility with your existing equipment.
  *Price and availability of the card.
  *Availability of software drivers for your particular operating system and intended use of the software.
  *How active is development for the software drivers you need.
  *How much peer support and documentation is available for the card and software drivers.

It is not an easy decision to make. By considering these factors, it will help you make a more informed decision on what to purchase.
