ZyDAS ZD1201 devices

This page describes how to enable support for WiFi devices based on the ZyDAS ZD1201 chipset on Debian systems.

?TableOfContents(2)

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

Firmware is required, you must [#firmware acquire and install the firmware] prior to device operation.

Installation

Driver

The zd1201 driver is included in the mainline Linux kernel since 2.6.12. It is present in Debian kernel images.

?Anchor(firmware)

Firmware

  1. Acquire the firmware tarball:

    $ wget 'http://prdownloads.sourceforge.net/linux-lc100020/zd1201-0.14-fw.tar.gz?download'
  2. Extract the firmware files to /lib/firmware:

    $ tar xvf zd1201-0.14-fw.tar.gz
    $ su
    # cp -v zd1201-0.14-fw/*.fw /lib/firmware

Configuration

  1. Install the wireless-tools package:

    # aptitude update
    # aptitude install wireless-tools
  2. Physically connect the device to your system.
  3. The necessary kernel module should be [:Modules:automatically loaded]. If necessary, it can be manually loaded via:

    # modprobe zd1201
  4. Verify your device has an available interface:

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

    # ifconfig eth1 up
  6. [:WiFi/HowToUse:Configure] your wireless interface as appropriate.

Troubleshooting

  • Examine the kernel ring buffer (dmesg) to verify required firmware files are being loaded by the driver. If requested firmware is not available, no wireless interface will be created.

Known Issues

  • This driver does not support ["WPA"]?FootNote(http://bugzilla.kernel.org/show_bug.cgi?id=5631).
