How to turn off Wifi via ADB?

Question

Im automating a testing procedure for wifi calling and I was wondering is there a way to turn off/on wifi via adb?

I would either like to disable/enable wifi or kill wifi calling (com.movial.wificall) and restart it.

Is it possible to do this all via adb and shell commands?

so far I have found:

android.net.wifi.WifiManager
setWifiEnabled(true/false)

Im just not sure how to put it together

Answer 1

Using "svc" through ADB (rooted required):

Enable:

adb shell su -c 'svc wifi enable'

Disable:

adb shell su -c 'svc wifi disable'

Using Key Events through ADB:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell input keyevent 20 & adb shell input keyevent 23

The first line launch "wifi.WifiSettings" activity which open the WiFi Settings page. The second line simulate key presses.

I tested those two lines on a Droid X. But Key Events above probably need to edit in other devices because of different Settings layout.

I was searching for the same to turn bluetooth on/off, and I found this:

adb shell svc wifi enable|disable

Answer 3

Simple way to switch wifi on non-rooted devices is to use simple app:

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WifiManager wfm = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        try {
            wfm.setWifiEnabled(Boolean.parseBoolean(getIntent().getStringExtra("wifi")));
        } catch (Exception e) {
        }
        System.exit(0);
    }
}

AndroidManifest.xml:

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

ADB commands:

$ adb shell am start -n org.mytools.config/.MainActivity -e wifi true
$ adb shell am start -n org.mytools.config/.MainActivity -e wifi false

adb shell "svc wifi enable"

This worked & it makes action in background without opening related option !!

Answer 6

I tested this command:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell input keyevent 19 & adb shell input keyevent 19 & adb shell input keyevent 23

and only works on window's prompt, maybe because of some driver

about adb shell svc wifi enable|disable i guess that only work with root permission

Answer 7

use with quotes

ex: adb shell "svc wifi enable"

this will work :)

Answer 8

I can just do:

settings put global wifi_on 0
settings put global wifi_scan_always_enabled 0

Sometimes, if done during boot (i.e. to fix bootloop such as this), it doesn't apply well and you can proceed also enabling airplane mode first:

settings put global airplane_mode_on 1
settings put global wifi_on 0
settings put global wifi_scan_always_enabled 0

Other option is to force this with:

while true; do settings put global wifi_on 0; done

Tested in Android 7 on LG G5 (SE) with (unrooted) stock mod.
