Diagnose Wi-Fi Problems with the Windows WLAN Report in Windows 10/11

Diagnose Wi-Fi Problems with the Windows WLAN Report in Windows 10/11​

Difficulty: Intermediate | Time Required: 10 minutes
Wi-Fi problems can be frustrating because the symptoms often look the same: pages stop loading, video calls freeze, downloads stall, or Windows says it is connected but there is no internet access. The cause, however, might be anything from a weak signal to a bad driver, router issue, DHCP problem, authentication failure, or random disconnect.
Windows 10 and Windows 11 include a built-in diagnostic tool called the WLAN Report. It creates an HTML report showing recent Wi-Fi sessions, errors, disconnect reasons, adapter details, IP configuration, and related network command output. It does not fix the problem automatically, but it gives you a much clearer starting point before you reset settings, replace hardware, or ask for help on the forum.

Prerequisites​

Before you begin, make sure you have:

1. A Windows 10 or Windows 11 PC with a Wi-Fi adapter.
2. Administrator access to the computer.
3. A recent Wi-Fi issue to investigate. The report is most useful when the problem happened recently.
4. A web browser, such as Microsoft Edge, Chrome, or Firefox, to open the report.
5. Optional but recommended: the approximate time the issue occurred.

Tip: If your Wi-Fi problem is intermittent, write down the time whenever it drops. Matching the time of the failure to the report makes troubleshooting much easier.

Step 1: Reproduce or note the Wi-Fi problem​

1. If the issue is happening right now, leave the system as-is for a moment.
2. Note what happened:
   • Did Wi-Fi disconnect completely?
   • Did it stay connected but lose internet?
   • Did it fail to connect to a specific network?
   • Did the problem happen after sleep, restart, or roaming between access points?
3. Write down the approximate time.

This matters because the WLAN Report organizes events by connection sessions. Knowing when the failure occurred helps you jump to the right section instead of guessing.

Step 2: Open Command Prompt as administrator​

1. Press Start or click the Search box on the taskbar.
2. Type Command Prompt.
3. Right-click Command Prompt.
4. Select Run as administrator.
5. If User Account Control appears, choose Yes.

You can also use Windows Terminal or PowerShell as administrator, but Command Prompt is the most straightforward option for this tutorial.

Note: Running as administrator is recommended because the report collects system-level networking details.

Step 3: Generate the WLAN Report​

1. In the elevated Command Prompt window, type:
   netsh wlan show wlanreport
2. Press Enter.
3. Wait a few seconds while Windows generates the report.
4. When finished, Command Prompt displays the location of the HTML report.

The report is usually saved in this folder:
C:\ProgramData\Microsoft\Windows\WlanReport\
The file you normally want is:
wlan-report-latest.html

Tip: ProgramData is a hidden folder by default. If you browse to it in File Explorer and do not see it, click the address bar and type the full path manually.

Step 4: Open the report​

You have two easy options.

Option A: Open from the command output​

1. In Command Prompt, look for the report path shown after the command finishes.
2. Select and copy the path if needed.
3. Paste it into your browser’s address bar.
4. Press Enter.

Option B: Open from File Explorer​

1. Press Windows key + R.
2. Type:
   C:\ProgramData\Microsoft\Windows\WlanReport\
3. Press Enter.
4. Double-click wlan-report-latest.html.

The report opens as a local webpage. You do not need an internet connection to view it.

Step 5: Start with the Wi-Fi Summary Chart​

At the top of the report, look for the Wi-Fi Summary Chart. This is one of the most useful sections because it gives a visual timeline of recent wireless sessions.

1. Look for red circles or warning indicators.
2. Match the problem time you wrote down earlier to the chart.
3. Click the relevant session or event to jump to the details.

A red error marker usually means Windows recorded a connection failure, disconnect, authentication issue, driver problem, or another event worth investigating.

Tip: Do not panic if you see a few warnings. Occasional Wi-Fi events can be normal, especially when moving between networks or waking from sleep. Focus on repeated errors or events that line up with your actual problem.

Step 6: Review the session details​

In the Wireless Sessions section, inspect the session that matches your issue.
Look for these fields:

1. Interface name — Confirms which Wi-Fi adapter was used.
2. Connection mode — Shows whether Windows connected automatically or manually.
3. Profile — Shows the saved Wi-Fi profile used for the connection.
4. SSID — Shows the wireless network name.
5. Session duration — Useful for random disconnects.
6. Disconnection reason — One of the most important fields.
7. Events — Shows the sequence of actions and failures.

