<title>Wireless</title>
<para>
In some cases, the wireless network device may need a restricted driver in
order to operate. The best way to check this is to open the application named
<application>Jockey</application>. To open <application>Jockey</application>, go
to &menujockey;. If the wireless network device requires a restricted driver,
<application>Jockey</application> will provide that information and assist with
selecting, installing and activating the proper driver. When this step is
completed, wireless connections can be  configured. The machine must be
rebooted before the newly installed, restricted driver will make the wireless
device work.
</para>
<procedure><title>Connecting to a wireless network</title>

Ensure that the wireless device is turned on. Most modern laptop computers have
a physical switch for wireless.

<para>
Enter any other information required for the connection, especially if
the owner has established wireless security for the network.

<para>
If the machine has been connected to a wireless network previously, &kubuntu;
can automatically connect to the network where it is available. This selection
option should be chosen when the initial connection to the network is being
configured.

<para>
When both wired and wireless network connections are available, the wired
connection will be used by default.
