driver provides support for Aironet Communications 4500 and 4800
wireless network adapters and variants, including the following:
- Aironet Communications 4500 and 4800 series
- Cisco Aironet 340 and 350 series
- Xircom Wireless Ethernet Adapter
Support for these devices include the ISA, PCI and PCMCIA
The Aironet 4500 series adapters operate at 1 and 2Mbps while
the Aironet 4800 series and Cisco adapters 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
The PCMCIA Aironet cards require PC Card support, including the
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.
switch setting is for Plug and Play.)
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 NICs switch settings must agree.
require no switch settings of any kind and will be automatically
probed and attached.
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.
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).
By default, the
driver configures the Aironet card for infrastructure operation.
