!!DESCRIPTION |
| |

|
| |
|

|
| |
|
26 |
''wavelan'' is the low-level device driver for the NCR / |
| |
|
27 |
AT''WaveLAN ISA__ and Digital (DEC) |
| 3 |
perry |
28 |
__!RoamAbout DS__ wireless ethernet adapter. This driver |
| 1 |
perry |
29 |
is available as a module or might be compiled in the kernel. |
| |
|
30 |
This driver supports multiple cards in both forms (up to 4) |
| |
|
31 |
and allocates the next available ethernet device |
| |
|
32 |
(eth0..eth#) for each card found, unless a device name is |
| |
|
33 |
explicitely specified (see below). This device name will be |
| |
|
34 |
reported in the kernel log file with the MAC address, NWID |
| |
|
35 |
and frequency used by the card. |
| |
|
36 |
!!PARAMETERS |
| |
|
37 |
|
| |
|
38 |
|
| |
|
39 |
This section apply to the module form (parameters passed on |
| |
|
40 |
the insmod(8) command line). If the driver is |
| |
|
41 |
included in the kernel, use the ''ether=IRQ,IO,NAME'' |
| |
|
42 |
syntax on the kernel command line. |
| |
|
43 |
|
| |
|
44 |
|
| |
|
45 |
__io__ |
| |
|
46 |
|
| |
|
47 |
|
| |
|
48 |
Specify the list of base address where to search for wavelan |
| |
|
49 |
cards (setting by dip switch on the card). If you don't |
| |
|
50 |
specify any io address, the driver will scan 0x390 and 0x3E0 |
| |
|
51 |
addresses, which might conflict with other |
| |
|
52 |
hardware... |
| |
|
53 |
|
| |
|
54 |
|
| |
|
55 |
__irq__ |
| |
|
56 |
|
| |
|
57 |
|
| |
|
58 |
Set the list of irq that each wavelan card should use (the |
| |
|
59 |
value is saved in permanent storage for future |
| |
|
60 |
use). |
| |
|
61 |
|
| |
|
62 |
|
| |
|
63 |
__name__ |
| |
|
64 |
|
| |
|
65 |
|
| |
|
66 |
Set the list of name to be used for each wavelan cards |
| |
|
67 |
device (name used by ifconfig(8)). |
| |
|
68 |
!!WIRELESS EXTENSIONS |
| |
|
69 |
|
| |
|
70 |
|
| |
|
71 |
Use iwconfig(8) to manipulate wireless |
| |
|
72 |
extensions. |
| |
|
73 |
|
| |
|
74 |
|
| |
|
75 |
__NWID (or domain)__ |
| |
|
76 |
|
| |
|
77 |
|
| |
|
78 |
Set the network ID [[''0'' to ''FFFF''] or disable it |
| |
|
79 |
[[''off'']. As the NWID is stored in the card Permanent |
| |
|
80 |
Storage Area, it will be reuse at any further invocation of |
| |
|
81 |
the driver. |
| |
|
82 |

|
| |
|

__Frequency __ |
| |
|
85 |
|
| |
|
86 |
|
| |
|
87 |
For the 2.4GHz 2.00 Hardware, you are able to set the |
| |
|
88 |
frequency by specifying one of the 10 defined channels |
| |
|
89 |
(''2.412, 2.422, 2.425, 2.4305, 2.432, 2.442, 2.452, 2.460, |
| |
|
90 |
2.462'' or ''2.484'') or directly by its value. The |
| |
|
91 |
frequency is changed immediately and permanentely. Frequency |
| |
|
92 |
availability depend on the regulations... |
| |
|

__Statistics spy__ |
| |
|
96 |
|
| |
|
97 |
|
| |
|
98 |
Set a list of MAC addresses in the driver (up to 8) and get |
| |
|
99 |
the last quality of link for each of those (see |
| |
|
100 |
iwspy(8)). |
| |
|
101 |
|
| |
|
102 |
|

__/proc/net/wireless__ |
| |
|
104 |
|
| |
|
105 |
|
| |
|
106 |
''status'' is the status reported by the modem. ''Link |
| |
|
107 |
quality'' reports the quality of the modulation on the air |
| |
|
108 |
(direct sequence spread spectrum) [[max = 16]. ''Level'' |
| |
|
109 |
and ''Noise'' refer to the signal level and noise level |
| |
|
110 |
[[max = 64]. The ''crypt discarded packet'' and ''misc |
| |
|
111 |
discarded packet'' counters are not |
| |
|
112 |
implemented. |
| |
|
113 |
!!PRIVATE IOCTL |
| |
|
114 |
|
| |
|
115 |
|
| |
|
116 |
You may use iwpriv(8) to manipulate private |
| |
|
117 |
ioctls. |
| |
|
118 |
|
| |
|
119 |
|

|
120 |
__Quality and Level threshold__ |
| |
|
121 |
|
| |
|
122 |
|
| |
|
123 |
Enable you the define the quality and level threshold used |
| |
|
124 |
by the modem (packet below that level are |
| |
|
125 |
discarded). |
| |
|
126 |
|
| |
|
127 |
|
| |
|
128 |
__Histogram__ |
| |
|
129 |
|
| |
|
130 |
|
| |
|
131 |
This functionality allow to set a number of signal level |
| |
|
132 |
intervals and to count the number of packets received in |
| |
|
133 |
each of those defined intervals. This distribution might be |
| |
|
134 |
used to calculate the mean value and standard deviation of |
| |
|
135 |
the signal level. |
| |
|
136 |
!!SPECIFIC NOTES |
| |
|
137 |
|
| |
|
138 |
|
| |
|
139 |
This driver will fail to detect some __non |
| |
|
140 |
NCR/ATT__ Wavelan cards. If it's your case, |
| |
|
141 |
you must look in the source code on how to add your card to |
| |
|
142 |
the detection routine. |
| |
|
143 |
|
| |
|
144 |
|
| |
|
145 |
Some of the mentioned features are optional. You may enable |
| |
|
146 |
to disable them by changing flags in the driver header and |
| |
|
147 |
recompile. |
