Hi all,

I need some help sorry if this bit newbie question. I have a ALFA AWUS036NH with RT3070 chip-set and trying to use it with air-crack. My question is do I need to download drivers for it to work? or does BT4 already have them installed ?

When I run
airmon-ng start wlan0
I get

wlan0           Ralink RT2870/3070      rt2800usb - [phy0]
                                (monitor mode enabled on mon3)
mon0            Ralink RT2870/3070      rt2800usb - [phy0]
mon1            Ralink RT2870/3070      rt2800usb - [phy0]
mon2            Ralink RT2870/3070      rt2800usb - [phy0]
when i try [
CODE]aireplay-ng -9 wlan0[/CODE]

I get
ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211,
ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead.  Make
sure RFMON is enabled: run 'airmon-ng start wlan0 <#>'
Sysfs injection support was not found either.

any help or points in the right direction will be nice thanks
