Name
wavelan — AT&T GIS WaveLAN ISA device driver .\"
.\" SYNOPSIS part .\"
DESCRIPTION
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 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 explicitly
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.
Parameters
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.
- 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 other hardware...
- irq
-
Set the list of irq that each wavelan card should
use (the value is saved in permanent storage for
future use).
- name
-
Set the list of name to be used for each wavelan
cards device (name used by ifconfig(8)).
Wireless Extensions
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
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
permanently. Frequency availability depends on the
regulations...
Statistics spy
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)).
/proc/net/wireless
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 implemented.
Private Ioctl
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).
Histogram
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.
Specific Notes
This driver will fail to detect some non NCR/ATT&T/Lucent Wavelan
cards. If this happens for you, 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 recompile.
