Command for Testing PC's Wifi Antenna
I have an HP laptop that cannot find any wifi networks. It can however connect to internet through ethernet. It doesn't appear to be anything simple such as airplane mode, but I was wondering is there a command prompt command I can enter to check if the wifi antenna is functional and what its strength is? Not talking about the router/modem signal strength.
Wi-Fi strength from Taskbar
For Windows 10 first check the Wi-Fi signal strength by using the Wi-Fi icon in the Taskbar. The icon for the Wi-Fi in the Taskbar is dynamic and adjusts itself according to the Wi-Fi signal strength with the more curvy lines, the greater the signal strength. Each line represents 25 percent Wi-Fi signal strength.
The in built 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
- 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.
- At the command prompt, type
netsh wlan show wlanreport.

To extract just signal strength as a percentage again from the elevated (administrator) command prompt type
netsh wlan show interfaces | ?{$_ -Match "Signal"}
