Kasa Smart Plug Keeps Losing Wi-Fi Connection [Quick Fix]

ByNelson Morgan Last Updated on: Troubleshooting

Is your Kasa Smart Plug frequently disconnecting from Wi-Fi? You’re not alone!

In this post, I’ll explain why this might be happening and how to resolve the problem. Let’s get right into it.

Kasa Smart Plug

If your Kasa Smart Plug keeps losing Wi-Fi connection, here are some reasons behind this:

  • Your router is switching Wi-Fi bands by itself.
  • Your Wi-Fi signal strength is low.
  • You’re using an outdated version of the Kasa app.
  • Your Kasa Smart Plug’s firmware requires an update.

Now let’s head over to the troubleshooting steps.

Tips to Fix ‘Kasa Smart Plug Keeps Losing Wi-Fi Connection’ Issue

Reboot Your Router

If your TP-Link Kasa Smart Plug keeps losing Wi-Fi connection, the issue might come from your Wi-Fi network. To resolve this issue, start your troubleshooting by rebooting the router. This will refresh your Wi-Fi network and fix some errors obstructing the connection.

You can reboot your router by unplugging it from the power outlet and plugging it back in.

Next, unplug the Smart Plug from the power outlet and plug it back in.

If this doesn’t help, continue to the next step.

Check that Your Router is Not Changing Wi-Fi Bands Automatically

Most modern routers have dual-bands (2.4GHz and 5GHz). By default, the router switches bands by itself, depending on the one with the strongest Wi-Fi signal strength.

However, the TP-Link Kasa Smart Plug only supports the 2.4GHz Wi-Fi band. So, if your router switches to the 5GHz band, your plug will lose connection—since it doesn’t work with the 5GHz network.

If your Kasa Smart Plug is losing Wi-Fi connection frequently, check whether your router is changing Wi-Fi bands automatically. If so, set it to run on the 2.4GHz band only.

The procedure to change Wi-Fi bands depends on the router you are using. If you’re not sure how to do this, refer to your router’s user manual for guidelines.

If this checks out and your Kasa Plug is still disconnecting from Wi-Fi, continue to the next step.

Bring Your Router Closer to the Plug

Another likely cause of this problem is low Wi-Fi signal strength. And this usually happens when your router is positioned too far from the smart plug.

If you think your router is positioned too far from your Kasa Plug, try to bring it closer to the plug—at least 30 feet closer to each other.

More so, you may consider getting a Wi-Fi extender to boost your Wi-Fi network.

Check and Update the Kasa App and the Plug’s Firmware

You may experience some malfunctions (such as Wi-Fi connection issues) if you’re using an outdated version of the Kasa app.

Another fix to try if your Kasa Smart Plug keeps losing connection is to ensure you’re using the current version of the app. If you’re using an Android device, go to Google Play Store and check if the app requires an update—and update it. For iOS users, you can update the Kasa app on App Store.

More so, check whether your Kasa Smart plug’s firmware requires an update. Wi-Fi connection issues may also occur if your plug’s firmware is outdated.

Here is how to check and update your Kasa Smart Plug’s firmware:

  • Open the Kasa app on your phone. Next, tap the Menu icon (looks like three horizontal lines) in the top left-hand corner.
  • Now tap Settings, then tap Firmware Update.
  • If your Smart Plug (and other TP-Link devices) firmware requires an update, you’ll see it displayed on the screen. If the plug requires an update, click on it and follow the instructions in the app to complete the update.

Reset the Plug

If your Kasa Smart Plug still disconnects from Wi-Fi after trying all the fixes above, then the next thing you want to do is factory reset the plug. This usually helps to fix unseen glitches/incorrect settings obstructing the connection.

However, note that resetting your Kasa Smart Plug will remove all previous settings. So, you’ll have to start all over again to set up the plug with the app, set schedules, etc.

That said, here’s how to reset your Kasa Smart Plug:

  • Unplug your Smart Plug from the wall outlet and plug it back in. Ensure it is powered on.
  • Next, press and hold the reset button (located at the top of the Smart Plug) until the plug blinks amber and green.
  • Now the plug is reset. You can start the setup process again.

Closing Thoughts

The fixes in this post should help you resolve Wi-Fi network issues with your TP-Link Kasa Smart Plug.

To recap, if your Kasa Smart Plug keeps losing Wi-Fi connection, start your troubleshooting by rebooting the router and the plug. Next, ensure your router doesn’t switch bands by itself, and bring your router closer to the plug. This should fix the problem.

If the problem persists, check and update the Kasa app and the plug’s firmware. Then perform a factory reset on the plug—as the last resort.

If none of these helps, contact TP-Link Customer Support for help.
