Get Internet connection state

Question

Hi all,&nbsp;Is it possible to get Internet connection state ? I would like to find out if my connected device has Internet connection or not. Googling I found only approach for programmers - http://stackoverflow.com/questions/1560788/how-to-check-internet-access-on-android-inetaddress-never-timeouts.&nbsp;For TestComplete I found only check for WiFi state - https://support.smartbear.com/viewarticle/73449/ but Mobile.Device.Connections doesn't have property InternetConnection&nbsp;Marek&nbsp;

Hi Marek,
&nbsp;
Your device appears to have a version of ping that can only run as a standard user.&nbsp;However, adb shell and TestComplete's ShellExecute run commands as root by default, hence the error.&nbsp;This link suggests changing file permissions for ping to make it compatible with adb shell&nbsp;-- if that's OK&nbsp;in your&nbsp;case. I couldn't&nbsp;find a general way to run adb shell&nbsp;commands as a standard/non-root user though.
&nbsp;
Other possible solutions would be to use external apps. For example:

Write a helper&nbsp;Android app (or find an existing one) that would check Internet connectivity. See these links&nbsp;for code examples.
If you have&nbsp;an instrumented application with a WebView, you can try navigating the WebView to some site, and check if the page loads successfully.

Hope this helps.

Hi Marek,

Assuming you're using Android devices, you can try pinging some well-known host, for example, google.com.
// JScript
var strResult = Mobile.Device("emulator-5554").ShellExecute("ping google.com");
If the device has Internet connection, the command output will be like this:
PING google.com (109.195.185.102) 56(84) bytes of data.
Otherwise it will be something like:
ping: unknown host google.com

It looks like your ISP (Slovak Telekom, according to whois 213.81.185.160) uses DNS hijacking to convert non-resolving domains into requests for your.isp.com/search?q=nosuchdomain. You might want to check with your ISP to see&nbsp;if it's possible to opt out of this.
&nbsp;
I'm not sure why the device shows "Webpage not available" but adb ping succeeds. Maybe when the device is connected to the computer, it uses the computer's Internet&nbsp;via USB. You can disable USB Internet in the device settings &gt;&nbsp;Wireless &amp; Networks (or similar).
&nbsp;
Also, you can try pinging an IP instead, e.g. 8.8.8.8.

Hi Helen. Thanks for your advice, but I don't know why I get:

when I used following: 'adb shell ping www.google.a'

What do you get if you:

navigate to www.google.a in a browser on your device?
run "ping www.google.a" from the command prompt on your computer?
