otus
driver supports USB 2.0 wireless network
devices based on Atheros Communications AR9001U chipset.
The AR9001U chipset is made of an AR9170 MAC/Baseband and an AR9101 (1T2R), AR9102 (2T2R) or AR9104 (dual-band 2T2R) Radio.
These are the modes the otus
driver can
operate in:
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 communication, due to serious weaknesses in it.
The otus
driver can be configured at
runtime with ifconfig(8) or
on boot with
ifconfig.if(5).
Although these firmware files are freely redistributable, their usage is restricted.

Join an existing BSS network, “my_net”:
# ifconfig otus0 192.168.1.1 netmask 0xffffff00 nwid my_net
To use WPA, see wpa_supplicant(8) and wpa_supplicant.conf(5).
otus
driver first appeared in
OpenBSD 4.6. It was ported to
NetBSD by Anon Ymous and first appeared in
NetBSD 6.0.
otus
driver was written by Damien
Bergamini
<damien@openbsd.org>
based on source code licensed under the ISC released in 2008 by Atheros
Communications for Linux.
The otus
driver does not support any of
the 802.11n capabilities offered by the AR9001U chipset. Additional work is
required in ieee80211(9)
before those features can be supported.
The otus
driver also does not currently
support EDCA as this is missing in the NetBSD
network stack. The hooks for it are in the driver code.
