Sometimes the wireless router and dongle that we use to connect to the Internet, functions like a useless heap of plastic. No matter how hard you try to connect, the device just doesn’t respond to your request. Under such circumstances, if you do not have a good diagnostic tool at hand it becomes difficult to identify, isolate and rectify the problem.
Luckily, if you’re a Google Chrome user, there’s an easy way out! Chrome Connectivity Diagnostics might just be the app you would be looking for. The Chrome extension from Google is a fast and simple network testing and troubleshooting tool for Chrome and ChromeOS. People find it of little use to install when the full force of the internet is flowing freely. However, you can unleash its true potential when you experience connectivity issues.
Chrome Connectivity Diagnostics from Google
The tool tests a computer’s network connection for common issues, port blocking, and network latency by establishing connections to network and Internet services via UDP, TCP, HTTP and HTTPS.
Visit the Chrome App store and download the extension. Launch the app, the tests will automatically start running with a progress bar like the one appearing below.
When the test is complete, you are presented with the problem/s.
In my case, there were 2 issues noted,
- DNS Resolution taking too long
- Web Request to Google taking too long
For more detailed information, you can select the Gear icon in the upper-right corner, and click on “Show Passing Tests.”
This will show you different test results. Clicking on the individual tests will provide a brief description of the test and a link to the logs.
