Windows Wifi troubleshooting tools

Have you ever tried connecting your laptop to a Wifi network and for one reason or another it failed?  It can be extremely frustrating, even to a seasoned vet who knows their way around Windows.  The big problem is that you get virtually no information from the connection failure.  No logs, no error codes, nothing.

There is a reporting tool that is built into windows 8 and newer that will compile a very detailed report showing each connection attempt, its status and a ton of other stuff.  Here’s how to run the report and where it gets put:

 

  • Open a command prompt as administrator
  • Run the following command
    • netsh wlan show wlanreport
  • Note the path where the html file is generated.  It should be C:\ProgramData\Microsoft\Windows\WlanReport\wlan-report-latest.html
  • Open your favorite web browser and point it to that file.  voila!

 

Here’s a snippet of what some of the report looks like:

There is a LOT more information below this including extremely detailed information about all the network adapters on the system, the system itself and some script output.  If you click on the items in the session list above, it will bring you to a detailed log of that session and why it was able to or not able to connect.

 

Suffice it to say this is an invaluable tool to review logs and information all in one place.
