Deco Flashing Yellow Light : What It Means & How to Fix It

TP-Link Deco is a reliable mesh Wi-Fi system, but like any tech device, it can sometimes show unusual behavior. One common issue users encounter is the Deco flashing yellow light. If you’ve noticed this on your device, don’t worry—this guide explains what it means and how to fix it.

What Does a Flashing Yellow Light on Deco Mean?

When your TP-Link Deco flashes yellow, it usually indicates that the unit is starting up or in recovery mode. In some cases, it might also suggest a firmware issue or that the unit is unable to connect to the internet.

Common Scenarios:

• Normal boot-up: Yellow light flashes for 1-2 minutes, then changes color.
• Stuck in yellow: Flashing yellow for more than 5 minutes might signal a problem.
• After firmware update: Sometimes occurs post-update and may require a reset.

How to Fix Deco Flashing Yellow Light

Let’s walk through the most effective ways to troubleshoot and fix the yellow blinking light issue.

1. Wait a Few Minutes

If the device was just powered on, give it 2-3 minutes to complete its startup process. If the light changes to green, blue, or red, your Deco is functioning normally.

2. Power Cycle the Deco

Unplug the Deco from the power source, wait for 10 seconds, and plug it back in. This often clears up temporary glitches.

3. Check Internet Connection

Ensure your modem is online and working. If there’s no internet access from the source, Deco won’t be able to establish a connection.

4. Reset the Deco Unit

If the flashing yellow continues for over 5 minutes:

• Press and hold the Reset button (usually at the bottom) for 10 seconds.
• Wait for the yellow light to turn solid and then start flashing again.

This action puts your Deco into setup mode, allowing you to reconnect using the app.

5. Reconfigure Using the TP-Link Deco App

Open the TP-Link Deco app and follow the tplink deco setup steps to reconnect your unit. Make sure your smartphone is connected to the Deco’s Wi-Fi signal and follow the prompts.

Why Your Deco Keeps Going Offline

If Deco keeps going offline, this could be related to several factors:

• Weak signal from the modem or ISP issues
• Outdated firmware
• Incorrect Deco placement (too far from main unit)
• Hardware faults

Make sure all units are updated and within range of one another. You may also want to run a diagnostic from the app to identify potential issues.

When to Contact TP-Link Support

If none of the above steps resolve the problem, the Deco unit might be faulty or experiencing a firmware bug. Reach out to TP-Link support for further assistance or a potential replacement.
