WPA Password not remembered after a reboot

Every-time I reboot my laptop with WinXP, I have to re-enter my wireless password. I've looked but found no place to check to tell it to remember it. This worked at one time but I'm not sure what changed. Any Ideas?

Thanks.

From here:

To enable automatic configuration, ensure the "Use Windows to configure my wireless network settings" checkbox is checked on the Wireless Networks tab of the Wireless Network Connection properties window. Automatic wireless Internet / Wi-Fi network configuration will be disabled if this checkbox is unchecked. You must be logged on with Windows XP administrative privileges to enable / disable this feature.
