|
.Nd Atheros AR9170 USB IEEE 802.11a/b/g/n 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 otus"
|
|
.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_otus_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver supports USB 2.0 wireless network devices based on the Atheros
|
|
AR9170 chipset.
|
|
.Pp
|
|
The Atheros AR9170 is a draft-802.11n adapter that uses an external
|
|
radio to operate in either 2.4GHz only or 2.4GHz and 5GHz.
|
|
.Pp
|
|
The AR9101 radio supports 1T1R operation in 2GHz only.
|
|
.Pp
|
|
The AR9102 radio supports 2T2R operation in 2GHz only.
|
|
.Pp
|
|
The AR9104 radio supports 2T2R operation both 2GHz and 5GHz.
|
|
.Pp
|
|
These are the modes the
|
|
.Nm
|
|
driver can operate in:
|
|
.Bl -tag -width "IBSS-masterXX"
|
|
.It BSS mode
|
|
Also known as
|
|
.Em infrastructure
|
|
mode, this is used when associating with an access point, through
|
|
which all traffic passes.
|
|
This mode is the default.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver can be configured to use
|
|
Wired Equivalent Privacy (WEP) or
|
|
Wi-Fi Protected Access (WPA-PSK and WPA2-PSK).
|
|
WPA is the de facto encryption standard for wireless networks.
|
|
It is strongly recommended that WEP
|
|
not be used as the sole mechanism
|
|
to secure wireless communication,
|
|
due to serious weaknesses in it.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver can be configured at runtime with
|
|
.Xr ifconfig 8 .
|
|
.Sh FILES
|
|
The driver needs at least version 1.0 of the following firmware files,
|
|
which is loaded when an interface is attached:

|
|
The

|
driver provices support for Atheros AR9170 USB IEEE 802.11b/g/n
|

.Sh EXAMPLES
|
|
Join an existing BSS network (i.e., connect to an access point):
|
|
.Bd -literal -offset indent
|
|
ifconfig wlan create wlandev otus0 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 otus0 ssid my_net up"
|
|
.Pp
|
|
Join a specific BSS network with 64-bit WEP encryption:
|
|
.Bd -literal -offset indent
|
|
ifconfig wlan create wlandev otus0 ssid my_net \e
|
|
wepmode on wepkey 0x1234567890 weptxkey 1 up
|
|
.Ed
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "%s: failed load firmware of file otusfw-main"
|
|
For some reason, the driver was unable to read the microcode file from the
|
|
filesystem.
|
|
The file might be missing or corrupted.
