Ralink RT73 USB Wireless Drivers in Feisty Fawn (7.04)

This guide uses p_larbigs's drivers instead of the serialmonkey drivers because p_larbigs's are based off of the serialmonkey drivers, but have been already patched for Fragmentation Attacks and Injection, so you can utilize more features in Aircrack.

The wireless card I tested this on is an Alfa AWUS036S, the system I tested this on is a clean install of Ubuntu Feisty Fawn 7.04 with all updates as of 7/4/07.

Remove the old drivers

Code:

---

cd /lib/modules/2.6.20-16-generic/kernel/ubuntu/wireless/
sudo rm -r rt2x00
sudo rm -r rt2x00-legacy/

---

Get the new drivers and install them
Download http://homepages.tu-darmstadt.de/~p_larbig/wlan/rt73-k2wrlz-1.1.0.tar.bz2 and extract it to your desktop.

Code:

---

cd Desktop/rt73-k2wrlz-1.1.0/Module/
sudo make
sudo strip -S rt73.ko
    (before 2.7MB after 242k)
sudo make install

---

Bring the device up

Code:

---

sudo ifconfig rausb0 up

---

The RT73 drivers do not support the network manager, so you need to remove it and install RutilT, which I like better anyways.

Download and install RutilT
Download http://cbbk.free.fr/bonrom/?download=RutilTv0.15.tar.gz and extract it to your desktop.

Code:

---

sudo apt-get install libgtk2.0-dev g++
cd Desktop/RutilTv0.15/
./configure.sh --launcher=external
sudo make
sudo make install

---

Remove network-manager

Code:

---

sudo apt-get remove network-manager

---

If you want rausb0 brought up when you start ubuntu

Code:

---

sudo gedit /etc/network/interfaces
    auto rausb0
    iface rausb0 inet dhcp

---

If you want RutilT to start with Ubuntu

System>Preferences>Sessions>New>

Name:rutilt, Command:rutilt

If you don't want to see RutilT window every time Ubuntu starts up, inside RutilT check the box next to "Start hidden in tray".

*Just a note, you click on tray icon to show/hide the RutilT window.

Getting Kismet Configured

Code:

---

sudo gedit /etc/kismet/kismet.conf
    #suiduser=(your user name)
    source=rt2500,rausb0,RT73

---

This almost worked for me. The driver is detected and the wireless works... for a short while. I started downloading my Ubuntu updates (from a new install) and the wireless suddenly stopped working altogether. Even during normal browsing, the wireless abruptly ceases to function. Do you know what might cause this to happen? ifconfig shows that all packets are being dropped after a certain point and using any program to attempt to reconnect to the wireless network fails.

Are you using Network-Manager or RutilT?

I fixed it. It had something to do with the ehci_hcd module; I simply removed it.

I was using RutilT and Edgy. RutilT is pretty cool; I like it better than any other WiFi program I've seen. Thanks for the help!

No problem, glad I could help.

thanks for the tutorial!

I had the serial monkey drivers install previously followed the instructions to remove them and install the new ones and they work great, except when doing an arp inject i get:

Read 5842 packets (got 0 ARP requests), sent 0 packets...(0 pps)

so it seems injection still isnt working :(

any suggestions?

Are you fakeauth with the network? and are you sure that a arp request has been captured?(pretty sure its needed before you start injecting)

I went through the instructions without getting any error messages but when I run aireplay-ng to do an injection test on my wireless I get "No Answer..." in response.

What is the problem?

Thanks in advance...

I'll get an "rausb0: ERROR while getting interface flags: No such device" when trying to bring rausb0 up :( What to do ? One another thing, what is that Kismet thing? Can't configure it anyways...

Are you sure your interface is called rausb0 ? What does sudo iwconfig tell you ?
