Thanks, I will try that SOFTMAC driver.
I thought about that before, because Netgear provides only one driver (a Softmac
driver) for both versions of the WG511 (Made in China and made in Taiwan)
(see here: http://de.gentoo-wiki.com/WG511)

I did some further test with different firmware versions using Windows which I
reported in the prism54.org Forum, but the posting is gone (the Link doesn't
work anymore perhaps it was removed by an admin?)

I will try to summarize it here:
- first of all, I use the Netgear WG511 FULLMAC version (Made in Taiwan)

- The best encryption of the (Fullmac) firmware is WPA2 + TKIP. (1.0.4.3.arm)

- The windows driver on Netgear Homepage for WG511 contains a Softmac Firmware
(2.4.12.0.arm) included in WG511ICB.sys and supports only WPA + TKIP

- I tried to use the driver from MC2835WV2-V3_112WW.zip (2.13.1.0.arm) included
in 2835wc51.sys for my Netgear card successfully with WPA2 + AES using windows
or Linux with Ndiswrapper

- I found another firmware (2.13.8.0.arm) which is not listed on
http://daemonizer.de/prism54/prism54-fw/
If someone knows how to extract the firmware from the windows driver (named
wlanCIG.sys) you can get it here:
http://www.funkwerk-ec.com/portal/downloadcenter/dateien/FEC_W-Clients/FEC_W-Client_CB_PCI_mPCI_11g_v3320_1.zip
It works although fine with Netgear WG511 and WPA2 + AES encryption.

Conclusion:
It seems that Softmac firmware version greater than 2.13.x.x have WPA2 + AES
Support, perhaps this helps for further development or reverse engineering of
the firmware.
(I could although provide debug traces from wpa_supplicant when using WPA2 + AES
with ndiswrapper if that helps)
