#REDIRECT [[Wireless Setup#rt2x00]]
This page describes how you can make the original Ralink '''RT73''' (aka '''RT2571''') drivers work. This page does not describe how to make the new from-scratch drivers written by the rt2x00 project. (For rt2x00, visit [[Using_the_new_rt2x00_beta_driver|rt2x00 wiki page]])
Several USB WiFi dongles use this chipset, including the Linksys WUSB54GC
= Installing the driver =
== Preparation ==
Download the Ralink RT73 source from here: http://www.ralinktech.com/drivers/Linux/RT73_Linux_STA_Drv1.0.3.6.tar.gz.
Unpack the driver and change directory:
tar xvf RT73_Linux_STA_Drv1.0.3.6.tar.gz
cd RT73_Linux_STA_Drv1.0.3.6
cd Module
We need to use the "Makefile.6" file that shipped with the tarball:
cp Makefile.6 Makefile
The Ralink RT73 driver ships with several Device IDs already configured. First of all, check your Device ID using '''lsusb'''.
Edit the driver file containing Device IDs:
nano rtmp_def.h
At the very bottom of the file is a section titled '''VID/PID'''
Make sure your Device ID is listed, if it is not, add it in the same format as those listed somewhere before the end marker.
For example, the Linksys WUSB54GC has Device ID 0x13b1,0x0020.
The line in rtmp_def.h would look like this:
{USB_DEVICE(0x13b1,0x0020)}, /* Linksys WUSB54GC */      \
''Note:'' Replace 0x13b1 and 0x0020 with the Device ID for '''your''' WiFi dongle.
''Note:'' Make sure the line you add ends with a backslash '''\'''
== Building The Driver ==
After the build is finished, copy new module to kernel tree
cp rt73.ko /lib/modules/2.6.18-ARCH/kernel/drivers/net/wireless/
Install module:
insmod /lib/modules/2.6.18-ARCH/kernel/drivers/net/wireless/rt73.ko
Update modules.dep:
depmod -a
== Install Firmware ==
Now copy the RT73 firmware that shipped in the driver tarball to the appropriate location:
cp rt73.bin /lib/firmware
Copy the rt73sta.dat file from the Module directory to this location:
cp rt73sta.dat /etc/Wireless/RT73STA
The rt73sta.dat file needs to be modified with your wireless network settings. This process will be described below.
= Testing The Driver =
We will now test the functionality of the driver we just installed before altering the rc.conf file. This method may also be used when the WiFi dongle is used infrequently or you prefer retaining control over the entire connection process.
''Note:'' These steps may also be thrown in a script if you prefer.
Plug your WiFi dongle into a USB port.
Make sure the device is recognized using:
You can check to make sure your system realizes its a wireless device using:
There should be a device named '''rausb0''' near the bottom.
Bring the WiFi dongle up using:
ifconfig rausb0 up
The '''rausb0''' device should show up now in:
Although without an IP address since we aren't associated with an Access Point(AP) yet.
You can associate the WiFi dongle with an AP using:
iwconfig rausb0 essid <your_ESSID>
Or, if you have WEP:
iwconfig rausb0 essid <your_ESSID> key <your_WEP_key>
Remember you can scan for APs using:
iwlist rausb0 scan
Finally, let the dhcpcd client get an IP address for your WiFi dongle.
dhcpcd rausb0
If everything worked you should now have network access using your WiFi dongle. If you don't, check the routes:
There should be a path to your gateway listed. If there is not, you can set one up using:
route add default gw <gateway-ip> rausb0
= Non-Roaming Setup =
This section is being provided as an alternative to the '''Setup and Boot''' section of the [[Wireless]] page specifically for this hardware (RT73). This method has not been tested with other devices.
Edit the rt73sta.dat file:
nano /etc/Wireless/RT73STA/rt73sta.dat
Replace placeholders in the file with your wireless network settings.
Edit /etc/rc.conf to initiate dhcp on rausb0 at bootup:
# /etc/rc.conf
INTERFACES=(lo rausb0)
