Hello. I have a D-Link DWA-520 wireless adapter (Atheros Communications Inc. AR5212/AR5213 Multiprotocol MAC/baseband processor (rev 01)), which supports turbo mode with 108Mbps rate. However, i can't get this mode working, maximum rate that I can set is 54Mbps. With ndiswrapper this rate is enabled by default.
Here is iwconfig:
