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
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 radio.
uath 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).
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(8) 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.
