In some cases, your wireless network device may need a restricted driver in
100
order to operate. The easiest and best way to check this is to open the
101
application named <application>Jockey</application>. To open

<application>Jockey</application>, go to &menujockey;. If you have a device that
103
requires a restricted driver, <application>Jockey</application> will inform you

and assist you in selecting the driver, installing it, and activating it. If
105
this step is necessary or completed, then you are ready to configure wireless

connections. You will have to reboot your machine if you installed a restricted
107
driver before the device will work.
