ECO Mode is a power-saving feature available on routers that reduce the energy consumption of the device. By lowering the power output of the router, ECO Mode helps to decrease electricity usage, which is beneficial for both the environment and your utility bills.

For TP-Link routers, the ECO mode contains three parts:

1. Power Mode

Power Mode is a feature within ECO Mode that allows the router to operate at a lower power output. This reduces the energy consumption of the device, leading to savings on electricity bills and a decrease in the router’s environmental impact. It may result in a slightly reduced wireless signal range and speed.

2. Wireless Schedule

The Wireless Schedule feature lets you set specific times for the Wi-Fi signal to be turned off. This is particularly useful for conserving energy during periods when the network is not in use, such as late at night or during working hours when no one is home. By scheduling these times, you can ensure that your router is not using unnecessary power.

3. LED Control

LED Control allows you to turn off the LED lights on your router at specific times. This feature is beneficial for reducing light pollution in your home, especially at night, and can also contribute to slight energy savings. You can set a schedule for when the LEDs should be off, providing a more comfortable living environment.

Set up ECO mode through the web UI:

Log in to the web-based interface of the router. If you don’t know how to do that, please refer to How do I log into the web-based Utility (Management Page) of TP-Link wireless router?
Turn to Advanced>System>ECO Mode. On this page, select the level of Power Mode effectiveness as well as the Effective Time.
Then click on the hyperlinks mentioned in the note below to jump to the LED Control and Wireless Schedule settings to complete the corresponding configurations.
