How To Diagnose Wi-Fi Drop Problem in Windows 10 PC.

Wlan Report.

A Wi-Fi connection that constantly drops can be infuriating. One way to diagnose the problem is to run Windows’ built-in Wi-Fi reporting tool. While some of the information in the report is highly technical, anyone can use it to glean basic information, as well as see which wireless networks your computer has been connecting to. 

To access the report, open Command Prompt with administrator privileges by clicking Start, typing CMD, then right-clicking the Command Prompt result and selecting ‘Run as administrator’ (if a User Account Control window appears, select Yes).

Once the report is complete, you’ll see ‘Report written to’, followed by the report file location. Copy this file path starting with 'C:\' but highlighting it with your mouse then pressing Ctrl+C.

The report will now appear with a chart at the top showing Wi-Fi activity over the past couple of days. Each green section of the chart indicates a connection. Hover over one of these and you’ll see the connect and disconnect times, along with the reason for the loss of connection.

List of useful information to analyze the Wi-Fi network:

WLAN Report shows you the Wi-Fi summary chart.
The red circle with a cross mark indicates some error. Click on any circle in the chart to get detailed information.

General System Info contains details about your PC like your computer name, system manufacturer, system product name, BIOS date, BIOS version, OS build, Machine ID.  

User Info contains information about the person who is currently signed in to the PC. The information it contains is a username, user domain, and user DNS domain.

Hover over the C (connect) and D (disconnect) icons at the top and you’ll see which network your PC was connected to at the time.

If you see a lot of sessions of short durations, it could be due to your computer constantly switching between your 2.4GHz and 5GHz network. You can check my post on how to split these networks and resolve the problem.
