.Sh NAME
.Nm uath
.Nd Atheros USB IEEE 802.11a/b/g wireless network device
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device ehci"
.Cd "device uhci"
.Cd "device ohci"
.Cd "device usb"
.Cd "device uath"
.Cd "device wlan"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
if_uath_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports USB 2.0 wireless network devices based on Atheros
Communications fifth generation AR5005UG and AR5005UX chipsets.
.Pp
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).
.Pp
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).
.Pp
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.
.Pp
.Nm
supports
.Cm station ,
and
.Cm monitor
mode operation.
Only one virtual interface may be configured at any time.
For more information on configuring this device, see
.Xr ifconfig 8 .
.Sh FIRMWARE
.Nm
requires firmware that is downloaded to the device.
This is normally done by the
.Xr uathload 8
utility that is launched by
.Xr devd 8
when the device is inserted.
.Xr uathload
includes the firmware in the binary program.
This firmware is licensed for general use and is included in the base system.
.Sh HARDWARE

.Nm
driver should work with the following adapters:

.Sh EXAMPLES
Join an existing BSS network (i.e., connect to an access point):
.Bd -literal -offset indent
ifconfig wlan create wlandev uath0 inet 192.168.0.20 \e
    netmask 0xffffff00
.Ed
.Pp
Join a specific BSS network with network name
.Dq Li my_net :
.Pp
.Dl "ifconfig wlan create wlandev uath0 ssid my_net up"
.Pp
Join a specific BSS network with 64-bit WEP encryption:
.Bd -literal -offset indent
ifconfig wlan create wlandev uath0 ssid my_net \e
	wepmode on wepkey 0x1234567890 weptxkey 1 up
.Ed
.Pp
Join a specific BSS network with 128-bit WEP encryption:
.Bd -literal -offset indent
ifconfig wlan create wlandev uath0 wlanmode adhoc ssid my_net \e
    wepmode on wepkey 0x01020304050607080910111213 weptxkey 1
.Ed
.Sh DIAGNOSTICS
.Bl -diag
.It "uath%d: could not send command (error=%s)"
An attempt to send a command to the firmware failed.
.It "uath%d: timeout waiting for command reply"
A read command was sent to the firmware but the firmware failed to reply in
time.
.It "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.
