TP-Link Smart Plug Won’t Connect to Wi-Fi Troubleshooting (TP-Link Smart Plug Wi-Fi Connection)

TP-link is probably the most famous manufacturer of network equipment in the world. This Chinese company, founded in 1996, is probably the first association when it comes to routers and modems, but it’s also very well known for its smart plugs and other smart home devices.

In today’s era of smart devices, when the number of “smart homes” is increasing, smart plugs occupy a very important place. To work, smart plugs must be connected to Wi-Fi. Thanks to them, users can control other smart devices, regardless of where they are. All they need is a mobile phone and an internet connection.

Sounds great, doesn’t it? However, one common problem that can occur with the TP-Link smart plug is that it cannot connect to Wi-Fi for some reason. This mostly happens when you first set it up, but it’s not uncommon for it to happen afterward.

This is exactly the topic we are dealing with in this article. There are several reasons why your smart plug won’t connect to Wi-Fi, and we’ll show you what you can do to fix the issue.

Below, we will show you seven methods you can try to successfully solve the problem of connecting a smart plug to Wi-Fi. Let’s begin!

How to Set Up a TP-Link Smart Plug

Verify Wi-Fi Settings

It is very important to know that the TP-Link Smart Plug is designed for long-range connectivity and operation. That means it can only support the 2.4 GHz frequency. If your router is set to the 5 GHz band (if 2.4 GHz Wi-Fi is disabled), chances are – your Smart Plug will not connect to Wi-Fi. Hence, be sure to configure the 2.4GHz band in your router’s settings and enable 2.4 GHz Wi-Fi broadcast.

Additionally, go through the following settings:

  • Ensure new connections are permitted by your router.
  • Disable any VPN services that are running on your device.

Try Resetting the Plug

If the problem with the connection of the Smart Plug to Wi-Fi still occurs, then you can try resetting the plug. Follow these instructions:

  • Locate the button on the top or side (depending on the model) of your smart plug.

  • Press the button and hold it (while the device is plugged in). To reset network settings only, hold the button for approx. 5sec, until the LED light starts flashing amber and green alternately.  
  • To reset your smart plug to factory default settings, keep holding the button for about 10sec until it starts flashing amber quickly. Then, you can release the button. 

Note: Resetting to default settings will delete all custom-made settings. Resetting network settings will forget the network settings but will keep all the other custom settings.
