How to Generate and Analyze a Detailed Wi-Fi History Report in Windows 11 Using the netsh wlanreport Command

Intermittent Wi-Fi disconnections, sudden signal degradations, and roaming failures on corporate laptops are notoriously difficult to diagnose in Windows 11. The consumer network settings tray only provides basic connection status, while digging through scattered Event Viewer logs (such as WLAN-AutoConfig and NDIS) requires hours of cross-referencing event IDs and hex error codes.

Fortunately, Windows 11 contains an automated, enterprise-grade diagnostic engine built directly into the Netsh utility: netsh wlan show wlanreport (commonly referred to as wlanreport). With a single command, Windows compiles a comprehensive, interactive HTML dashboard analyzing the last three days of wireless adapter sessions, connection drops, driver error codes, power state transitions, and router BSSID handoffs. This guide demonstrates how to generate and interpret the wireless report.

Generating the Wireless Network Report

Because gathering low-level NDIS driver events requires elevated permissions, execute the command from an administrative prompt:

1. Press Win + X and select Terminal (Admin).
2. Type the following command and press Enter:

   netsh wlan show wlanreport

3. Windows analyzes system logs, generates the visual HTML report, and outputs the destination file path:

   Report written to: C:\ProgramData\Microsoft\Windows\WlanReport\wlan-report-latest.html

Opening and Navigating the HTML Dashboard

To view the generated report in Microsoft Edge or your default browser, run:

start C:\ProgramData\Microsoft\Windows\WlanReport\wlan-report-latest.html

Interpreting Critical Report Sections

1. Wi-Fi Summary Timeline

At the top of the dashboard, Windows plots an interactive timeline of your Wi-Fi sessions over the past 72 hours:

• Green bars: Successful, stable connected sessions.
• Red circles with X: Sudden disconnection failures or packet drops.
• Yellow triangles: Warnings (e.g. limited connectivity, IP address renewal timeouts).
• Clicking any symbol immediately jumps to the exact timestamped event log below.

2. Disconnect Reasons and Diagnostic Codes

The report details the exact operational cause of every disconnection:

• The network is disconnected by the driver: Indicates physical Wi-Fi hardware crashes or outdated chipset firmware.
• The network is disconnected by the user: Normal intentional disconnects.
• Explicit disconnect from network: Access point de-authentication or roaming failure between mesh nodes.

3. Network Adapter and Power Management Information

Scroll down to inspect your wireless NIC hardware properties:

• Verifies installed Wi-Fi driver versions and date stamps.
• Highlights whether Modern Standby (S0 Low Power Idle) caused the wireless radio to enter sleep prematurely during active downloads.

WlanReport Diagnostic Indicators Reference Table

Report Indicator	Meaning	Recommended Action
Driver Error Code 0x00000002	Adapter reset failure	Update or reinstall OEM wireless chipset drivers
Excessive Roaming Events	Rapid switching between BSSIDs	Lower adapter Roaming Aggressiveness in Device Manager
DHCP Renewal Timeout	Failed to obtain IP address	Inspect router DHCP pool capacity and lease times
