I followed adafruit's Acess Point tutorial and I got this error:

Configuration file: /etc/hostapd/hostapd.conf
Line 2: invalid/unknown driver 'rt2870xdrv'
1 errors found in configuration file '/etc/hostapd/hostapd.conf'

ioctl[SIOCSIWMODE]: Invalid argument
Could not set interface to mode(3)!
Could not set interface to master mode!
rtl871xdrv driver initialization failed.

I am using a medialink ralink rt2870/3070. What drivers do I need and what do I need to do?
