  <title>Risoluzione dei problemi relativi alle reti senza fili</title>

  <subtitle>Assicurarsi che siano installati driver funzionanti</subtitle>

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

  <p>In questo passaggio viene indicato come ottenere driver dispositivi funzionanti per il proprio adattatore WiFi. Un <em>driver dispositivo</em> è un componente software che indica al computer come far funzionare correttamente un dispositivo hardware. Anche se l'adattatore WiFi è stato riconosciuto dal computer, potrebbe non avere driver che funzionano. È possibile trovare differenti driver funzionanti per l'adattatore WiFi. Provare alcune delle opzioni che seguono:</p>

  <list>
    <item>
      <p>Check to see if your wireless adapter is on a list of supported
      devices.</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="http://linuxwireless.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>Look for restricted (binary) drivers.</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>Some Linux distributions have a tool that can download restricted
      drivers for you. If your distribution has one of these, use it to see if
      it can find any wireless drivers for you.</p>
    </item>
    <item>
      <p>Use the Windows drivers for your adapter.</p>
      <p>In generale, non è possibile usare un driver dispositivo progettato per un sistema operativo (come Windows) in un altro sistema operativo (come Linux), perché i due sistemi funzionano diversamente. Tuttavia, per gli adattatori WiFi, è possibile installare un emulatore chiamato <em>NDISwrapper</em> che consente di usare alcuni driver WiFi Windows in ambiente Linux. Ciò è utile in quanto sono quasi sempre disponibili driver Windows per adattatori WiFi, mentre i driver Linux non sempre lo sono. È possibile trovare maggiori informazioni sull'utilizzo di NDISwrapper <link href="http://sourceforge.net/apps/mediawiki/ndiswrapper/index.php?title=Main_Page">qui</link>. Notare che NDISwrapper non funziona con tutti i driver WiFi.</p>
    </item>
  </list>

  <p>If none of these options work, you may want to try a different wireless
  adapter to see if you can get that working. USB wireless adapters are often
  quite cheap, and will plug into any computer. You should check that the
  adapter is compatible with your Linux distribution before buying it,
  though.</p>
