unicorn Firstly you can try to type
ifconfig and see if your wireless device show up?
Next step probably create a
/etc/hostname.yourdevice I don't know what is device name you have but for me is
urtwn0 so I will create a file
And it will look like this
nwid "Your Network" wpakey "insecurepassword123"
Last thing to do. Try to run this command as root
sh /etc/netstart and it should work like charm.
