WPA security and AP mode not working but manufacturer's site says it does

Hi ,
I have a Ubuntu 12.04 on laptop with Intel PRO/Wireless 3945ABG wireless card (details from lshw).

Intel website states that WPA is supported as well as Infrastructure mode.here

While here on linux drivers page it only supports ad-hoc.
From : iw list Supported interface modes:
* IBSS
* managed
* monitor
I believed wieless cards after 2003 supported WPA and WPA2
Is this a driver problem on linux?Does my card support WPA and AP or not?

Yes, it does. "managed" is the regular infrastructure mode

I would like to create a wifi hotspot for which I need Master(AP) mode.Managed mode makes it work as a client.I don't think my card supports it but I wanted to make sure if it's not a driver problem.Even WPA is not supported.
