<p class="Pp">The <code class="Nm">upgt</code> driver supports the USB 2.0
Conexant/Intersil PrismGT series wireless adapters based on the GW3887
chipset.</p>
<p class="Pp">These are the modes the <code class="Nm">upgt</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">upgt</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. The
<code class="Nm">upgt</code> driver relies on the software 802.11 stack for
both encryption and decryption of data frames.</p>
<p class="Pp">The <code class="Nm">upgt</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>

devices (GW3887 chipset) but not the USB 1.0 devices containing the NET2280,
ISL3880, and ISL3886 chipsets. Some further efforts would be necessary to
add USB 1.0 support to the driver.</p>
