  <title>Dépannage du réseau sans fil</title>

  <subtitle>Assurez-vous d'avoir des pilotes de périphériques fonctionnels installés</subtitle>

<!-- Needs links (see below) -->

  <p>À cette étape, vérifiez que vous pouvez obtenir des pilotes de périphérique fonctionnels pour votre adaptateur sans fil. Un <em>pilote de périphérique</em> est un petit logiciel qui indique à votre ordinateur comment faire fonctionner correctement ce périphérique. Même si l'adaptateur sans fil a été reconnu par l'ordinateur, il n'a peut-être pas de pilotes qui fonctionnent parfaitement. Il vous est possible de trouver différents pilotes qui soient fonctionnels avec votre adaptateur sans fil. Essayez ces différentes possibilités :</p>

  <list>
    <item>
      <p>Vérifiez que votre adaptateur sans fil figure sur la liste des périphériques pris en charge.</p>
      <p>Most Linux distributions keep a list of wireless devices that they
      have support for. Sometimes, these lists provide extra information on how
      to get the drivers for certain adapters working properly. Go to the list
      for your distribution (for example,
      <link href="https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported">Ubuntu</link>,
      <link href="https://wiki.archlinux.org/index.php/Wireless_network_configuration">Arch</link>,
      <link href="https://wireless.wiki.kernel.org/en/users/Drivers">Fedora</link> or
      <link href="http://en.opensuse.org/HCL:Network_(Wireless)">openSUSE</link>)
      and see if your make and model of wireless adapter is listed. You may be
      able to use some of the information there to get your wireless drivers
      working.</p>
    </item>
    <item>
      <p>Recherchez des pilotes propriétaires (binaires).</p>
      <p>Many Linux distributions only come with device drivers which are
      <em>free</em> and <em>open source</em>. This is because they cannot
      distribute drivers which are proprietary, or closed-source. If the
      correct driver for your wireless adapter is only available in a non-free,
      or “binary-only” version, it may not be installed by default. If this is
      the case, look on the wireless adapter manufacturer’s website to see if
      they have any Linux drivers.</p>
      <p>Quelques distributions Linux proposent un outil pour télécharger des pilotes restreints à votre place. Si c'est le cas avec votre distribution, utilisez-le pour trouver vos pilotes sans fil.</p>
    </item>
    <item>
      <p>Utilisez les pilotes Windows pour votre adaptateur.</p>
      <p>In general, you cannot use a device driver designed for one operating
      system (like Windows) on another operating system (like Linux). This is
      because they have different ways of handling devices. For wireless
      adapters, however, you can install a compatibility layer called
      <em>NDISwrapper</em> which lets you use some Windows wireless drivers on
      Linux. This is useful because wireless adapters almost always have
      Windows drivers available for them, whereas Linux drivers are sometimes
      not available. You can learn more about how to use NDISwrapper
      <link href="https://sourceforge.net/p/ndiswrapper/ndiswrapper/Main_Page/">here</link>.
      Note that not all wireless drivers can be used through NDISwrapper.</p>
    </item>
  </list>

  <p>Si aucune de ces options ne fonctionne, essayez un autre adaptateur sans fil pour résoudre le problème. Les adaptateurs USB sans fil sont relativement bon marché et se branchent sur n'importe quel ordinateur. Vérifiez néanmoins qu'il soit compatible avec votre distribution Linux avant d'en acheter un.</p>
