To set up the encryption simply
enter the the 26 digit key you have set up on your wireless base
station in the "Key" field. Remember from Chapter 3 that encyption keys
are entered in hexadecimal so the key should be prefixed with 0x (which
denote hexadecimal).
Click on OK and return to the main screen. Save the changes and quit
from the configuration tool. The tool will ask you if you wish to
restart the network to make the new changes take effect. Tell the tool
to restart the network after which you should be able to connect to
your encrypted wireless network from your Linux system.
