11 .TH WAVELAN 4 1996-10-22 "Linux" "Linux Programmer's Manual"
16 wavelan \- AT&T GIS WaveLAN ISA device driver
21 .BI "insmod wavelan_cs.o [io=" B,B.. "] [ irq=" I,I.. "] [name=" N,N.. ]
27 is the low-level device driver for the NCR / AT&T / Lucent
31 wireless ethernet adapter.
32 This driver is available as a module or
33 might be compiled in the kernel.
34 This driver supports multiple cards
35 in both forms (up to 4) and allocates the next available ethernet
36 device (eth0..eth#) for each card found, unless a device name is
37 explicitly specified (see below).
38 This device name will be reported
39 in the kernel log file with the MAC address, NWID and frequency used
45 This section apply to the module form (parameters passed on the
48 If the driver is included in the kernel, use the
50 syntax on the kernel command line.
53 Specify the list of base address where to search for wavelan cards
54 (setting by dip switch on the card).
55 If you don't specify any io
56 address, the driver will scan 0x390 and 0x3E0 addresses, which might
57 conflict with other hardware...
60 Set the list of irq that each wavelan card should use (the value is
61 saved in permanent storage for future use).
64 Set the list of name to be used for each wavelan cards device (name
70 .SS "Wireless Extensions"
73 to manipulate wireless extensions.
82 As the NWID is stored in the card Permanent Storage Area, it will be
83 reuse at any further invocation of the driver.
84 .\" Frequency sub part
85 .SS Frequency & channels
86 For the 2.4GHz 2.00 Hardware, you are able to set the frequency by
87 specifying one of the 10 defined channels
89 .I 2.422, 2.425, 2.4305, 2.432, 2.442, 2.452, 2.460, 2.462
92 or directly by its value.
93 The frequency is changed immediately and
95 Frequency availability depends on the regulations...
98 Set a list of MAC addresses in the driver (up to 8) and get the last
99 quality of link for each of those (see
101 .\" /proc/net/wireless part
102 .SS /proc/net/wireless
104 is the status reported by the modem.
106 reports the quality of the modulation on the air (direct sequence
107 spread spectrum) [max = 16].
111 refer to the signal level and noise level [max = 64].
113 .I crypt discarded packet
115 .I misc discarded packet
116 counters are not implemented.
123 to manipulate private ioctls.
125 .SS Quality and Level threshold
126 Enable you the define the quality and level threshold used by the
127 modem (packet below that level are discarded).
130 This functionality allow to set a number of signal level intervals and
131 to count the number of packets received in each of those defined
133 This distribution might be used to calculate the mean value
134 and standard deviation of the signal level.
139 This driver will fail to detect some
140 .B non-NCR/ATT&T/Lucent
142 If this happens for you, you must look in the source code on
143 how to add your card to the detection routine.
145 Some of the mentioned features are optional.
146 You may enable to disable
147 them by changing flags in the driver header and recompile.
