ZD1211RW

Right playing around with pwnpi a lovely little security distro for the raspberry pi

had issues with a Zydas 1211 adaptor (belkin).

airmon-ng start wlan0


Found 2 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

PID     Name
885     dhclient3
1527    dhclient3
Process with PID 1527 (dhclient3) is running on interface wlan0


Interface       Chipset         Driver

wlan0           Zydas   zd1211rw - [phy0]SIOCSIFFLAGS: No such file or directory

                                (monitor mode enabled on mon0)

Found a lovely fix

wget http://downloads.sourceforge.net/project/zd1211/zd1211-firmware/1.4/zd1211-firmware-1.4.tar.bz2

tar xvjf zd1211-firmware-1.4.tar.bz2

mv zd1211-firmware zd1211

mv zd1211 /lib/firmware

and now you can do packet injection on the pi.
