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 SEE ALSO

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>. BSD

NAME
an -- Aironet 4500/4800 and Cisco 340/350 series wireless network driver SYNOPSIS
an* at pcmcia? function ? an* at pci? dev ? function ? an* at isapnp? DESCRIPTION
The an 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 pro- gramming 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. 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 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 automat- ically chooses the best speed). By default, the an driver configures the Aironet card to join an access point with an SSID of null string. For ad-hoc mode, in which sta- tions can communicate among each other without the aid of an access point, the driver must be set using ifconfig(8). For more information on configuring this device, see ifconfig(8) and ifmedia(4). HARDWARE
Cards supported by the an driver include: Aironet 4500 Series Aironet 4800 Series Cisco Aironet 340 Series Cisco Aironet 350 Series DIAGNOSTICS
an%d: init failed The Aironet card failed to come 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.
