+Aironet Communications 4500/4800 wireless network adapter driver
+.Sh SYNOPSIS
+.Cd "wi* at pcmcia? function ?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for Aironet Communications 4500 and 4800
+wireless network adapters.
+This includes the ISA, PCI and PCMCIA
+varieties.
+The 4500 series adapters operate at 1 and 2Mbps while
+the 4800 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 no not require any PCMCIA
+support.
+.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
+.Nm
+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.
+.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
+.Nm
+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).
+.Pp
+By default, the
+.Nm
+driver configures the Aironet card to join an access point with an SSID
+of null string.
+For adhoc mode, in which
+stations can communicate among each other without the aid of an access
+point, the driver must be set using
+.Xr ifconfig 8 .
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8
+and
+.Xr ifmedia 4 .

+.Nm
+driver include:

+.Sh DIAGNOSTICS
+.Bl -diag
+.It "an%d: init failed"
+The Aironet card failed to come ready after an initialization command was
+issued.
+.It "an%d: failed to allocate %d bytes on NIC"
+The driver was unable to allocate memory for transmit frames in the
+NIC's on-board RAM.
+.It "an%d: device timeout"
+The Aironet card failed to generate an interrupt to acknowledge a transmit
+command.
