wavelan_cs - AT&T GIS WaveLAN PCMCIA device driver
insmod wavelan_cs.o [irq_list=i,j,...] [mem_speed=n] [do_roaming=n]
wavelan_cs is the low-level Card Services driver for the NCR / AT&T /
Lucent WaveLAN PCMCIA and Digital (DEC) RoamAbout DS wireless ethernet
adapter. When this driver is attached to a card, it allocates the next
available ethernet device (eth0..eth#). This device name will be
passed on to cardmgr(8) for the card configuration, and reported in the
kernel log file with the MAC address, NWID and frequency used by the
Specifies the set of interrupts that may be allocated by this
Sets the access speed of the shared memory window, in nanosec-
onds. The default is 0 (i.e., no extra wait states).
Enables or disables roaming mode. The default is 1 (roam).
Use iwconfig(8) to manipulate wireless extensions.
Set the operating mode to Ad-Hoc or Managed. This in fact disable or
enable roaming support. This setting is not saved in hardware.
Set the network ID [0 to FFFF] or disable it [off] or reenable it [on].
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 permanentely. Frequency avail-
ability depend on the regulations...
Signal level threshold for packet reception [0 to 63]. Should be set
according to the ambiant noise level.
Set the encryption key [0 to FFFF-FFFF-FFFF-FFFF]. Use [off] and [on]
to disable and reenable the hardware encryption. This feature works
only for device with encryption option (DES or AES).
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 coun-
ters are not implemented.
You may use iwpriv(8) to manipulate private ioctls.
Enable you the define the quality 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 inter-
vals. This distribution might be used to calculate the mean value and
standard deviation of the signal level.
Hot unplug support.
Power saving (use 'ifconfig down').
This driver will fail to load 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.
This man page describes the standalone PCMCIA drivers provided by the
pcmcia-cs source, not the PCMCIA kernel driver support that is included
in the 2.4 (and later) linux kernel. While the kernel PCMCIA code has
the same functionality as the driver side of the standalone PCMCIA
package, there are some important differences. Therefore, some or all
of this documentation might not apply to the kernel drivers.
