UATH(4) 		     Kernel Interfaces Manual			 UATH(4)

NAME
     uath -- Atheros USB IEEE 802.11a/b/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 uath
	   device wlan

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

	   if_uath_load="YES"

DESCRIPTION
     The  uath driver supports USB 2.0 wireless network devices based on Atheros
     Communications fifth generation AR5005UG and AR5005UX chipsets.

     The AR5005UG chipset  is  made  of  an  AR5523  multiprotocol  MAC/baseband
     processor	and  an AR2112 Radio-on-a-Chip that can operate between 2300 and
     2500 MHz (802.11b/g).

     The AR5005UX chipset  is  made  of  an  AR5523  multiprotocol  MAC/baseband
     processor	and an AR5112 dual band Radio-on-a-Chip that can operate between
     2300 and 2500 MHz (802.11b/g) or 4900 and 5850 MHz (802.11a).

     The AR5005UG and AR5005UX chipsets both  have  an	integrated  32-bit  MIPS
     R4000-class processor that runs a firmware and manages, among other things,
     the  automatic  control of the transmit rate and the calibration of the ra-
     dio.

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

FIRMWARE
     uath  requires firmware that is downloaded to the device.	This is normally
     done by the uathload(8) utility that is launched by devd(8) when the device
     is inserted.  uathload includes the firmware in the binary  program.   This
     firmware is licensed for general use and is included in the base system.

HARDWARE
     The uath driver should work with the following adapters:

EXAMPLES
     Join an existing BSS network (i.e., connect to an access point):

	   ifconfig wlan create wlandev uath0 inet 192.168.0.20 \
	       netmask 0xffffff00

     Join a specific BSS network with network name "my_net":

	   ifconfig wlan create wlandev uath0 ssid my_net up

     Join a specific BSS network with 64-bit WEP encryption:

	   ifconfig wlan create wlandev uath0 ssid my_net \
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

     Join a specific BSS network with 128-bit WEP encryption:

	   ifconfig wlan create wlandev uath0 wlanmode adhoc ssid my_net \
	       wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

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

     uath%d:  timeout  waiting for command reply  A read command was sent to the
     firmware but the firmware failed to reply in time.

     uath%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.

HISTORY
     The uath driver first appeared in OpenBSD 4.0.

AUTHORS
     The  uath driver was written by Weongyo Jeong <weongyo@freebsd.org> and Sam
     Leffler <sam@freebsd.org>.  It is distantly related to a driver written  by
     Damien Bergamini <damien@openbsd.org>.

CAVEATS
     Atheros proprietary 108 Mbps mode (aka Super AG mode) is not supported.

     Dual-band	adapters  are  presently not working; to workaround, restriction
     operation to 2.4GHz channels.

FreeBSD 8.3			  April 7, 2009 			 UATH(4)
