Chrome Connectivity Diagnostics tests your Network Connection

Sometimes the wireless router and dongle that we use to connect to the Internet, functions like a useless heap of plastic body. 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 Chrome user, there’s an easy way out! Chrome Connectivity Diagnostics might just be the app you would be looking for. The Chrome extension 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 it’s true potential when you experience connectivity issues.
