UATH(4)		       FreeBSD 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 pro-
     cessor 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 pro-
     cessor 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 radio.

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

FIRMWARE
     uath requires firmware that is downloaded to the device.  This is nor-
     mally 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 transmis-
     sion 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 writ-
     ten 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.
