Ralink RT2501USB/RT2571W (RT73) devices
This page describes how to enable support for WiFi devices based on the Ralink RT2501USB chipset on Debian systems.
Contents
Drivers
The Ralink RT2501USB wireless LAN chipset is supported by three native drivers:
rt73 (Legacy driver)
- Released by Ralink under the GPL.
- Not generally recommended for use.
- rt73 (Enhanced legacy driver)
- Previously maintained by the rt2x00 project.
Source previously packaged in rt73-source, removed from Debian to resolve bug 563432.
rt73usb (Next-generation driver)
- The recommended driver to use.
Source previously packaged in rt2x00-source, removed from Debian to resolve bug 474189.
- Introduced in Linux 2.6.24.
The next-generation driver is maintained by the rt2x00 project. Supported devices are listed at the end of this page.
This page only details installation of the next-generation driver (rt73usb). It requires non-free firmware for device operation, which can be provided by installing the firmware-ralink package.
The RT2501USB is not to be confused with the RT2500USB, which is supported by different drivers.
Ralink 802.11n USB devices are supported by the rt2870sta driver.
Installation
As drivers from the rt2x00 project are included in the mainline Linux kernel, the rt73usb driver is present on your system.
Firmware is required to be installed prior to device operation:
Add a "non-free" component to /etc/apt/sources.list for your Debian version. For example:
# Debian Squeeze/6.0 deb http://ftp.us.debian.org/debian squeeze main contrib non-free
or
# Debian Lenny/5.0 deb http://ftp.us.debian.org/debian lenny main contrib non-free
Update the list of available packages, then install the firmware-ralink and wireless-tools packages:
aptitude update aptitude install firmware-ralink wireless-tools
- If not already performed, connect the device to your system.
The necessary kernel module should be automatically loaded. If necessary, it can be manually loaded via:
modprobe rt73usb
Verify your device has an available interface:
iwconfig
Raise the interface to activate the radio, for example:
ifconfig wlan0 up
Configure your wireless interface as appropriate.
Troubleshooting
Examine the kernel ring buffer (dmesg(1)) to verify the required firmware files are being loaded by the driver. Lack of firmware is the usual reason for the "SIOCSIFFLAGS: No such file or directory" error message.
Ensure the firmware-ralink package is installed.
Supported Devices
The page HowToIdentifyADevice/USB explains how to identify a USB device.
The following list is based on the alias fields of modinfo rt73usb in Debian 2.6.32 (2.6.32-35) kernel images.
