39: ** 1.
40:  Q: How to install WiFi driver?**
41: *** Step 1: Check WiFi hardware
42: 
43: {{{
44:    # prtconf -pv
45: }}}
46: 
47:  You can grep "pciclass, 028000" for WiFi card’s vendor id, and device id; To check [[compatible list>>Community Group laptop.wireless_driver_compatible_list]] to make sure it is supported.
48:  You can also read information from scanpci output directly to check if the hardware is supported or not:
49: 
50: {{{
51:    # /usr/X11/bin/scanpci -v
52: }}}
53: 
54: *** Step 2: Choose right driver & right versions according to the [[compatible list>>Community Group laptop.wireless_driver_compatible_list]] ;
55: *** Step 3: Install driver by specific command:
56: 
57: {{{
58:    # cp driver_32bit /kernel/drv
59:    # cp driver_64bit /kernel/drv/amd64
60:    # add_drv -i ’"pcixxxx,xxxx"’ driver_name
61: }}}
62: 
63:  or, install driver by pkgadd command:
64: 
65: {{{
66:    # pkgadd -d . SUNWxxxx
67: }}}
68: 
69: [[top>>#0]][[ opensolaris wireless >>Community Group laptop.wireless]]
70: ** 2.
71:  Q: My laptop has WiFi driver installed, how come it doesn’t work?**
72: *** Make sure driver is correctly installed by:
73: 
74: {{{
75:    # modinfo | grep [driver_name]
76: }}}
77: 
78:  Also, run devfsadm to make sure a link to WiFi interface is created under /dev:
79: 
80: {{{
81:    # devfsadm -i [driver_name]
82: }}}
83: 
84: *** Do not forget plumb interface:
85: 
86: {{{
87:    # ifconfig [WiFi_interface] plumb
88: }}}
89: 
90: *** Make sure radio switch is ON. It is very easy to be neglected. Although wificonfig support get radio status, but not all drivers support this feature. For ipw and iwi drivers, you can try:
91: 
92: {{{
93:    # wificonfig getparam radio
94: }}}
95: 
96: *** If you are using build(snv_62+), you can try GUI tool nwam. The usability is friendly. Initiate it, by:
97: 
98: {{{
99:    # svcadm disable svc:/network/physical:default
100:    # svcadm enable svc:/network/physical:nwam
101: }}}
102: 
103: *** If GUI doesn’t work, or you run earlier build, or you want to try command line tools(dladm), you can try some basic commands:
104: 
105: {{{
106:    # svcadm disable nwam /* disable nwam firstly */
107:    # dladm scan-wifi
108:    # dladm show-wifi
109: }}}
110: 
111:  For WEP/WPA network, please create security object first:
112: 
113: {{{
114:    # dladm create-secobj -c wep/wpa [key_name]
115:    ...input key here...
116: }}}
117: 
118:  Then, you can connect to a specific AP:
119: 
120: {{{
121:    # dladm connect-wifi -e [essid_name] -k [key_name] [WiFi_interface]
122: }}}
123: 
124:  for other scenario, dladm manpage has more detailed information.
125: *** The other command line tool, wificonfig, can be used as well:
126: 
127: {{{
128:    # wificonfig -i [WiFi_interface] scan
129: }}}
130: 
131:  wificonfig support profile, so user can connect to specific profile directly:
132: 
133: {{{
134:    # wificonfig createprofile [myprofile_name] essid=[essid_name] encryption=wep wepkey1=[key]
135:    # wificonfig -i [WiFi_interface] connect [myprofile_name]
136: }}}
137: 
138:  for more usage, please refer to wificonfig manage.

190:  When this section was written, WPA was not supported. So for setting WPA, you still need to {{code}}# man dladm{{/code}} and check {{code}}dladm create-secobj{{/code}} section.
191:  Detailed info about nwam is on opensolaris.org:
192: [[http://opensolaris.org/os/project/nwam/>>Project nwam.WebHome]]
193:  Currently phase 0 has been integrated into OpenSolairs b62.
194: *** Wificonfig is going to be obsolete. But as it’s the first WiFi configuration tool and has been there for years, many GUI tools, like inetmenu and the network admin panel, are developed on its basis. The available doc is {{code}}# man wificonfig{{/code}}.
