If you’re having connectivity problems with Wi-Fi connections in Windows Server 2008 or Vista, you can use the tracing feature of the new WLAN commands for Netsh, a powerful command line utility. Once a trace has been completed, a report is compiled at C:\windows\tracing\wireless and viewable in the Windows performance monitor.
Use this syntax from the Command Prompt:
netsh wlan set tracing mode={yes|no|persistent}
Persistent mode means tracing will remain active indefinitely and must be manually stopped using the No mode. In the Yes mode, tracing is automatically turned off after the system restarts.
