Chrome Connectivity Diagnostics tests your network connection

RECOMMENDED: Click here to fix Windows errors and optimize system performance

Sometimes the wireless router and dongle we use to connect to the Internet works like a useless pile of plastic bodies. No matter how hard you try to connect, the device will simply not respond to your request. In such circumstances, it becomes difficult to identify, isolate and solve the problem if you do not have a good diagnostic tool.

Fortunately, if you are a Chrome user, there is an easy way out! Chrome Connectivity Diagnostics could be exactly the application you are looking for. The Chrome extension is a fast and easy network testing and troubleshooting tool for Chrome and ChromeOS. People find it of little use to install it when the full power of the Internet flows freely. However, you can realize your true potential if you have connectivity problems.
