The secured network problem points to a problem with wpa_supplicant. Try doing it by hand
iwlist wlan0 scan Less
Find your network and address (a mac address, e.g. 00:11:22:33:44:55) run your mouse over the mac address. Then
iwconfig wlan0 essid your_essid ap <paste mac address>
when you run iwconfig you should see the word 'associated'
Then kill any running dhcp processes and run dhcpcd or dhclient
Sounds like bad info in /etc/sysconfig
