  <title>无线网络故障排除</title>

  <subtitle>确保所需的设备驱动已经安装</subtitle>

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

  <p>在这步中可以检查您的无线适配器驱动是否正常工作。<em>设备驱动</em> 是一种帮助电脑同硬件设备协同工作的软件。尽管电脑已经识别出无线适配器，设备驱动仍可能存在问题。您可能找到其他能够工作的驱动，请尝试下列几个：</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="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>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>一些 Linux 发行版带有工具软件，可以为您下载受限驱动。如果您的发行版也有，请使用它来搜索是否有可用的无线设备驱动。</p>
    </item>
    <item>
      <p>Use the Windows drivers for your adapter.</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>如果这些选项都不能解决，您可以要换一个其他无线设备，看看是否能正常工作。USB 无线适配器通常很便宜，可以接到任何计算机上。但是，您在购买前，应当检查它是否跟您的 Linux 发行版相兼容。</p>
