How to get ar9170 chipset usb adapter working

[dustyboner]

****AR9170 DEVICES SHOULD WORK OUT-OF-THE-BOX ON THE BackTrack 4 R2 Release****

If yours doesn't;
I noticed that the BackTrack 4 R2 iso doesn't have the one stage firmware, which is needed for the AVM FRITZ!WLAN USB Stick N and AVM FRITZ!WLAN USB Stick 2.4 and possibly others. So any one still having problems, see if you have ar9170.fw in /lib/firmware.
If you are missing it:
Download ar9170.fw and put it in /lib/firmware.

This applies to the original Backtrack4 release only.


The following devices with the atheros AR9170 chipset need the drivers updated to work correctly with BT4:

• Arcadyan - WN7512
• Atheros - 9170
• Atheros - TG121N
• AVM - FRITZ!WLAN USB Stick N
• AMV - FRITZ!WLAN USB Stick N 2.4
• Cace - Airpcap NX
• D-Link - DWA 160A1
• D-Link - DWA 160A2
• IO-Data - WNGDNUS2
• Netgear - WNDA3100
• Netgear - WN111 v2
• Planex - GWUS300
• Sphairon - Homelink 1202
• TP-Link - TL-WN821N v2
• Z-Com - UB81 BG
• Z-Com - UB82 ABG
• Zydas - ZD1221
• Zyxel - NWD271N

Here is how to update the drivers:

Download ar9170.fw, ar9170-1.fw, ar9170-2.fw and put them into /lib/firmware

Download compat-wireless-2.6.32.3.tar.bz2

Open a terminal and run:

tar -xf /root/compat-wireless-2.6.32.3.tar.bz2
cd compat-wireless-2.6.32.3
make
make install
make unload

*If you get a "No such file or directory" error when you run make, run this command:

ln -s /usr/src/linux /lib/modules/2.6.30.9/build

Open /etc/modprobe.d/blacklist with any text editor and add blacklist arusb_lnx to the list and save the file.

then:

reboot
