<desc>Some device drivers don’t work very well with certain wireless
 adapters, so you may need to find a better one.</desc>

In this step you can check to see if you can get working device drivers
 for your wireless adapter. A device driver is a piece of software
 which tells the computer how to make a hardware device work properly. Even
 though the wireless adapter has been recognized by the computer, it may not
 have drivers which work very well. You may be able to find different drivers
 for the wireless adapter which do work. Try some of the options below:

<list>
 <item>
 Check to see if your wireless adapter is on a list of supported
 devices.
 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.
 </item>
 <item>
 Look for restricted (binary) drivers.
 Many Linux distributions only come with device drivers which are
 free and open source. 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.
 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.
 </item>
 <item>
 Use the Windows drivers for your adapter.
 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
 NDISwrapper 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="http://sourceforge.net/apps/mediawiki/ndiswrapper/index.php?title=Main_Page">here</link>.
 Note that not all wireless drivers can be used through NDISwrapper.
 </item>
 </list>

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.
