NAME
     wi - Lucent Technologies WaveLAN/IEEE 802.11 PCMCIA driver

SYNOPSIS
     wi0 at pcmcia?

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 11Mbps WaveLAN/IEEE Turbo adapters are supported.

     802.11 parameters can be set using the ifconfig(8) utility.

     The frequencies available for a card depend on the region depend on the
     region for which the card is manufactured because of radio regulations
     specified by regional authorities. Recognized regulatory authorities in-
     clude the FCC (United States), ETSI (Europe), France and Japan. Frequen-
     cies in the table are specified in Mhz.

	   13		 -	2472	2472	  2472
	   14		 -	-	-	  2484

     Note that older Japanese cards only support channel 14.

     If an illegal channel is specified, the NIC will revert to its default
     channel. For NICs sold in the United States and Europe, the default chan-
     nel is 3. For NICs sold in France, the default channel is 11. For NICs
     sold in Japan, the only available channel is 14.  Note that two stations
     must be set to the same channel in order to communicate.

DIAGNOSTICS
     wi%d: init failed	The WaveLAN failed to come ready after an initializa-
     tion command was issued.

     wi%d: failed to allocate %d bytes on NIC  The driver was unable to allo-
     cate memory for transmit frames in the NIC's on-board RAM.

     wd%d: device timeout  The WaveLAN failed to generate an interrupt to ac-
     knowledge a transmit command.
