Hello, It is not very clear in your request, but it might be that you are looking for a specific WPA2 reference in the manual. I wasn't able to find one and I thought WPA2 is not supported. It is supported in fact and you can use wpa tags to use it - the driver will be able to select between wpa or wpa2, TKIP or AES.
If this is not the case and you are absolutely new in setting up wireless, issue a man <your_wireless_device> and you will have a nice collection of examples. Bye.
