For wpa encryption, you need either Network Manager or wpa_supplicant.
Network Manager is by far the easiest to get going: yum install it, and then start it by running "/etc/init.d/NetworkManager start". You should then have an icon on your panel --if it is not-try the command: nm-applet --sm-disable. Click on it, and look for your Dad's ssid in the list, click on the ssid, and you will be prompted for a password, enter it, and you are good to go. To get it to run everytime you boot, go to System-->services and check the Network Manager box.
wpa_supplicant is not terribly difficult to set up, but it is not as elegant as Network Manager is at this point. Edit /etc/sysconfg/wpa_supplicant to indicate your wireless interface and driver. Then, edit /etc/wpa_supplicant/wpa_supplicant.conf and change the following lines:
ssid="(your dad's ssid)"
Then go to system-->services and check the wpa_supplicant box.
