How to Monitor a WiFi Link
The following procedure describes how to monitor the status of a WiFi link through standard networking tools and also how to change a selected link property.
Before You Begin
Ensure that your role has the appropriate rights profile to perform this procedure. See Using Rights Profiles to Perform Network Configuration.
- Connect to a WiFi network, as described in How to Connect to a WiFi Network.
- View the properties of the system's datalinks.
$ dladm show-linkprop link
- Set a fixed speed for the link.
Caution - Oracle Solaris automatically selects the optimal speed for a WiFi connection. Modifying the initial speed of the link might diminish performance or prevent the establishment of certain WiFi connections.
You can modify the link speed to one of the possible values that are listed in the output of the show-linkprop subcommand, as shown in the following example:
$ dladm set-linkprop -p speed=value link
- Check the packet flow over the link.
$ netstat -I net1 -i 5 input net1 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
The following example shows how to set the speed of a link after you have connected to a WiFi network.
$ dladm show-linkprop -p speed net1 LINK PROPERTY PERM VALUE EFFECTIVE DEFAULT POSSIBLE net1 speed r- 25 0 0 1,2,5,6,9,11,12,18,24,36,48,54 $ dladm set-linkprop -p speed=36 net1 $ dladm show-linkprop -p speed net1 LINK PROPERTY PERM VALUE EFFECTIVE DEFAULT POSSIBLE net1 speed r- 36 0 0 1,2,5,6,9,11,12,18,24,36,48,54
