  wifi.scan() // scan once
})

wifi.on('update', function () {
  var cur = wifi.currentNetwork
  console.log('Current network:', cur && cur.ssid)
  console.log('Available networks:')

  wifi.networks.forEach(function (n) {
    console.log(n.ssid + ', ' + n.frequency + ', ' + n.signal)
  })
})

API

var wifi = wpa(interfaceName)
