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):
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 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

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.
