WAVELAN(4)                                          Linux Programmer's Manual                                         WAVELAN(4)



NAME
       wavelan - AT&T GIS WaveLAN ISA device driver

SYNOPSIS
       insmod wavelan_cs.o [io=B,B..] [ irq=I,I..] [name=N,N..]

DESCRIPTION
       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  multi-
       ple  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.

   Parameters
       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.

       io     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...

       irq    Set the list of irq that each wavelan card should use (the value is saved in permanent storage for future use).

       name   Set the list of name to be used for each wavelan cards device (name used by ifconfig(8)).

   Wireless Extensions
       Use iwconfig(8) to manipulate wireless extensions.

   NWID (or domain)
       Set the network ID [0 to FFFF] 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 2.484) or directly by its value.   The  frequency  is  changed
       immediately and permanently.  Frequency availability depends on the regulations...

   Statistics spy
       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)).

   /proc/net/wireless
       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.

   Private Ioctl
       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).

   Histogram
       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  sig-
       nal level.

   Specific Notes
       This  driver  will fail to detect some non-NCR/ATT&T/Lucent Wavelan 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.
