W-Fi connections setup and/or maintenance may be quite tricky; it could be hard to determine what is the exact reason of connection failure. In case of Windows Server 2008 or Vista, you can use the powerful command-line tool, netsh, to provide you with a lot of relate information.
netsh can be used in so called tracing mode, in which case it creates a detailed report on connection whereabouts. To manage tracing, use the following command line:
netsh wlan set tracing mode={yes|no|persistent}
Once the tracing is complete, the report is placed in %WINDOWSROOT%\tracing\wireless where it can be viewed with Windows performance monitor.
A note of warning: persistent tracing means the tracing must be stopped manually using the 'no' parameter.
If 'yes' parameter was used, tracing is automatically turned off after a system reboot.
