Wireless radio doesn't automatically start when rebooting

Hello

I've been having problems getting my Atheros AR5005G Wireless Network Adapter to turn it's radio on automatically at every reboot.
All this happening on a Fujitsu Siemens Amilo L7320GW with PhoenixBIOS Setup Utility.
I just can't find my way around the BIOS to make the radio turn it's self on at every reboot, so I have to manually turn the radio on with Fn+F2 keys at every start-up.
I know that Bluetooth and other devices like these can be enabled or disabled from BIOS... but this PhoenixBIOS doesn't let me do anything.

Also... I have a few problems getting Windows XP SP2 to connect to my D-Link DI-624 Router through WPA2 Password Authentication. It seems to be stuck on WEP Open or Shared key... This being my Home network I don't mind changing the security Authentication method, it's just that I prefer WPA2, since more then 2 machines might connect to the AP.

I'm not sure what other information I have to post, and since I'm not actually sure what the problem is I don't know whether the problem is properly posted under Networking.

Thank you for your understanding.
