wavelan_cs - AT&T GIS WaveLAN PCMCIA device driver
is the low-level Card Services driver for the NCR / AT&T / Lucent
and Digital (DEC)
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
for the card configuration, and reported in the kernel log file with
the MAC address, NWID and frequency used by the card.
Specifies the set of interrupts that may be allocated by this driver.
Sets the access speed of the shared memory window, in nanoseconds.
The default is 0 (i.e., no extra wait states).
Enables or disables roaming mode. The default is 1 (roam).
to manipulate wireless extensions.
Set the operating mode to
This in fact disable or enable roaming support. This setting is not
saved in hardware.
Set the network ID
or disable it
or reenable it
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
2.422, 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
permanentely. Frequency availability depend on the regulations...
Signal level threshold for packet reception
Should be set according to the ambiant noise level.
Set the encryption key
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
is the status reported by the modem.
reports the quality of the modulation on the air (direct sequence
spread spectrum) [max = 16].
refer to the signal level and noise level [max = 64].
crypt discarded packet
misc discarded packet
counters are not implemented.
You may use
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
intervals. 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
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.
