uath
— Atheros USB
IEEE 802.11a/b/g wireless network device
uath* at uhub? port ?
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 2500MHz (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 2500MHz (802.11b/g) or 4900 and 5850MHz (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.
These are the modes the uath
driver can
operate in:
uath
supports hardware WEP. It can be
typically configured in one of three modes: no encryption; 40-bit
encryption; or 104-bit encryption. It is strongly recommended that WEP not
be used as the sole mechanism to secure wireless communication, due to
serious weaknesses in it.
The uath
driver can be configured at
runtime with ifconfig(8) or on boot
with hostname.if(5).
The following firmware file is loaded when a device is plugged:
This firmware file is not freely redistributable.
A prepackaged version of the firmware can be installed using fw_update(8).

The following example scans for available networks:
# ifconfig uath0 scan
The following hostname.if(5) example configures uath0 to join network “mynwid”, using WEP key “mywepkey”, obtaining an IP address using DHCP:
join mynwid nwkey mywepkey inet autoconf
arp(4), ifmedia(4), intro(4), netintro(4), usb(4), hostname.if(5), ifconfig(8)
The uath
driver first appeared in
OpenBSD 4.0.
The uath
driver was written by
Damien Bergamini
<damien.bergamini@free.fr>.
Atheros Communications refuses to release any documentation for their products. Atheros proprietary 108 Mbps mode (aka Super AG mode) is not supported.
The uath
driver does not attempt to do any
regulation of radio frequencies.
This driver does not support powersave mode.
