What Does a Deco Flashing Yellow Light Really Mean?

A solid yellow light on your TP-Link Deco usually indicates that the device is starting up. This typically occurs after a reboot or when you plug in the Deco unit for the first time. It’s crucial to keep an eye on how long the yellow LED remains in this state even if it’s a startup indicator and not an error.

The device may be stuck during bootup if the deco yellow light lasts longer than two or three minutes. Try following actions in similar situations:

• After ten seconds, unplug the Deco and then re-plug it.
• Watch to see whether it changes to pulsating blue, indicating that setup is complete.
• In contrast, a pulsing yellow light indicates that the Deco is going through a factory reset. 
• This occurs when the reset button is depressed for an extended period of time, usually longer than 10 seconds. When the reset is finished, it should turn blue. The reset might have failed if it doesn’t.
• You can start the setup as soon as the Deco starts to pulse blue. To accomplish this:
• Install the TP-Link Deco App on your smartphone.
• Your phone will show up as “Deco_XXXX” when you connect it to the Deco’s Wi-Fi.
• To create or log into a TP-Link account, open the app and follow the instructions.

Set up your Wi-Fi network configuration.

• As an alternative, access deco login and configuration options by going to tplinkdeco.net from a device that is linked to the Deco’s Wi-Fi. Keep in mind that you may only access this web interface when you are connected to the Deco network.

Remember to:

• Make use of the original power supply.
• The Deco should be kept in a location with good ventilation.
• When updating the firmware, avoid unplugging.
• A hard reset might be necessary if the yellow light persists without changing. Holding down the reset button for a single second causes the LED to flicker first yellow and then blue.
