wavelan - AT&T GIS WaveLAN ISA device driver
insmod wavelan_cs.o [io=B,B..] [ irq=I,I..] [name=N,N..
wavelan is the low-level device driver for the NCR / AT&T /
Lucent 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 multi-
ple 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
io 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
irq Set the list of irq that each wavelan card should use
(the value is saved in permanent storage for future
name Set the list of name to be used for each wavelan cards
device (name used by ifconfig(8)).
Use iwconfig(8) to manipulate wireless extensions.
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 the driver.
Frequency & channels
For the 2.4GHz 2.00 Hardware, you are able to set the fre-
quency by specifying one of the 10 defined channels (2.412,
2.422, 2.425, 2.4305, 2.432, 2.442, 2.452, or 2.484) or
directly by its value. The frequency is changed immediately
and permanentely. Frequency availability depend on the regu-
Set a list of MAC addresses in the driver (up to 8) and get
the last quality of link for each of those (see iwspy(8)).
status is the status reported by the modem. Link quality
reports the quality of the modulation on the air (direct
sequence spread spectrum) [max = 16]. Level and Noise refer
to the signal level and noise level [max = 64]. The crypt
discarded packet and misc discarded packet counters are not
You may use iwpriv(8) to manipulate private ioctls.
Quality and Level threshold
Enable you the define the quality and level threshold used
by the modem (packet below that level are discarded).
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&T/Lucent
Wavelan cards. If it's your case, you must look in the
source code on how to add your card to the detection rou-
Some of the mentioned features are optional. You may enable
to disable them by changing flags in the driver header and
