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.

?TableOfContents(2)

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-rc1. It is present in Debian kernel images.

<!> [:DebianEtch:Etch] users: Some ZD1211/ZD1211B devices may not be known to the zd1211rw driver in the 2.6.18 kernel. Refer to the [#troubleshoot troubleshooting section] to install a 2.6.24 kernel image.

  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

    or

    # Debian Etch/4.0
    deb http://ftp.us.debian.org/debian etch 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 [:Modules: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. [:WiFi/HowToUse:Configure] your wireless interface as appropriate.

Troubleshooting

Supported Devices

The page ["HowToIdentifyADevice/USB"] explains how to identify a USB device.

The following list is based on the alias fields of  modinfo zd1201 on Lenny.
