How to Fix Kasa Smart Plug that’s Not Connecting

You should try the following solutions if you encounter connectivity problems with your TP-Link Kasa smart plug.

Confirm the Plug Receives Power

The first step is to verify that your smart plug is correctly plugged into a functioning power outlet and receives power. Without power, your Kasa Smart Plug will not function or be detected on your home Wi-Fi.

Another thing to check is if the Wi-Fi indicator light on your plug flashing rapidly. Hold the Power button until it blinks rapidly if the light is not flashing. Usually, it takes around ten seconds.

Check the WiFi Settings

Ensure your router has an active internet connection when you set up the smart plug. Connect to other devices like laptops, phones, or computers to access the internet strength.

If your Wi-Fi network has slow or average speeds, you need to do the following:

  • Restart your router by unplugging it from the power source. Reconnect it to the power source after waiting two minutes.
  • The next step is ensuring you enter the right network details when connecting the plug to your Wi-Fi network. Also, make no common mistake of adding extra spaces before or after the password when connecting smart devices to your network.


Note: TP-Link advises its users not to use a password with a length of fewer than 64 characters and without special characters such as @, #, /,, *,  ‘.


  • Go to the router admin portal and confirm if the “MAC address filtering” option is turned off. Once you activate this option, the router’s ability to link up with fresh devices will be inhibited.
  • As indicated earlier, Kasa Smart Plug is incompatible with the 5GHz Wi-Fi network frequency. So, switch to the 2.4GHz frequency.
  • It’s essential to check the Wi-Fi network security options. If you use “wpa2/wpa3-personal” Wi-Fi encryption for smart device connections, there’s a chance you’ll experience internet connection issues. I advise you to change to “WPA+AES.”
  • After you finish making changes to your router, please power cycle it to apply them. Then try to reconnect your smart plug.
