When you are having trouble connecting to the internet, you can use the official Chrome Connectivity Diagnostics tool to troubleshoot and find the problem. Occasionally, the wireless routers, modems and dongles we use to connect to the internet malfunction. No matter how many times you try to reload a web page, it simply doesn't load! If you don't have a good diagnostic tool on hand, it can be quite difficult to find, isolate and fix the issue. In this article, you'll learn how to:
A useful application (browser extension) that will help you when you are having problems with your network is Google's Chrome Connectivity Diagnostics for the Google Chrome web browser and ChromeOS. This app lets you run network diagnostics right from within your Chrome browser. It uses the Google connectivity services and test for common problems like a slow network (network latency), blocked ports, and checks that the various ways you connect to the network are function correctly. The diagnostics tool checks HTTP and HTTPS for webpages, as well as TCP and UDP, used by other software programs to communicate over the internet. Note: There are a few extra connectivity tests that this app runs if you are using Chrome on a Google device that runs ChromeOS.
Once the app is successfully installed, click on the green Launch App button to open it. The Chrome App Launcher can also be used to open the app.
You can find the app and launch it in the Chrome app launcher once you have installed it, if you don't want to run it immediately.
The Chrome Connectivity Diagnostics app will automatically run through all of the standard networking diagnostics, including the WiFi strength test, as soon as you open it. You don't even need to select anything! This may take a little time, more if there are intermittent network problems.
If no problems with any of the network diagnostics tests were discovered, you will see the message: Your network connection appears to be operating correctly.
You can see a detailed report for each of the tests below this message. Click on any of the individual tests to see more details.
Click on the Show logs link to see the fully detailed technical logs. Your internet service provider may require such logs to help diagnose any problems on their end. Click on the Copy result logs link underneath the log details to copy the text, and past it into a plain .txt file in a text editor.
Some common error messages that you may see include:
The Chrome Connectivity Diagnostic tests also check for the following specific problems:
Not all of these problems are caused by your own network - some may be caused by your internet service provider, or further into the internet. If you are having trouble loading a page on a specific website, instead of using the Chrome Connectivity Diagnostics, check to see if the website is down first.
If you are using ChromeOS, you can test the strength of your wireless network using the Chrome Connectivity Diagnostics extension. Again, this test will be run automatically, as soon as you open the application. It will also test to see if your default gateway is reachable or not.
The standard solution for all local network issues is to reboot! Turn your modem and router off and back on again. Power cycling can fix a number of hardware issues. If this hasn't worked, check with your internet service provider using a mobile connection - they may be experiencing problems with their systems.
Once you have fixed any local network problems, rerun the network diagnostics and see if things have improved.
If the Chrome Connectivity Diagnostics tests reported everything was working fine, you may have a problem with Chrome itself. Check the following articles for solutions to some of the more common problems.
