IEEE 802.11a/g/n wireless network device</span></p>

<p class="Pp">The <code class="Nm">otus</code> driver supports USB 2.0 wireless
network devices based on Atheros Communications AR9001U chipset.</p>
<p class="Pp">The AR9001U chipset is made of an AR9170 MAC/Baseband and an
AR9101 (1T2R), AR9102 (2T2R) or AR9104 (dual-band 2T2R) Radio.</p>
<p class="Pp">These are the modes the <code class="Nm">otus</code> driver can
operate in:</p>
<dl class="Bl-tag">
<dt id="infrastructure">BSS mode</dt>
<dd>Also known as
<a class="permalink" href="#infrastructure"><i class="Em">infrastructure</i></a>
mode, this is used when associating with an access point, through which
all traffic passes. This mode is the default.</dd>
<dt>monitor mode</dt>
<dd>In this mode the driver is able to receive packets without associating
with an access point. This disables the internal receive filter and
enables the card to capture packets from networks which it wouldn't
normally have access to, or to scan for access points.</dd>
</dl>
<p class="Pp">The <code class="Nm">otus</code> 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.</p>
<p class="Pp">The <code class="Nm">otus</code> driver can be configured at
runtime with <a class="Xr">ifconfig(8)</a> or on boot with
<a class="Xr">ifconfig.if(5)</a>.</p>
</section>
<section class="Sh">
<h1 class="Sh" id="FILES"><a class="permalink" href="#FILES">FILES</a></h1>
<p class="Pp">The driver needs at least version 1.0 of the following firmware
files, which are loaded when an interface is attached:</p>

usage is restricted.</p>

<p class="Pp">The AVM FRITZ!WLAN USB Stick N adapter is currently not
supported.</p>
<p class="Pp">The <code class="Nm">otus</code> driver does not support any of

required in <a class="Xr">ieee80211(9)</a> before those features can be
supported.</p>
<p class="Pp">The <code class="Nm">otus</code> driver also does not currently
support EDCA as this is missing in the <span class="Ux">NetBSD</span>
network stack. The hooks for it are in the driver code.</p>
