NAME

       zyd — ZyDAS ZD1211/ZD1211B USB IEEE 802.11b/g wireless network device

SYNOPSIS

       To compile this driver into the kernel, place the following lines in your kernel configuration file:

             device ehci
             device uhci
             device ohci
             device usb
             device zyd
             device wlan
             device wlan_amrr

       Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

             if_zyd_load="YES"

DESCRIPTION

       The  zyd  driver provides support for wireless network adapters based around the ZyDAS ZD1211 and ZD1211B
       USB chips.

       zyd supports station and monitor mode operation.  Only one virtual interface may  be  configured  at  any
       time.  For more information on configuring this device, see ifconfig(8).

EXAMPLES

       The following example configures zyd0 to join any BSS network using WEP key “0x1deadbeef1”, channel 11:

             ifconfig wlan create wlandev zyd0 channel 11 \
                 wepmode on wepkey 0x1deadbeef1 weptxkey 1 \
                 inet 192.168.1.1 netmask 255.255.255.0

       Join an existing BSS network, “my_net”:

             ifconfig wlan create wlandev zyd0 192.168.0.2 \
                 netmask 0xffffff00 ssid my_net

DIAGNOSTICS

       zyd%d:  could  not load firmware (error=%d)  An error occurred while attempting to upload the firmware to
       the onboard microcontroller unit.

       zyd%d: could not send command (error=%s)  An attempt to send a command to the firmware failed.

       zyd%d: sorry, radio %s is not supported yet  Support for the specified radio chip is not yet  implemented
       in the driver.  The device will not attach.

       zyd%d: device version mismatch: 0x%x (only >= 43.30 supported)  Early revisions of the ZD1211 chipset are
       not supported by this driver.  The device will not attach.

       zyd%d: device timeout  A frame dispatched to the hardware for transmission did not complete in time.  The
       driver will reset the hardware.  This should not happen.

AUTHORS

       The original  zyd  driver  was  written  by  Florian  Stoehr  <ich@florian-stoehr.de>,  Damien  Bergamini
       <damien@openbsd.org>, and Jonathan Gray <jsg@openbsd.org>.

CAVEATS

       The  zyd  driver  does  not  support  a lot of the functionality available in the hardware.  More work is
       required to properly support the IBSS and power management features.
