Alfa AWUS036AC Linux installation guide from our friends at HackThis
Chris Haralson at HackThis put together a great Linux installation guide for Alfa's new AWUS036AC long range 802.11ac Wi-Fi USB adapter.
If you are running Linux and are looking to upgrade your Wi-Fi to the latest 802.11ac standard with speeds up to 867 Mbps, the AWUS036AC is a great option and the guide will show you how to install it.
Also, be sure to check out the HackThis web site for a wide variety of Linux related projects, tutorials, and product reviews.
Alfa AWUS036NHR is Backtrack 5/Linux compatible
Alfa’s AWUS036NHR is Linux
compatible. It also works with Backtrack 5 (BT5), but is not plug and play. Driver
installation is needed (note: at this time it does not appear to be possible to
get AWUS036NHR into monitor mode AND have 802.11n capabilities at the same
time, see Alfa’s AWUS036NH or Rokland’s n3 for 802.11n and monitor
mode capability in Backtrack 5).
The following is a quick-install
guide for Linux users. This should allow you to use your AWUS036NHR for Wi-Fi
access in most recent Linux distributions running kernel 2.6.38, but as noted,
monitor mode does not appear to be supported by this driver. Further down we
have a link to a driver that is reported to allow you to use AWUS036NHR in
monitor mode, but the corresponding web page notes the device will only have
802.11g functionality.
To install your Realtek RTL8188RU based AWUS036NHR in Linux, first download the driver here. The following steps were taken on an HP laptop running Backtrack 5, but the steps should be similar for other recent Linux distros.
*If you are not able to unzip the driver download file in Linux, you will need to download the file to a Windows computer to unzip and then copy the contents to your Linux computer via flash drive or another method.
1. When you have the files
extracted on your Linux machine, open a terminal window and navigate to the
location of the drivers.
2. Type ./install.sh to install
the driver package
3. If installation completes
successfully, then you can connect the Alfa adapter to the computer and open
“Wicd Network Manager” from the Internet menu to connect to networks. Inside
Wicd, click Preferences and change the network device to the AWUS036NHR
adapter. If you are not sure of the device name, in a terminal window type
“iwconfig” without quotes and it will list it there. Commonly the device will
be called wlan0, wlan1, or wlan2 depending on whether you have other wireless
cards installed on the computer.
4. If you receive a makefile
error about “no rule to make target modules”, you may need to prepare kernel
headers. As root, at the command line run these commands (you will need to have
Internet access on the computer already):
prepare-kernel-sources
cd /usr/src/linux
cp -rf include/generated/* include/linux/
5. Upon completion, repeat step number 2 above to complete driver installation. Then connect the adapter to the computer and proceed to step 3.
URTWN Driver:
There is a driver called urtwn which specifies compatibility with RTL8188RU chipset-based devices, and allows for them to be put into monitor mode. The documentation for the driver explains that 802.11n functionality is not supported, so RTL8188RU devices will only operate in B/G mode. Rokland has not yet tried to use this driver with AWUS036NHR and is not able to offer installation assistance or support. You can visit this site for download information and more details:
