wavelan - AT&T GIS WaveLAN ISA device driver
insmod wavelan_cs.o [io=B,B..] [ irq=I,I..]
is the low-level device driver for the NCR / AT&T / Lucent
and Digital (DEC) RoamAbout DS
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.
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
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 hardware...
- Set the list of irq that each wavelan card should use (the
value is saved in permanent storage for future use).
- Set the list of name to be used for each wavelan cards
device (name used by ifconfig(8)).
to manipulate wireless extensions.
NWID (or domain)¶
Set the network ID [0
] 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 directly by its value. The
frequency is changed immediately and permanently. Frequency availability
depends 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 iwspy(8)
is the status reported by the modem. Link quality
the quality of the modulation on the air (direct sequence spread spectrum)
[max = 16]. Level
refer to the signal level and noise
level [max = 64]. The crypt discarded packet
and misc discarded
counters are not implemented.
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 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.
This driver will fail to detect some non-NCR/ATT&T/Lucent
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.
