This article aims to explain the various steps required in configuring Wireless connectivity within Backtrack 4 r2. It is also worth mentioning that as Backtrack is based upon Ubuntu/Debian you may find steps and solutions within this article useful when faced with other Ubuntu/Debian based wireless issues.
1. Install wicd
First you will need to install wicd and remove the standard network-manager (if installed). wicd is an open source wired and wireless network manager for Linux which we will use later to configure your wireless connection.
sudo apt-get update
2. Determine Wireless Card
Next you will need to determine the make and model of your wireless card within your system. This is achieved by running the following command :
root@bt:~# lspci | grep Network
3. Download Drivers
I found the best source for Linux wireless drivers could be found here : http://linuxwireless.org/en/users/Download/stable/
Based on my wireless card being a Atheros AR9285 the ath9k drivers were selected.
4. Confirm MODULE LOAD
Once your system has rebooted confirm that the driver has been loaded by running the following command.
root@bt:~# lshw -C network -network
You can also check to see if the module (driver) is loaded by running the command - lsmod | grep ath9k
5. Configure WiFi Connection
Next you will need to configure your connection, adding your settings such as keys, encryption etc etc. To access the Wicd Network Manager go to "K Menu" --> Select "Internet" and click on "Wicd Network Manager".
Once you have configured your settings you should have the required wireless connectivity within Backtrack.
The main issue I faced when configuring the above was that after adding my wireless key and then trying to connect I would get the message
Unable To Get IP Address
If I then configured a static IP address I received the message,
Connection failed: Could not contact the wireless access point
To resolve this I removed the following file and rebooted.
sudo rm /etc/udev/rules.d/70-persistent-net.rules
