ZyDAS ZD1211/ZD1211B and Atheros AR5007UG devices

This page describes how to enable support for WiFi devices based on ZyDAS ZD1211 chipsets on Debian systems.

zd1211rw is a module for ZyDAS ZD1211, ZD1211B and Atheros AR5007UG USB 802.11g wireless LAN chipsets. This is not to be confused with the zd1201 module which supports the ZD1201 802.11b chipset.

After being acquired by Atheros, the ZyDAS ZD1211B chipset was rebranded as the "Atheros AR5007UG" (also known as AR2524/AR5524). Devices with chipsets bearing these names are also supported.

Non-free firmware is required, which can be provided by installing the zd1211-firmware package.

Installation

The zd1211rw driver is included in the mainline Linux kernel since 2.6.18. It is present in Debian kernel images.

  1. Add a "non-free" component to /etc/apt/sources.list for your Debian version, for example:

    # Debian Lenny/5.0
    deb http://ftp.us.debian.org/debian lenny main contrib non-free
  2. Install the wireless-tools and zd1211-firmware packages:

    aptitude update
    aptitude install wireless-tools zd1211-firmware
  3. Physically connect the device to your system.
  4. The necessary kernel module should be automatically loaded. If necessary, it can be manually loaded via:

    modprobe zd1211rw
  5. Verify your device has an available interface:

    iwconfig
  6. Raise the interface to activate the radio, for example:

    ifconfig wlan0 up
  7. Configure your wireless interface as appropriate.

Troubleshooting
