NAME

     atu -- Atmel at76c50x 802.11B wireless network interfaces

SYNOPSIS

     atu* at uhub? port ?

DESCRIPTION

     The atu driver provides support for wireless network adapters based around the Atmel at76c503, at76c503a, at76c505, and at76c505a USB
     chipsets.

     Supported features include 802.11 and 802.3 frames, power management, BSS, IBSS, ad-hoc, and host-based access point mode.

     The atu 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 fixed, 2Mbps fixed, 2Mbps with auto fallback, 5.5Mbps, 8Mbps, or 11Mbps depending on your hardware.

     Four different radio chipsets are used along with the device, each requiring a different firmware.

     By default, the atu driver configures the card for BSS operation (aka infrastructure mode).  This mode requires the use of an access point
     (base station).

     For more information on configuring this device, see ifconfig(8).

     The following devices are among those supported by the atu driver:

	   Acer Peripherals AWL400
	   AcerP AWL-300
	   Aincomm AWU2000B
	   Atmel 2662W-V4
	   Atmel BW002
	   Atmel DWL-120
	   Atmel WL-1330
	   Belkin F5D6050
	   Geowave GW-US11S
	   Linksys WUSB11
	   Linksys WUSB11-V28
	   Ovislink AirLive
	   SMC 2662W-AR

     The atu driver was written by Daan Vreeken and ported to OpenBSD by Theo de Raadt and David Gwynne.  The OpenBSD driver was then ported to
     NetBSD by Jesse Off <joff@NetBSD.org>.

NAME

     an -- Aironet Communications 4500/4800 wireless network adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

           device an
           device wlan

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

           if_an_load="YES"

DESCRIPTION

     The an driver provides support for Aironet Communications 4500 and 4800 wireless network adapters and variants, including the following:

           o   Aironet Communications 4500 and 4800 series
           o   Cisco Aironet 340 and 350 series
           o   Xircom Wireless Ethernet Adapter

     Support for these devices include the ISA, PCI and PCMCIA varieties.  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 support.

     The PCMCIA Aironet cards require PC Card support, including the kernel pccard(4) driver.  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 an 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.

     All host/device interaction with the Aironet cards is via programmed I/O.  The Aironet devices support 802.11 and 802.3 frames, power manage-
     ment, BSS (infrastructure) and IBSS (ad-hoc) operation modes.  The an 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 automati-
     cally chooses the best speed).

     By default, the an driver configures the Aironet card for infrastructure operation.

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

     an%d: init failed  The Aironet card failed to become ready after an initialization command was issued.

     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.

     an%d: device timeout  The Aironet card failed to generate an interrupt to acknowledge a transmit command.
