WI(4) BSD Programmer's Manual WI(4)NAMEwi - 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.

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.
