How to Generate a Windows Wi-Fi Error Report

Your Wi-Fi keeps dropping out randomly. You check the taskbar, and it says you are connected. A minute later, a webpage will not load. It is incredibly frustrating to troubleshoot a problem you cannot consistently see.

You do not have to guess what is going wrong.

Windows actually keeps a detailed, hidden logbook. It records every single Wi-Fi connection, every disconnection, and every error that happens on your computer. You just need to know how to ask for it.

We will show you the simple command to generate this hidden report. We will also explain how to read the basics so you can find out exactly why your internet keeps dropping.

What is the Wireless Network Report?

This report is a diagnostic file built directly into Windows. It looks back over the last three days of your computer’s activity to show you exactly what your Wi-Fi adapter has been doing.

It records the exact times you connected to a network and when you disconnected. Most importantly, it logs the specific reason why a connection dropped out or failed.

Having this information takes the guesswork out of fixing your internet. It shows you a clear timeline of your computer’s network history.

How to Generate Your Wi-Fi Report

You need to use the Command Prompt to create this file. You must run it with administrator permissions so Windows can gather all the necessary system data.

Here is exactly how to do it:

1. Click your Start Menu and type cmd.
2. Right-click on Command Prompt in the search results and select Run as administrator.
3. A black text window will open. Type this exact command: “netsh wlan show wlanreport“
4. Press Enter.

Windows will take a few seconds to compile the data. When it finishes, it will display a message confirming the report was written. It will also show you the exact folder location where it saved the file.

How to Find and Read the Report

The file is saved deep in your Windows folders. The easiest way to open it is to copy the location and paste it directly into your web browser.

1. In the black Command Prompt window, highlight the file path it just gave you. It usually looks like this: C:\ProgramData\Microsoft\Windows\WlanReport\wlan-report-latest.html
2. Open your web browser (like Chrome or Edge).
3. Paste that path into the address bar at the top and press Enter.

The report will open as a webpage. It contains a massive amount of technical jargon. Ignore the text for now.

Look at the colourful chart right at the top. This is a visual timeline of your Wi-Fi over the last three days.

Hover your mouse over the different coloured lines and circles. Green means the connection was fine. You want to look for the red circles with an ‘X’. These represent failures and errors. Clicking on a red circle will jump you straight to the exact error message that caused the dropout.

The Two Most Common Wi-Fi Errors

When you click on those red circles, you will see a reason for the failure. Do not worry if it sounds highly technical. Most dropouts come down to two main problems.

Driver Failures

Sometimes the report says the driver stopped responding or crashed. This means the software controlling the Wi-Fi card inside your computer is failing.

If you see this, the fix is usually software-based. You need to visit your computer manufacturer’s website and download the latest Wi-Fi driver update for your specific machine.

Network Failures

The report might say the network disconnected the computer or the signal was lost. This tells you your PC is perfectly fine.

The issue is external. It is likely your physical router, wireless interference from other devices, or an outage with your internet provider. You should stop changing settings on your computer and focus on restarting your modem or checking your router instead.

This report contains a lot of heavy technical jargon. It is easy to feel overwhelmed by the long list of network codes and system errors.
