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
The Ralink RT2501USB wireless LAN chipset is supported by the rt73usb Linux kernel driver, introduced at Linux 2.6.24. Supported devices are listed at the end of this page.
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 the rt2500usb driver.
Ralink 802.11n USB devices are supported by the rt2800usb driver.
Installation
Firmware is required for device operation:
Add a "non-free" component to /etc/apt/sources.list for your Debian version. For example:
# Debian 8 "Jessie" deb http://http.debian.net/debian/ jessie main contrib non-free
Update the list of available packages and install the firmware-ralink package:
# apt-get update && apt-get install firmware-ralink
Connect the device to your system. The rt73usb kernel module is automatically loaded for supported devices.
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
