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 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 explicitely 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.


     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

     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,  or  2.484)  or
     directly  by its value. The frequency is changed immediately
     and permanentely. Frequency availability depend on the regu-

  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)).

     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


     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
