Before You Begin
Perform the following steps to connect your laptop to a WiFi network.
For more information, see How to Use Your Assigned Administrative Rights in Oracle Solaris 11.1 Administration: Security Services.
# dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE net0 Ethernet up 1500 full ath0 net1 Ethernet up 1500 full e1000g0
In this example, the output indicates that two links are available. Net0 over the device ath0 link supports WiFi communications. The e1000g0 link serves to connect the system to a wired network.
Use the following steps to configure the interface:
# ipadm create-ip net0
# ipadm show-if IFNAME CLASS STATE ACTIVE OVER lo0 loopback ok yes -- net0 ip ok yes --
# dladm scan-wifi LINK ESSID BSSID/IBSSID SEC STRENGTH MODE SPEED net0 ofc 00:0e:38:49:01:d0 none good g 54Mb net0 home 00:0e:38:49:02:f0 none very weak g 54Mb net0 linksys 00:0d:ed:a5:47:e0 none very good g 54Mb
The example output of the scan-wifi command displays information about the available WiFi networks at the current location. The information in the output includes:
Refers to the link name to be used in the WiFi connection.
Refers to the Extended Service Set ID. The ESSID is the name of the WiFi network, which can be randomly named by the administrator of the specific wireless network.
Refers to the Basic Service Set ID, the unique identifier for a particular ESSID. The BSSID is the 48-bit MAC address of the nearby access point that serves the network with a particular ESSID.
Refers to the type of security that is needed to access the network. The values are none or WEP. For information about WEP, refer to Secure WiFi Communications.
Refers to the strength of the radio signals from the WiFi networks that are available at your location.
Refers to the version of the 802 .11 protocol that is run by the network. The modes are a, b, or g, or these modes in combination.
Refers to the speed in megabits per second of the particular network.
Connect to the unsecured WiFi network with the strongest signal.
# dladm connect-wifi
Connect to an unsecured network by specifying its ESSID.
# dladm connect-wifi -e ESSID
The connect-wifi subcommand of dladm has several more options for connecting to a WiFi network. For complete details, refer to the dladm(1M) man page.
Do either of the following:
Obtain an IP address from a DHCP server.
# ipadm create-addr -T dhcp interface
If the WiFi network does not support DHCP, you receive the following message:
ipadm: interface: interface does not exist or cannot be managed using DHCP
Configure a static IP address:
Use this option if you have a dedicated IP address for the system.
# ipadm create-addr -a address interface
# dladm show-wifi LINK STATUS ESSID SEC STRENGTH MODE SPEED net0 connected ofc none very good g 36Mb
In this example, the output indicates that the system is now connected to the ofc network. The earlier scan-wifi output from Step 4 indicated that ofc has the strongest signal among the available networks. The dladm connect-wifi command automatically chooses the WiFi network with strongest signal, unless you directly specify a different network.
Do either of the following, depending on the network to which the system is connected:
If the access point offers free service, you can now run a browser or an application of your choice.
If the access point is in a commercial WiFi network that requires a fee, follow the instructions provided at the current location. Typically, you run a browser, supply a key, and give credit card information to the network provider.
Terminate the WiFi session but leave the system running.
# dladm disconnect-wifi
Terminate a particular WiFi session when more than one session is currently running.
# dladm disconnect-wifi link
where link represents the interface that is being used for the session.
Cleanly shut down the system while the WiFi session is running.
# shutdown -g0 -i5
You do not need to explicitly disconnect the WiFi session prior to turning off the system through the shutdown command.
Example 5-1 Connecting to a Specific WiFi Network
The following example combines the different steps you would take to connect your Oracle Solaris laptop to a wireless network. The example also shows how you can force the system to connect to a specific and preferred wireless network instead of allowing the OS to randomly select the wireless network. In the example assume that you have the static IP address 10.192.16.3/24 configured on your laptop. The example begins with determining the availability of a WiFi link.
# dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE net0 Ethernet up 1500 full ath0 net1 Ethernet up 1500 full e1000g0 # ipadm create-ip net0 IFNAME CLASS STATE ACTIVE OVER lo0 loopback ok yes -- net0 ip ok yes -- # dladm scan-wifi LINK ESSID BSSID/IBSSID SEC STRENGTH MODE SPEED net0 wifi-a 00:0e:38:49:01:d0 none weak g 54Mb net0 wifi-b 00:0e:38:49:02:f0 none very weak g 54Mb net0 ofc-net 00:0d:ed:a5:47:e0 wep very good g 54Mb net0 citinet 00:40:96:2a:56:b5 none good b 11Mb # dladm connect-wifi -e citinet # ipadm create-addr -a 10.192.16.3/24 net0 ipadm: net0/v4 # ipadm show-addr net0 ADDROBJ TYPE STATE ADDR net0/v4 static ok 10.192.16.3/24 # dladm show-wifi LINK STATUS ESSID SEC STRENGTH MODE SPEED net0 connected citinet none good g 11Mb
Run a browser or other application to commence your work over the WiFi network.
# firefox
The home page for the Firefox browser appears.
Terminate the session but leave the laptop running.
# dladm disconnect-wifi # dladm show-wifi LINK STATUS ESSID SEC STRENGTH MODE SPEED net0 disconnected -- -- -- -- --
The output of show-wifi verifies that you have disconnected the net0 link from the WiFi network.
This procedure explains how to monitor the status of a WiFi link through standard networking tools and change a selected link property through the linkprop subcommand.
For more information, see How to Use Your Assigned Administrative Rights in Oracle Solaris 11.1 Administration: Security Services.
Use the following syntax:
# dladm show-linkprop link
For example, you would use the following syntax to show the status of the connection established over the net0 wireless link:
# dladm show-linkprop net0 ... PROPERTY VALUE DEFAULT POSSIBLE channel 5 -- -- powermode off off off,fast,max radio ? on on,off speed 36 -- 1,2,5.5,6,9,11,12,18,24,36,48,54 ...
 | Caution - Oracle Solaris automatically chooses the optimal speed for the WiFi connection. Modifying the initial speed of the link might cause reduced performance or prevent the establishment of certain WiFi connections. |
You can modify the link speed to one of the possible values for speed that is listed in the show-linkprop output.
# dladm set-linkprop -p speed=value link
# netstat -I net0 -i 5 input net0 output input (Total) output packets errs packets errs colls packets errs packets errs colls 317 0 106 0 0 2905 0 571 0 0 14 0 0 0 0 20 0 0 0 0 7 0 0 0 0 16 0 1 0 0 5 0 0 0 0 9 0 0 0 0 304 0 10 0 0 631 0 316 0 0 338 0 9 0 0 722 0 381 0 0 294 0 7 0 0 670 0 371 0 0 306 0 5 0 0 649 0 338 0 0 289 0 5 0 0 597 0 301 0 0
Example 5-2 Setting the Speed of a Link
This example shows how to set the speed of a link after you have connected to a WiFi network
# dladm show-linkprop -p speed net0 PROPERTY VALUE DEFAULT POSSIBLE speed 24 -- 1,2,5,6,9,11,12,18,24,36,48,54 # dladm set-linkprop -p speed=36 net0 # dladm show-linkprop -p speed net0 PROPERTY VALUE DEFAULT POSSIBLE speed 36 -- 1,2,5,6,9,11,12,18,24,36,48,54
