I'm trying to install a driver for backtrack to see my netgear wgn511 notebook card.
i did some research and everyone is telling me to use ndiswrapper however i want to test my routers defenses and crack into my router but everytime i use airmon-ng it says

Interface Chipset Driver

wlan0 Unknown ndiswrapper

and i go on with airodump-ng and it states

Ndiswrapper doesn't support monitor mode.

is there anyway that i can install the driver without ndiswrapper?
