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

Answer 1

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

The adb shell svc wifi enable|disable solution only works with root permissions.

Answer 2

1. go to location android/android-sdk/platform-tools
2. shift+right click

3. open cmd here and type the following commands

   1. adb shell
   2. su
   3. svc wifi enable/disable

4. done!!!!!

Answer 3

This works as of android 7.1.1, non-rooted

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

This will launch the activity and then send the DPAD center keyevent. I added another DPAD center as an experiment to see if you can enable it in the same way.

The following method doesn't require root and should work anywhere (according to docs, even on Android Q+, if you keep targetSdkVersion = 28).

1. Make a blank app.

2. Create a ContentProvider:

   class ApiProvider : ContentProvider() {
   
       private val wifiManager: WifiManager? by lazy(LazyThreadSafetyMode.NONE) {
           requireContext().getSystemService(WIFI_SERVICE) as WifiManager?
       }
   
       private fun requireContext() = checkNotNull(context)
   
       private val matcher = UriMatcher(UriMatcher.NO_MATCH).apply {
           addURI("wifi", "enable", 0)
           addURI("wifi", "disable", 1)
       }
   
       override fun query(uri: Uri, projection: Array<out String>?, selection: String?, selectionArgs: Array<out String>?, sortOrder: String?): Cursor? {
           when (matcher.match(uri)) {
               0 -> {
                   enforceAdb()
                   withClearCallingIdentity {
                       wifiManager?.isWifiEnabled = true
                   }
               }
               1 -> {
                   enforceAdb()
                   withClearCallingIdentity {
                       wifiManager?.isWifiEnabled = false
                   }
               }
           }
           return null
       }
   
       private fun enforceAdb() {
           val callingUid = Binder.getCallingUid()
           if (callingUid != 2000 && callingUid != 0) {
               throw SecurityException("Only shell or root allowed.")
           }
       }
   
       private inline fun <T> withClearCallingIdentity(block: () -> T): T {
           val token = Binder.clearCallingIdentity()
           try {
               return block()
           } finally {
               Binder.restoreCallingIdentity(token)
           }
       }
   
       override fun onCreate(): Boolean = true
   
       override fun insert(uri: Uri, values: ContentValues?): Uri? = null
   
       override fun update(uri: Uri, values: ContentValues?, selection: String?, selectionArgs: Array<out String>?): Int = 0
   
       override fun delete(uri: Uri, selection: String?, selectionArgs: Array<out String>?): Int = 0
   
       override fun getType(uri: Uri): String? = null
   }
   

3. Declare it in AndroidManifest.xml along with necessary permission:

   <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
   
   <application>
   
       <provider
           android:name=".ApiProvider"
           android:authorities="wifi"
           android:exported="true" />
   </application>
   

4. Build the app and install it.

5. Call from ADB:

   adb shell content query --uri content://wifi/enable
   adb shell content query --uri content://wifi/disable
   

6. Make a batch script/shell function/shell alias with a short name that calls these commands.

Depending on your device you may need additional permissions.

Answer 5

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.

Answer 6

adb shell "svc wifi enable"

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