How to enable Vista wireless tracing for troubleshooting

To troubleshoot and debug issues that occur before a user logs on to the computer, you may want to enable tracing for a WLAN by using Performance Monitor or by using the netsh command-line tool.

To enable persistent tracing for a WLAN in Windows Vista, follow these steps:

Click Start, and then type cmd in the Start Search box.

Right-click cmd in the Programs list, and then click Run as administrator.

If you are prompted to confirm that you want to continue, click Continue.

Type the following line at the command prompt, and then press ENTER:

netsh wlan set tra persistent

Tracing starts immediately and is persistent. When you restart the computer, tracing starts shortly after the WLAN AutoConfig service starts. Existing trace log files are overwritten.

Note To stop tracing after you enable it, use the following command:

Netsh wlan set tra no
