Solution 1

Below command will give you the internet status and connectivity mode(cellular or Wi-Fi)

adb shell dumpsys connectivity

Solution 2

To know everything about Wifi status of the device:

adb shell dumpsys wifi

To just know whether it's enabled or not:

adb shell dumpsys wifi | grep "Wi-Fi is"

To know more detailed status:

adb shell dumpsys wifi | grep "mNetworkInfo"

If connected to a valid network, it shows "CONNECTED/CONNECTED". It also shows the name of the connected network.
If wifi has been enabled but it is yet to connect to a network, it shows "DISCONNECTED/SCANNING".
If wifi is disabled, it shows "DISCONNECTED/DISCONNECTED".

Solution 3

If you're trying to determine whether or not WiFi is turned on you can run adb shell settings get global wifi_on which returns 1 if it's on and 0 if it's off.

If you have multiple devices connected you can run adb -s [UDID_HERE] shell settings get global wifi_on to get the WiFi status of an individual phone. To find the UDID you can run adb devices.

Solution 4

This would only tell you if there is internet access but you can do:

adb shell ping www.google.com

Solution 5

adb shell dumpsys wifi | sed -n '1p'

is faster and more safely than

adb shell dumpsys wifi | grep "Wi-Fi is"

Because the output of 'dumpsys wifi' contains the system logs that may has been contaminated by other application

Im automating wifi off/on via adb.

I would either like to disable/enable wifi based on the test case

so far I have found good information here

However I want to test the connection before executing following 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
```
Above command disables wifi if enabled, enables wifi if disabled. I want to first test the connection and take action if required. I am wondering if there is a way to do using adb command. This can be achieved programatically but I want it to be done through adb for making it more reliable.

Also following command works only if device is rooted
```
adb shell "svc wifi enable" 
```
Also following command launches test on screen but provides no info via adb
```
adb shell am start -n com.android.settings/.wifi.WifiStatusTest
```

Android O onwards. adb shell dumpsys wifi | grep "curState" will give following 3 otputs dpending upon state 1. "InitialState" : if Wifi is off. 2. "DisconnectedState" if wifi is on but disconnected , 3. "ConnectedState": if device connected to network.

Will this work, if I use those commands in Java, using Process and Runtime for example?

adb shell dumpsys wifi | grep "mNetworkInfo" is not working with Android 11. do we have any alternatives?

The command line "dumpsys wifi" works for me. But be aware, in my case, I found on one android device the "Wi-Fi is enabled" is at the first line, while on another phone, such output is NOT at the first line, so I think grep "Wi-Fi is" is the better apporach.
