TP-Link Smart Plug Blinking Blue: Troubleshooting Guide

You’re not alone if you’re having trouble with your TP-Link smart plug blinking blue. This issue can be frustrating, but it’s not uncommon.

Luckily, you can try a few things to troubleshoot the problem and get your smart plug back up and running.

Check Your Wi-Fi Connection

One of the most common reasons a TP-Link smart plug blinks blue is a poor Wi-Fi connection.

To troubleshoot this issue, check your Wi-Fi connection and make sure it’s stable and strong.

If your Wi-Fi signal is weak, try moving your router closer to the smart plug or using a Wi-Fi extender to boost the signal.

Reset the Smart Plug

Another solution to the blinking blue light problem is to reset the smart plug. To do this, follow these steps:

  1. Unplug the smart plug from the outlet.
  2. Wait at least 10 seconds.
  3. Plug the smart plug back into the outlet.

Once you’ve reset the smart plug, try setting it up again and see if the problem persists.

Check for Firmware Updates

If your TP-Link smart plug is still blinking blue, check if any firmware updates are available.

To do this, open the Kasa app on your smartphone or tablet and go to “Settings” > “Firmware Update”.

If there’s an update available, follow the on-screen instructions to download and install it.

Check Your Network Settings

Another possible solution is to check your network settings. Ensure your router is set up to support 2.4GHz Wi-Fi and your smart plug is connected to the correct network.

You can check this by going to “Settings” > “Wi-Fi” on your smartphone or tablet.

Factory Reset the Smart Plug

If all else fails, you can try factory resetting the smart plug. This will erase all settings and data on the device, so ensure you’re okay with starting from scratch before proceeding. To factory reset the smart plug, follow these steps:

  1. Press and hold the button on the smart plug for 10 seconds.
  2. The LED light on the smart plug will blink red and green.
  3. Release the button and wait for the smart plug to restart.

Once the smart plug has restarted, you must set it up again using the Kasa app.


A TP-Link smart plug blinking blue can be frustrating, but you can do plenty of things to troubleshoot the problem.

Whether checking your Wi-Fi connection, resetting the smart plug, or doing a factory reset, solutions are available for this common issue.

With a little bit of patience and persistence, you’ll be able to get your smart plug back up and running in no time.
