NAMEwavelan_cs - AT&T GIS WaveLAN PCMCIA device driver
SYNOPSISinsmod wavelan_cs.o [irq_list=i,j,...] [mem_speed=n] [do_roaming=n]
DESCRIPTIONwavelan_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 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).
WIRELESS EXTENSIONSUse iwconfig(8) to manipulate wireless extensions.
ModeSet the operating mode to Ad-Hoc or Managed. This in fact disable or enable roaming support. This setting is not saved in hardware.
Network IDSet 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 & channelsFor 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...
SensitivitySignal level threshold for packet reception [0 to 63]. Should be set according to the ambiant noise level.
Encryption keySet 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).
Statistics spySet 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/wirelessstatus 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 IOCTLYou may use iwpriv(8) to manipulate private ioctls.
Quality thresholdEnable you the define the quality threshold used by the modem (packet below that level are discarded).
HistogramThis 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.
OTHER FEATURESHot unplug support.
Power saving (use 'ifconfig down').
SPECIFIC NOTESThis 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.
