WI(4) Kernel Interfaces Manual WI(4) NAME wi -- Lucent Technologies WaveLAN/IEEE 802.11 PCMCIA driver SYNOPSIS device wi DESCRIPTION The wi driver provides support for WaveLAN/IEEE PCCARD adapters (also known as WaveLAN II cards). Note that while Lucent sells both ISA and PCMCIA WaveLAN/IEEE devices, the ISA product is actually a PCMCIA card in an ISA to PCMCIA bridge adapter. Consequently, the wi driver is required for both the ISA and PCMCIA NICs. Both the original 2Mbps WaveLAN/IEEE cards and the newer 6Mbps WaveLAN/IEEE Turbo adapters are supported. The core of the WaveLAN/IEEE is the Lucent Hermes controller. All host/de- vice interaction is via programmed I/O with the Hermes. The Hermes sup- ports 802.11 and 802.3 frames, power management, BSS, WDS and ad-hoc opera- tion modes. The wi 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 or 2Mbps with auto fallback. For WaveLAN/IEEE Turbo adapters, speeds up to 6Mbps are avail- able. By default, the wi driver configures the WaveLAN card for BSS operation. For more information on configuring this device, see ifconfig(8) DIAGNOSTICS wi%d: init failed The WaveLAN failed to come ready after an initialization command was issued. wi%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. wi%d: device timeout The WaveLAN failed to generate an interrupt to ac- knowledge a transmit command.
