.Sh NAME
.Nm zyd
.Nd ZyDAS ZD1211/ZD1211B USB IEEE 802.11b/g wireless network device
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device ehci"
.Cd "device uhci"
.Cd "device ohci"
.Cd "device usb"
.Cd "device zyd"
.Cd "device wlan"
.Cd "device wlan_amrr"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_zyd_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver provides support for wireless network adapters based around
the ZyDAS ZD1211 and ZD1211B USB chips.
.Pp
.Nm
supports
.Cm station ,
.Cm adhoc ,
and
.Cm monitor
mode operation.
Only one virtual interface may be configured at any time.
For more information on configuring this device, see
.Xr ifconfig 8 .

.Sh EXAMPLES
The following
examples configures zyd0 to join any BSS network using WEP key
.Dq 0x1deadbeef1 ,
channel 11:
.Bd -literal -offset indent
ifconfig wlan create wlandev zyd0 channel 11 \e
    wepmode on wepkey 0x1deadbeef1 weptxkey 1 \e
    inet 192.168.1.1 netmask 255.255.255.0
.Ed
.Pp
Join an existing BSS network,
.Dq my_net :
.Bd -literal -offset indent
ifconfig wlan create wlandev zyd0 192.168.0.2 \e
    netmask 0xffffff00 ssid my_net

.Sh DIAGNOSTICS
.Bl -diag
.It "zyd%d: could not load firmware (error=%d)"
An error occurred while attempting to upload the firmware to the onboard
microcontroller unit.
.It "zyd%d: could not send command (error=%s)"
An attempt to send a command to the firmware failed.
.It "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.
.It "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.
.It "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.

.Sh AUTHORS
.An -nosplit
The original
.Nm
driver was written by
.An Florian Stoehr Aq ich@florian-stoehr.de ,
.An Damien Bergamini Aq damien@openbsd.org ,
and
.An Jonathan Gray Aq jsg@openbsd.org .
.Sh CAVEATS
The
.Nm
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.
