.Sh NAME

.Nm an
|
|
.Nd "Aironet Communications 4500/4800 wireless network adapter driver"
|
|
.Sh SYNOPSIS
|
|
.Cd "device an"
|
|
.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 do not require any PCCARD
|
|
support.
|
|
.Pp
|
|
The PCMCIA Aironet cards require pccard support, including the
|
|
kernel pccard driver support and the
|
|
.Xr pccardd 8
|
|
daemon.
|
|
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 for infrastructure operation.
|
|
.Pp

|

|
|
.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.