Common patterns include:

• Very short sessions may suggest authentication, roaming, driver, or signal problems.
• Repeated disconnects from the same SSID may point to router, access point, or driver instability.
• Failures immediately after waking from sleep can suggest power management or driver issues.
• Authentication failures may mean an incorrect password, expired enterprise credentials, or security mismatch.
• DHCP or DNS-related symptoms may show up later in the script output.

Step 7: Check the Network Adapters section​

Scroll to Network adapters and find your wireless adapter. This section can reveal whether Windows sees a hardware or driver-level issue.
Check the following:

1. Device name — Confirms the Wi-Fi adapter model.
2. Current driver version — Useful when comparing against the PC maker’s support site.
3. Driver date — Very old drivers may be a clue.
4. Problem number — If listed, Windows detected a device problem.

Warning: Avoid installing random driver update utilities. For Wi-Fi drivers, use Windows Update, your PC manufacturer’s support page, or the adapter manufacturer’s official package.

Step 8: Review IPConfig and Netsh output​

The report includes command output such as IPConfig /all and NetSh WLAN Show All. These sections are excellent for spotting configuration issues.
In IPConfig /all, check:

1. Whether the Wi-Fi adapter has an IPv4 address.
2. Whether the address starts with 169.254. That often means Windows did not receive a valid DHCP address.
3. Whether a default gateway is listed.
4. Whether DNS servers are listed.
5. Whether DHCP is enabled.

In NetSh WLAN Show All, check:

1. Supported radio types.
2. Wi-Fi profiles saved on the PC.
3. Visible wireless networks at the time the report was generated.
4. Signal and adapter capability information where available.

If your PC connects to Wi-Fi but cannot browse, IP address, gateway, and DNS information are especially important.

Step 9: Decide what to try next​

Use the report to choose a targeted fix instead of guessing.
Try these based on what you find:

1. Driver or adapter errors: Update the Wi-Fi driver from Windows Update or the PC manufacturer.
2. Authentication failures: Forget the Wi-Fi network, then reconnect and re-enter the password.
3. DHCP problems: Restart the router, then run ipconfig /release and ipconfig /renew.
4. DNS problems: Test another DNS server or reset the network stack.
5. Weak or inconsistent signal: Move closer to the router or test the 2.4 GHz and 5 GHz bands separately.
6. Problems after sleep: Check adapter power management settings and update the driver.
7. Only one network fails: Focus on that router, access point, password, or security mode.
8. All networks fail: Focus on the Windows adapter, driver, VPN software, firewall, or security suite.

Step 10: Share safely on WindowsForum.com​

The WLAN Report can contain useful diagnostic details, but it may also include information you should not post publicly.
Before sharing screenshots or text, consider redacting:

1. Your computer name.
2. User name or domain name.
3. SSIDs you do not want public.
4. MAC addresses.
5. Public IP addresses.
6. Certificate or organization details.
7. Internal network names.

The report should not display saved Wi-Fi passwords in plain text, but you should still review anything before posting it.

Tip: When asking for help, include your Windows version, Wi-Fi adapter model, driver version, router model if known, and the exact disconnection reason shown in the report.

Conclusion​

The Windows WLAN Report is one of the fastest ways to move from “my Wi-Fi keeps dropping” to a useful diagnosis. In about 10 minutes, you can generate a readable HTML report, identify failed sessions, check disconnect reasons, review adapter driver details, and collect enough information to choose the next troubleshooting step.
It is especially helpful for intermittent issues because it gives you a timeline of recent Wi-Fi activity rather than relying only on memory. Whether you are fixing your own PC or asking the WindowsForum.com community for help, the WLAN Report gives everyone better evidence to work with.
Key Takeaways:

• The WLAN Report is built into Windows 10 and Windows 11.
• Use netsh wlan show wlanreport from an elevated Command Prompt to generate it.
• The report opens in a browser as an HTML file.
• The Wi-Fi Summary Chart and Wireless Sessions sections are the best places to start.
• Driver details, disconnect reasons, DHCP status, DNS settings, and adapter errors can help narrow the cause.
