How to Diagnose Wi-Fi Connection Issues on a Chromebook

Flaky Wi-Fi on your Chromebook? ChromeOS has a built-in Diagnostics app that tests your connection step by step, so you don’t have to guess where the problem is.

How to Run a Network Diagnostic

1. Click the launcher and search for Diagnostics, then open the app.
2. Click the Connectivity tab.
3. Select your Wi-Fi network and click Run test.
4. ChromeOS checks your Wi-Fi hardware, the connection to your router, and the connection from your router to the internet, showing a pass or fail for each step.

Quick Tips

• If the test fails at the router step, try restarting your router before anything else.
• You can also reach Diagnostics from Settings > About ChromeOS > Diagnostics.

This built-in tool replaced the old chrome://diagnostics page and now covers Wi-Fi, Bluetooth, and even battery and CPU checks in one place.
