The wireless network report is one of the more useful tools in Windows 10 that can help you diagnose Wi-Fi connection problems.

To create the wireless network report

1. In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator > Yes.
2. At the command prompt, type netsh wlan show wlanreport.
   
   This will generate a wireless network report that’s saved as an HTML file, which you can open in your favorite web browser.
