Getting Data Out of the Windows ‘netsh wlan show interfaces’ Command

I recently read a very nice article by Matt Frederick about using a Windows command prompt utility to gain information about what your Windows wireless adapter is up to while connected to a Wi-Fi network ( https://finesine.com/2016/09/17/using-netsh-wlan-show-interfaces-to-monitor-associationroaming/)

In  Matt’s article, he described how he wrapped the ‘netsh’ command into a nice little batch file to run the command regularly, allowing information to be presented in a more dynamic fashion.

I was so impressed with the information provided by the utility, that I decided I’d  try to get the information it provides into a more usable format. In short, I hacked together a Windows Powersell script that runs the ‘netsh’ CLI utility regularly and parses the output data into a CSV format.

By piping the output into a file, you can get a nice CSV file that can be opened in Excel to look at the raw data over a period of time. It’s great for looking at the adapter signal level and BSSID information …
