otus
— Atheros USB
IEEE 802.11a/b/g/n wireless network device
otus* at uhub? port ?
The 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 (WPA1 and WPA2).
WPA2 is the current encryption standard for wireless networks. It is
strongly recommended that neither WEP nor WPA1 are used as the sole
mechanism to secure wireless communication, due to serious weaknesses. WPA1
is disabled by default and may be enabled using the option
"wpaprotos
wpa1,wpa2". For standard WPA networks which use
pre-shared keys (PSK), keys are configured using the
"wpakey
" option. WPA-Enterprise networks
require use of the wpa_supplicant package.

The otus
driver can be configured at
runtime with ifconfig(8) or on boot
with hostname.if(5).
The driver needs at least version 1.0 of the following firmware files, which are loaded when an interface is attached:
Although these firmware files are freely redistributable, their usage is restricted. A prepackaged version of the firmware can be installed using fw_update(8).
The following adapters should work:
The following example scans for available networks:
# ifconfig otus0 scan
The following hostname.if(5) example configures otus0 to join network “mynwid”, using WPA key “mywpakey”, obtaining an IP address using DHCP:
join mynwid wpakey mywpakey inet autoconf
arp(4), ifmedia(4), intro(4), netintro(4), usb(4), hostname.if(5), ifconfig(8)
The otus
driver first appeared in
OpenBSD 4.6.
The otus
driver was written by
Damien Bergamini
<damien.bergamini@free.fr>
based on source code licensed under the ISC released in 2008 by Atheros
Communications for Linux.
The AVM FRITZ!WLAN USB Stick N adapter is currently not supported.
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.
This driver does not support powersave mode.
