6 Steps to Troubleshoot Kasa Smart Plug Wi-Fi Connection Issues

Check Whether Your Plug Has Received Power

Your plug needs to be turned on and ready to connect to a Wi-Fi network for the connection process to work. That is, if your Kasa Smart Plug hasn’t received power, the app can’t find the plug, let alone connect to your home Wi-Fi.

So the first thing to do if you’re having difficulties connecting your Smart Plug to Wi-Fi is to confirm that your device is plugged into a working outlet and has received power. More so, the Wi-Fi indicator light on your plug should be rapidly blinking to show it’s ready to connect to a Wi-Fi network. If it isn’t blinking rapidly, press and hold the Power button until it blinks rapidly (should take 5 seconds or so).

Now try to connect your device to Wi-Fi again to see if it works. Did it work? If yes, congratulations. But if not, continue to the next step.

Check Your Wi-Fi Band

The TP-LINK Kasa Smart Plug doesn’t support the 5GHz Wi-Fi network band. If your router is set to a 5GHz Wi-Fi network, the connection may fail. So, check what Wi-Fi band you’re trying to connect to and switch to the appropriate one—2.4GHz.

You can switch your Wi-Fi band through your phone’s Wi-Fi settings or your router. Check your router’s user manual for detailed instructions if needed.

Ensure Your Wi-Fi Network Signal Strength is Strong

As you probably know, weak Wi-Fi signal strength may cause connectivity issues. However, I’m not sure if there’s a way to check your Wi-Fi signal strength in the app during setup; so you can try to improve Wi-Fi signal strength by putting your router closer to your Smart Plug.

If you can’t move your router from its current position because of other devices connected to it, consider getting a Wi-Fi extender to boost signal strength.

Check Your Router’s Connection Limit

There’s a limit to how many devices you can connect to your router at the same time. Depending on the router you’re using, check to see if you’ve reached the limit. If so, disconnect some devices and try to connect your plug again.

Also, ensure your Wi-Fi password is correct. As you can see during the setup, you’ll need to input your Wi-Fi password at some point to authorize the connection. So be sure your password is correct.

Check for Updates

Is your Kasa app and the smart plug’s firmware up-to-date? You may also face difficulties getting your Kasa Smart Plug to connect to Wi-Fi if the app/firmware is outdated.

So, another way to resolve connectivity issues with your plug is to check for updates—and ensure you’re running the current version of the app and the plug’s firmware.

You can update your Kasa App via your app store. If you use an android device, go to the Google Play Store. And for iOS devices, go to the App Store—search for the app and tap the update button.

To update your Kasa Smart Plug firmware, follow these steps:

  • Open the TP-Link Kasa App on your phone. Next, tap the Menu icon (looks like three horizontal lines) at the top left of the screen.
  • Tap Settings. Then tap Firmware Update.
  • If your Kasa Smart Plug requires an update, it will be displayed on the screen with other devices. If there’s a new firmware version, click on your device (as you can see on the screen) to update it.

If you’re still unable to get your TP-Link Kasa Smart Plug to connect to Wi-Fi after this, see the next step.

Restore Factory Default Settings on Your Kasa Smart Plug

This should help you fix Wi-Fi connectivity issues and other issues you’re having with your Kasa Plug. Yes, restoring default settings usually helps resolve such issues. So go ahead and reset the plug and start the setup process again.

To reset your Kasa Smart Plug, press and hold the Power button for a few seconds (5 seconds or so) until the indicator light blinks slowly and then rapidly. The rapid flashing shows the device is reset and now in setup mode.

Now start the setup process all over again. If you’re not sure how to set up your Kasa Smart Plug with the Kasa Smart App, go here for a step-by-step guide, including Alexa and Google Assistant setup.

Related Questions

How do I change the Wi-Fi on my Kasa Smart plug?

Changing the Wi-Fi on your Kasa Smart Plug requires you to reset the plug, then set it up again with the new Wi-Fi. Note that there’s no way to do this via the app, so press the power button for a few seconds until the LED indicator blinks rapidly. This will reset the plug, so you can now connect it to a new Wi-Fi network.

Kasa smart plug keeps disconnecting; what do I do?

Check and set your router to broadcast the Wi-Fi network on the 2.4GHz band only. Note that the plug doesn’t support the 5GHz band, so if the router switches by itself to this band, your plug may lose connection.

More so, ensure your Kasa Smart Plug is not positioned too far from the router. It may not receive sufficient Wi-Fi signals if located too far from the Wi-Fi router. You can upgrade your router or get a Wi-Fi extender to boost Wi-Fi signal strength.

If the issue persists, reset the plug and set it up again. This should resolve the ‘disconnection’ issue.

Does Kasa Smart Plug work with Alexa?

Yes. Kasa Smart Plug works with Alexa and Google Home. So you can set up the device with these voice assistant systems for hands-free control.

Wrapping Up

So that’s how to troubleshoot Wi-Fi connectivity problems with your TP-LINK Kasa Smart Plug. As mentioned, you may experience connection issues with your plug due to several reasons—so make sure to try all the troubleshooting steps to see which one fixes the problem.
