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 fur-
       ther 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
       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 spec-
       trum) [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 signal level.

SPECIFIC NOTES

       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.
