Using the driver
--------------------

This procedure is required after every reboot of your phone, if you want to
use this driver!

* Open X Terminal

* Gain root access

~$ sudo gainroot

* Load the driver

# cd MyDocs/wl1251-maemo/binary/compat-wireless
# sh load.sh

* Unloading the driver (just in case you run into problems and want to
switch back to the stock wl12xx driver)

# sh unload.sh

If you get an error file is not installed
