      A complete network connection manager
      Wicd supports wired and wireless networks, and capable of
      creating and tracking profiles for both.  It has a
      template-based wireless encryption system, which allows the user
      to easily add encryption methods used.  It ships with some common
      encryption types, such as WPA and WEP. Wicd will automatically
      connect at startup to any preferred network within range.
