Create and analyze a Wi-Fi report on Windows

If you’re having a problem with your Wi-Fi connection in Windows, it can sometimes be difficult to diagnose the cause without detailed information. Fortunately, Windows has a Wi-Fi report that you can use to understand most connectivity issues.

So what is the WiFi report and how do you generate and analyze it? Here’s what you need to know.

What is a Windows Wi-Fi Report?

The Wi-Fi or Wlan report is an HTML document that provides detailed information about Wi-Fi events on your Windows computer. This includes the networks you connected to, the duration of each session, and any errors you encountered. Also included in the WLAN report are the network adapters on your machine.

The report provides a historical overview of your Wi-Fi sessions over three days, and allows you to drill down into each session to find out what caused the issues you’re experiencing.

Before generating the WiFi report, see our guides on how to fix Windows 10 cannot detect WiFi and how to fix WiFi issues on Windows 11.

Analyzing the Windows Wi-Fi Report

The first thing you see at the top of the Wlan report is the Wi-Fi summary table.

You’ll see green bars in the chart, and they represent a session and its length (they’re ordered from oldest session to newest). When you hover over these green sections, you’ll get a session summary in the lower-left corner of the Wi-Fi summary table.

In the Wi-Fi summary table, you will also see circular icons in different colors with letters in them. These represent Wi-Fi events that occurred during a particular session. When you click on these icons, you will be taken to the part of the report that contains more information about the event.

When diagnosing problems during a session, look for red circular icons with an “X” in them, as that will indicate an error.

At the bottom right of the Wi-Fi summary table, you will find a legend that tells you the meaning of each icon.

Below the Wi-Fi overview table are a number of sections with more information about this. Let’s briefly discuss the sections you’re likely to look at to get the information you need — some other sections, such as: Report information, General System Informationand user informationare quite easy to understand:

  • Network adapters: This section contains information about both your physical and virtual wireless network adapters. This also includes any hidden adapters on your PC.
  • Overview: This section contains brief information about the Wi-Fi sessions you have started on your computer. You can see the successful and failed connections, the reasons for the disconnection and the duration of each session.
  • Wireless sessions: This is where the action takes place, because here you will find comprehensive details of each session. This includes the adapter you used, how you connected to the adapter (manually or automatically), the name of the Wi-Fi connection you used, and how long the session lasted. You can also see the events of each session, including the time they occurred and the associated message – click [+] on the left side of each post to see full details.
