<p class="Pp">The <code class="Nm">an</code> driver provides support for Aironet
Communications 4500/4800 and Cisco Aironet 340/350 series wireless network
adapters. This includes the ISA, PCI and PCMCIA varieties. The 4500 series
adapters operate at 1 and 2Mbps while the 4800 series and 340/350 series can
operate at 1, 2, 5.5 and 11Mbps. The ISA, PCI and PCMCIA devices are all
based on the same core PCMCIA modules and all have the same programming
interface, however unlike the Lucent WaveLAN/IEEE cards, the ISA and PCI
cards appear to the host as normal ISA and PCI devices and do not require
any PCMCIA support.</p>
<p class="Pp">The PCMCIA Aironet cards require PCMCIA support. ISA cards can
either be configured to use ISA Plug and Play or to use a particular I/O
address and IRQ by properly setting the DIP switches on the board. (The
default switch setting is for plug and play.) The <code class="Nm">an</code>
driver has Plug and Play support and will work in either configuration,
however when using a hard-wired I/O address and IRQ, the driver
configuration and the NIC's switch settings must agree. PCI cards require no
switch settings of any kind and will be automatically probed and
attached.</p>
<p class="Pp">All host/device interaction with the Aironet cards is via
programmed I/O. The Aironet devices support 802.11 and 802.3 frames, power
management, BSS (infrastructure) and IBSS (ad-hoc) operation modes. The
<code class="Nm">an</code> driver encapsulates all IP and ARP traffic as
802.11 frames, however it can receive either 802.11 or 802.3 frames.
Transmit speed is selectable between 1Mbps, 2Mbps, 5.5Mbps, 11Mbps, or
“auto” (the NIC automatically chooses the best speed).</p>
<p class="Pp">By default, the <code class="Nm">an</code> driver configures the
Aironet card to join an access point with an SSID of null string. For ad-hoc
mode, in which stations can communicate among each other without the aid of
an access point, the driver must be set using
<a class="Xr">ifconfig(8)</a>.</p>
<p class="Pp">For more information on configuring this device, see
<a class="Xr">ifconfig(8)</a> and <a class="Xr">ifmedia(4)</a>.</p>
