wavelan is the low-level device driver for the NCR /
AT''WaveLAN ISA and Digital (DEC)
!RoamAbout? DS__ wireless ethernet adapter. This driver
is available as a module or might be compiled in the kernel.
This driver supports multiple cards in both forms (up to 4)
and allocates the next available ethernet device
(eth0..eth#) for each card found, unless a device name is
explicitely specified (see below). This device name will be
reported in the kernel log file with the MAC address, NWID
and frequency used by the card.
This section apply to the module form (parameters passed on
the insmod(8) command line). If the driver is
included in the kernel, use the ether=IRQ,IO,NAME
syntax on the kernel command line.
Specify the list of base address where to search for wavelan
cards (setting by dip switch on the card). If you don't
specify any io address, the driver will scan 0x390 and 0x3E0
addresses, which might conflict with other
Set the list of irq that each wavelan card should use (the
value is saved in permanent storage for future
Set the list of name to be used for each wavelan cards
device (name used by ifconfig(8)).
Use iwconfig(8)? to manipulate wireless
NWID (or domain)
Set the network ID [''0'' to ''FFFF''? or disable it
[''off''?. As the NWID is stored in the card Permanent
Storage Area, it will be reuse at any further invocation of
For the 2.4GHz 2.00 Hardware, you are able to set the
frequency by specifying one of the 10 defined channels
(2.412, 2.422, 2.425, 2.4305, 2.432, 2.442, 2.452, 2.460,
2.462 or 2.484) or directly by its value. The
frequency is changed immediately and permanentely. Frequency
availability depend on the regulations...
Set a list of MAC addresses in the driver (up to 8) and get
the last quality of link for each of those (see

quality reports the quality of the modulation on the air

discarded packet counters are not
You may use iwpriv(8)? to manipulate private

This functionality allow to set a number of signal level
intervals and to count the number of packets received in
each of those defined intervals. This distribution might be
used to calculate the mean value and standard deviation of
the signal level.
This driver will fail to detect some non
NCR/ATT Wavelan cards. If it's your case,
you must look in the source code on how to add your card to
the detection routine.
Some of the mentioned features are optional. You may enable
to disable them by changing flags in the driver header and
