Enabling tracing for wireless LAN in Vista

This article explains how to enable tracing for wireless local area networks (WLANs) when starting a computer running Windows Vista. To enable tracing when you start your computer, you must enable permanent tracing from the command line.
You can enable tracing for Wi-Fi by using Performance Monitor or by using the netsh command-line tool. By default, the tracking mode in Windows Vista is non-permanent. That is, after tracing is enabled, tracing remains active until you manually stop tracing or restart your computer.
In some cases, you may have to enable tracing for your Wi-Fi when you start your computer. For example, you might want to do this to resolve and troubleshoot problems that users have before logging in to the computer. To do this, use the netsh command-line tool to enable tracing and set the mode to the persistent parameter. Permanent tracking means that tracking will remain active after tracing is enabled, even after restarting the computer.
To enable permanent tracking for Wi-Fi in Windows Vista, follow these steps: 1. Click Start, and then type cmd in the Start Search box.
2. In the Programs list, right-click cmd, and then click Run with administrator account.
If you are prompted to confirm if you want to continue, click Continue.
3. Type the following line at the command prompt, and then press ENTER:
netsh wlan set tra persistent
The trace will start immediately and be permanently tracked. When you restart your computer, tracing starts immediately after the WLAN AutoConfig service starts. Existing trace log files will be overwritten.
Note: To stop tracing after tracing is enabled, use the following command:
Netsh wlan set tra no
