uath — Atheros USB IEEE 802.11a/b/g wireless network device
Contents
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.
Debian April 7, 2009 UATH(4)
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).
Diagnostics
uath%d:couldnotsendcommand(error=%s) An attempt to send a command to the firmware failed.
uath%d:timeoutwaitingforcommandreply A read command was sent to the firmware but the firmware
failed to reply in time.
uath%d:devicetimeout A frame dispatched to the hardware for transmission did not complete in time.
The driver will reset the hardware. This should not happen.
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”:
ifconfigwlancreatewlandevuath0ssidmy_netup
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
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.
