  11 .TH WAVELAN 4 1996-10-22 "Linux" "Linux Programmer's Manual"
  12 .SH NAME
  13 wavelan \- AT&T GIS WaveLAN ISA device driver
  14 .SH SYNOPSIS
  15 .BI "insmod wavelan_cs.o [io=" B,B.. "] [ irq=" I,I.. "] [name=" N,N.. ]
  16 .SH DESCRIPTION
  17 .I wavelan
  18 is the low-level device driver for the NCR / AT&T / Lucent
  19 .B WaveLAN ISA
  20 and Digital (DEC)
  21 .B RoamAbout DS
  22 wireless ethernet adapter.
  23 This driver is available as a module or
  24 might be compiled in the kernel.
  25 This driver supports multiple cards
  26 in both forms (up to 4) and allocates the next available ethernet
  27 device (eth0..eth#) for each card found, unless a device name is
  28 explicitly specified (see below).
  29 This device name will be reported
  30 in the kernel log file with the MAC address, NWID and frequency used
  31 by the card.
  32 .SS Parameters
  33 This section apply to the module form (parameters passed on the
  34 .BR insmod (8)
  35 command line).
  36 If the driver is included in the kernel, use the
  37 .I ether=IRQ,IO,NAME
  38 syntax on the kernel command line.
  39 .TP
  40 .B io
  41 Specify the list of base address where to search for wavelan cards
  42 (setting by dip switch on the card).
  43 If you don't specify any io
  44 address, the driver will scan 0x390 and 0x3E0 addresses, which might
  45 conflict with other hardware...
  46 .TP
  47 .B irq
  48 Set the list of irq that each wavelan card should use (the value is
  49 saved in permanent storage for future use).
  50 .TP
  51 .B name
  52 Set the list of name to be used for each wavelan cards device (name
  53 used by
  54 .BR ifconfig (8)).
  55 .SS Wireless extensions
  56 Use
  57 .BR iwconfig (8)
  58 to manipulate wireless extensions.
  59 .SS NWID (or domain)
  60 Set the network ID
  61 .RI [ 0
  62 to
  63 .IR FFFF ]
  64 or disable it
  65 .RI [ off ].
  66 As the NWID is stored in the card Permanent Storage Area, it will be
  67 reuse at any further invocation of the driver.
  68 .SS Frequency & channels
  69 For the 2.4GHz 2.00 Hardware, you are able to set the frequency by
  70 specifying one of the 10 defined channels
  71 .RI ( 2.412,
  72 .I 2.422, 2.425, 2.4305, 2.432, 2.442, 2.452, 2.460, 2.462
  73 or
  74 .IR 2.484 )
  75 or directly by its value.
  76 The frequency is changed immediately and
  77 permanently.
  78 Frequency availability depends on the regulations...
  79 .SS Statistics spy
  80 Set a list of MAC addresses in the driver (up to 8) and get the last
  81 quality of link for each of those (see
  82 .BR iwspy (8)).
  83 .SS /proc/net/wireless
  84 .I status
  85 is the status reported by the modem.
  86 .I Link quality
  87 reports the quality of the modulation on the air (direct sequence
  88 spread spectrum) [max = 16].
  89 .I Level
  90 and
  91 .I Noise
  92 refer to the signal level and noise level [max = 64].
  93 The
  94 .I crypt discarded packet
  95 and
  96 .I misc discarded packet
  97 counters are not implemented.
  98 .SS Private ioctl
  99 You may use
 100 .BR iwpriv (8)
 101 to manipulate private ioctls.
 102 .SS Quality and level threshold
 103 Enable you the define the quality and level threshold used by the
 104 modem (packet below that level are discarded).
 105 .SS Histogram
 106 This functionality makes it possible to set a number of
 107 signal level intervals and
 108 to count the number of packets received in each of those defined
 109 intervals.
 110 This distribution might be used to calculate the mean value
 111 and standard deviation of the signal level.
 112 .SS Specific notes
 113 This driver will fail to detect some
 114 .B non-NCR/ATT&T/Lucent
 115 Wavelan cards.
 116 If this happens for you, you must look in the source code on
 117 how to add your card to the detection routine.
 118 .PP
 119 Some of the mentioned features are optional.
 120 You may enable to disable
 121 them by changing flags in the driver header and recompile.
