NAME    [Toc]    [Back]

       wavelan - AT&T GIS WaveLAN ISA device driver

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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 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.

PARAMETERS    [Toc]    [Back]

       This section apply to the module form (parameters passed  on  the  ins-
       mod(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    [Toc]    [Back]

       Use iwconfig(8) to manipulate wireless extensions.

   NWID (or domain)    [Toc]    [Back]
       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 permanentely. Frequency availability
 depend on the regulations...

   Statistics spy    [Toc]    [Back]
       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    [Toc]    [Back]

       You may use iwpriv(8) to manipulate private ioctls.

   Quality and Level threshold    [Toc]    [Back]
       Enable you the define the quality and level threshold used by the modem
       (packet below that level are discarded).

   Histogram    [Toc]    [Back]
       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.

SPECIFIC NOTES    [Toc]    [Back]

       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 routine.

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