Wifi

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

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));
