Wifi

In this section you will learn how to get detailed information about available wifi networks, interfaces and connections:

For function reference and examples we assume, that we imported systeminformation as follows:

const si = require('systeminformation');

Wifi Networks

All functions in this section return a promise or can be called with a callback function (parameter cb in the function reference)

Function Result object Linux BSD Mac Win Sun Comments
si.wifiNetworks(cb) [{...}] X X X X X array of available wifi networks
[0].ssid X X X Wifi network SSID
[0].bssid X X X BSSID (mac)
[0].mode X mode
[0].channel X X X channel
[0].frequency X X X frequengy in MHz
[0].signalLevel X X X signal level in dB
[0].quality X X X quaility in %
[0].security X X X array e.g. WPA, WPA-2
[0].wpaFlags X X X array of WPA flags
[0].rsnFlags X array of RDN flags
Example
const si = require('systeminformation');
si.wifiNetworks().then(data => console.log(data));
[
  {
    ssid: 'INTERNAL-WIFI',
    bssid: 'ab:01:14:4f:d3:82',
    mode: '',
    channel: 44,
    frequency: 5220,
    signalLevel: -68,
    quality: 64,
    security: [ 'WPA', 'WPA2' ],
    wpaFlags: [ 'PSK/TKIP/TKIP', 'PSK/AES/TKIP' ],
    rsnFlags: []
  },
  {
    ssid: 'FREE Wifi',
    bssid: 'aa:14:e5:16:97:f3',
    mode: '',
    channel: 44,
    frequency: 5220,

Wifi Interfaces

All functions in this section return a promise or can be called with a callback function (parameter cb in the function reference)

Function Result object Linux BSD Mac Win Sun Comments
si.wifiInterfaces(cb) [{...}] X X X array of detected wifi interfaces
[0].id X X X Wifi ID
[0].iface X X X interface
[0].model X X X model
[0].vendor X X X vendor
[0].mac X X X interface MAC
Example
const si = require('systeminformation');
si.wifiInterfaces().then(data => console.log(data));
[
  {
    id: 'Wi-Fi',
    iface: 'en0',
    model: 'AirPort',
    vendor: '',
    mac: 'a0:b1:c2:d3:e4:f5'
  },
  ...

Wifi Connections

All functions in this section return a promise or can be called with a callback function (parameter cb in the function reference)

Function Result object Linux BSD Mac Win Sun Comments
si.wifiConnections(cb) [{...}] X X X array of active wifi connections
[0].id X X X Wifi ID
[0].iface X X X interface
[0].name X X X name
[0].model X X X model
[0].ssid X X X Wifi network SSID
