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 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 makes it possible 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.
