12 | .SH NAME |
13 | wavelan \- AT&T GIS WaveLAN ISA device driver | |
fea681da MK |
14 | .SH SYNOPSIS |
15 | .BI "insmod wavelan_cs.o [io=" B,B.. "] [ irq=" I,I.. "] [name=" N,N.. ] | |
fea681da MK |
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 | |
c13182ef MK |
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 | |
fea681da MK |
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 | |
c13182ef MK |
28 | explicitly specified (see below). |
29 | This device name will be reported | |
fea681da MK |
30 | in the kernel log file with the MAC address, NWID and frequency used |
31 | by the card. | |
2b2581ee | 32 | .SS Parameters |
fea681da MK |
33 | This section apply to the module form (parameters passed on the |
34 | .BR insmod (8) | |
c13182ef MK |
35 | command line). |
36 | If the driver is included in the kernel, use the | |
fea681da MK |
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 | |
c13182ef MK |
42 | (setting by dip switch on the card). |
43 | If you don't specify any io | |
fea681da MK |
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)). | |
c634028a | 55 | .SS "Wireless extensions" |
fea681da MK |
56 | Use |
57 | .BR iwconfig (8) | |
58 | to manipulate wireless extensions. | |
fea681da | 59 | .SS NWID (or domain) |
c13182ef | 60 | Set the network ID |
fea681da MK |
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. | |
fea681da MK |
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 ) | |
c13182ef MK |
75 | or directly by its value. |
76 | The frequency is changed immediately and | |
17490d2f MK |
77 | permanently. |
78 | Frequency availability depends on the regulations... | |
fea681da MK |
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)). | |
fea681da MK |
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. | |
c634028a | 98 | .SS "Private ioctl" |
fea681da MK |
99 | You may use |
100 | .BR iwpriv (8) | |
101 | to manipulate private ioctls. | |
c634028a | 102 | .SS Quality and level threshold |
fea681da MK |
103 | Enable you the define the quality and level threshold used by the |
104 | modem (packet below that level are discarded). | |
fea681da | 105 | .SS Histogram |
75d33b2a MK |
106 | This functionality makes it possible to set a number of |
107 | signal level intervals and | |
fea681da | 108 | to count the number of packets received in each of those defined |
c13182ef MK |
109 | intervals. |
110 | This distribution might be used to calculate the mean value | |
fea681da | 111 | and standard deviation of the signal level. |
c634028a | 112 | .SS "Specific notes" |
fea681da | 113 | This driver will fail to detect some |
c382a365 | 114 | .B non-NCR/ATT&T/Lucent |
c13182ef | 115 | Wavelan cards. |
3758f6da | 116 | If this happens for you, you must look in the source code on |
fea681da MK |
117 | how to add your card to the detection routine. |
118 | .PP | |
c13182ef MK |
119 | Some of the mentioned features are optional. |
120 | You may enable to disable | |
fea681da | 121 | them by changing flags in the driver header and recompile. |
