WAVELAN(4)                                             WAVELAN(4)

       wavelan - AT&T GIS WaveLAN ISA device driver

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

       wavelan  is the low-level device driver for the NCR / AT&T
       / Lucent WaveLAN ISA and Digital (DEC) RoamAbout DS  wire-
       less  ethernet adapter. This driver is available as a mod-
       ule or might be compiled in the kernel. This  driver  sup-
       ports 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 explicitely specified
       (see below). This device name will be reported in the ker-
       nel log file with the MAC address, NWID and frequency used
       by the card.

       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)).

       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 fre-
       quency  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 availabil-
       ity depend 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

       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.

       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).

       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.

       This  driver will fail to detect 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 rou-

       Some of the  mentioned  features  are  optional.  You  may
       enable  to  disable  them  by changing flags in the driver
       header and recompile.
