OTUS(4)		       FreeBSD Kernel Interfaces Manual		       OTUS(4)

NAME
     otus -- Atheros AR9170 USB	IEEE 802.11a/b/g/n 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 otus
	   device wlan

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_otus_load="YES"

DESCRIPTION
     The otus driver supports USB 2.0 wireless network devices based on	the
     Atheros AR9170 chipset.

     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.

     The AR9101	radio supports 1T1R operation in 2GHz only.

     The AR9102	radio supports 2T2R operation in 2GHz only.

     The AR9104	radio supports 2T2R operation both 2GHz	and 5GHz.

     These are the modes the otus driver can operate in:

     BSS mode	    Also known as infrastructure mode, this is used when asso-
		    ciating with an access point, through which	all traffic
		    passes.  This mode is the default.

     The otus 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 communica-
     tion, due to serious weaknesses in	it.

     The otus driver can be configured at runtime with ifconfig(8).

FILES
     The driver	needs at least version 1.0 of the following firmware files,
     which is loaded when an interface is attached:

	   /boot/kernel/otusfw-init.ko
	   /boot/kernel/otusfw-main.ko

HARDWARE
     The otus driver provices support for Atheros AR9170 USB IEEE 802.11b/g/n
     wireless network adapters,	including:

	   3Com	3CRUSBN275
	   Arcadyan WN7512
	   CACE	AirPcap	Nx
	   D-Link DWA-130 rev D1
	   D-Link DWA-160 rev A1
	   D-Link DWA-160 rev A2
	   IO-Data WN-GDN/US2
	   NEC Aterm WL300NU-G
	   Netgear WNDA3100
	   Netgear WN111 v2
	   Planex GW-US300
	   SMC Networks	SMCWUSB-N2
	   TP-Link TL-WN821N v1, v2
	   Ubiquiti SR71 USB
	   Unex	DNUA-81
	   Z-Com UB81
	   Z-Com UB82
	   ZyXEL NWD-271N

EXAMPLES
     Join an existing BSS network (i.e., connect to an access point):

	   ifconfig wlan create	wlandev	otus0 inet 192.168.0.20	\
	       netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig wlan create	wlandev	otus0 ssid my_net up

     Join a specific BSS network with 64-bit WEP encryption:

	   ifconfig wlan create	wlandev	otus0 ssid my_net \
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

DIAGNOSTICS
     %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.

HISTORY
     The otus driver first appeared in OpenBSD 4.6.

AUTHORS
     The otus driver was written by Damien Bergamini <damien@openbsd.org> and
     ported by Adrian Chadd <adrian@freebsd.org>.

CAVEATS
     The otus driver only supports 802.11a/b/g operations.  802.11 operation
     is	not supported at this time.
