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.
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 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)).
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...
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.
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 routine.
Some of the mentioned features are optional. You may enable to disable them by
changing flags in the driver header and recompile.
