Using the Troubleshooting Utility

The troubleshooting utility enables you to identify and resolve configuration and association problems with your client adapter. It is meant to be used only when the client adapter is in infrastructure mode because it assesses the connection between the adapter and an access point.

Follow the instructions in one of the subsections below to use the utility to diagnosis your client adapter’s operation, save a detailed report to a text file, or access online help.

Diagnosing Your Client Adapter’s Operation

Step 1 Perform one of the following to activate the troubleshooting utility:

•Open ADU; choose Troubleshooting from the Action drop-down menu.

•Open ADU; click the Diagnostics tab and Troubleshooting.

•Right-click the ASTU icon; choose Troubleshooting from the pop-up menu. The Troubleshooting Utility window appears (see Figure 10-1).
