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 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.

   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  makes  it  possible  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.

   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.
