NAME

6       wavelan - AT&T GIS WaveLAN ISA device driver
7

SYNOPSIS

9       insmod wavelan_cs.o [io=B,B..] [ irq=I,I..] [name=N,N..]
10

DESCRIPTION

12       wavelan  is  the  low-level  device  driver for the NCR / AT&T / Lucent
13       WaveLAN ISA and Digital (DEC) RoamAbout DS wireless  ethernet  adapter.
14       This  driver  is available as a module or might be compiled in the ker‐
15       nel. This driver supports multiple cards in both forms (up  to  4)  and
16       allocates the next available ethernet device (eth0..eth#) for each card
17       found, unless a device name is explicitly specified (see  below).  This
18       device  name  will  be  reported  in  the  kernel log file with the MAC
19       address, NWID and frequency used by the card.

PARAMETERS

22       This section apply to the module form (parameters passed  on  the  ins‐
23       mod(8)  command line). If the driver is included in the kernel, use the
24       ether=IRQ,IO,NAME syntax on the kernel command line.
25
26       io     Specify the list of base address where  to  search  for  wavelan
27              cards  (setting by dip switch on the card). If you don't specify
28              any io address, the driver will scan 0x390 and 0x3E0  addresses,
29              which might conflict with other hardware...
30
31       irq    Set the list of irq that each wavelan card should use (the value
32              is saved in permanent storage for future use).
33
34       name   Set the list of name to be used for each  wavelan  cards  device
35              (name used by ifconfig(8)).
36

WIRELESS EXTENSIONS

38       Use iwconfig(8) to manipulate wireless extensions.
39
40   NWID (or domain)
41       Set  the  network  ID  [0 to FFFF] or disable it [off].  As the NWID is
42       stored in the card Permanent Storage Area, it will be reuse at any fur‐
43       ther invocation of the driver.
44
45   Frequency & channels
46       For  the  2.4GHz  2.00  Hardware,  you are able to set the frequency by
47       specifying one of the 10 defined channels (2.412, 2.422, 2.425, 2.4305,
48       2.432,  2.442,  2.452, 2.460, 2.462 or 2.484) or directly by its value.
49       The frequency is changed immediately and permanently.  Frequency avail‐
50       ability depends on the regulations...
51
52   Statistics spy
53       Set  a  list  of MAC addresses in the driver (up to 8) and get the last
54       quality of link for each of those (see iwspy(8)).
55
56   /proc/net/wireless
57       status is the status reported by the modem.  Link quality  reports  the
58       quality  of the modulation on the air (direct sequence spread spectrum)
59       [max = 16].  Level and Noise refer to the signal level and noise  level
60       [max = 64].  The crypt discarded packet and misc discarded packet coun‐
61       ters are not implemented.
62

PRIVATE IOCTL

64       You may use iwpriv(8) to manipulate private ioctls.
65
66   Quality and Level threshold
67       Enable you the define the quality and level threshold used by the modem
68       (packet below that level are discarded).
69
70   Histogram
71       This  functionality allow to set a number of signal level intervals and
72       to count the number of packets received in each of those defined inter‐
73       vals.  This  distribution might be used to calculate the mean value and
74       standard deviation of the signal level.
75

SPECIFIC NOTES

77       This driver will fail  to  detect  some  non  NCR/ATT&T/Lucent  Wavelan
78       cards.  If  it's  your case, you must look in the source code on how to
79       add your card to the detection routine.
80
81       Some of the mentioned features are optional. You may enable to  disable
82       them by changing flags in the driver header and recompile.
