Applies To: Windows 7, Windows Server 2008 R2

This example demonstrates the phases through which NDF diagnostics progresses in a diagnostic session for a failed attempt to connect to a wireless network. Upon completion, the example demonstrates how a user can review the resulting Troubleshooting Report to obtain additional details about the diagnostic session.

In this scenario, a Windows® 7 user is attempting to connect to a wireless network. Windows® 7 is unable to connect to the specified wireless network, and displays a message indicating the connection attempt was unsuccessful. An option is provided to launch diagnostics by clicking Troubleshoot problems. This is shown in the following figure.

Unable to connect to the intended network

 

The user clicks Troubleshoot problems, and Windows Network Diagnostics starts. This is shown in the following figure.

Starting network diagnostics

 

The status indicates that it is investigating for problems in connection management. This is shown in the following figure.

Looking for problems in connection management

 

Status transitions to indicate that diagnostics is looking for network adapter problems. This is shown in the following figure.

Looking for problems in network adapter

 

The diagnostics status is updated to inform you that it is collecting configuration details. In this phase, NDF is collecting information about the system that will be stored with the logs, in case support is needed. This is shown in the following figure.

Collecting configuration details

Because NDF detected a root cause for which a repair could be performed automatically, the repair is attempted without further user interaction.  If the repair had required user consent or administrative privileges, the user would have been prompted before proceeding.

Status indicates that the wireless adapter is reset as part of the corrective steps. This is shown in the following figure.

Reset your wireless network adapter

 

NDF checks to make sure that the problem has been resolved by the fix. This is shown in the following figure.

noteNote
If not, diagnostics would restart to look for new issues uncovered by fixing the first one. For example, resetting the adapter lets you see wireless networks, but now you don’t have a profile for any network that is visible.

Detecting additional problems

 

Diagnostics does not detect any additional problems. The diagnostic results are collected as part of the NDF reporting feature. This is shown in the following figure.

Collecting results

 

Diagnostic status indicates troubleshooting has completed, and that a problem with the wireless adapter or access point was found and subsequently fixed. No additional problems were present – NDF confirms that the problem was fixed and that no new problems have appeared. This is shown in the following figure.

Problems with wireless adapter - Fixed

 

  • The user launched diagnostics in the context of a failed attempt to connect to a wireless network.

  • Diagnostics determined that a problem with the wireless adapter existed and automatically fixed the problem.

  • The summary of the diagnostic session tells the user that the problem is fixed. Diagnostics presented options that the user could select to view the diagnostic details, explore additional options, or end the diagnostic session.

Conclusion: Diagnostics successfully identified and corrected the wireless connectivity problem. No additional user action is required.

In this scenario, a user, support professional, or network admin wants to view the details of the diagnostic session to better understand the cause of the problem. The process to access and view the report occurs in the following phases.

Click Start, in Search programs and files, type Troubleshooting history, and then in the results, under Control Panel, click Troubleshooting History. This is shown in the following figure.

Accessing Troubleshooting History

 

Troubleshooting History opens. Click the Troubleshooting Report that corresponds to the diagnostic session to investigate. The Windows Network Diagnostics DetailsTroubleshooting report opens. This is shown in the following figure.

Selecting the pertinent diagnostic session history

 

In Issues found, diagnostics indicates there was a problem with the wireless adapter that has been fixed. Scroll down to Detection details to view additional details. This is shown in the following two figures.
