A flashing yellow light on your TP-Link Deco indicates a startup or reset. This occurs often after powering on and off, restarting, or setting up the gadget.

If the yellow light keeps blinking, the Deco unit may be stuck or unable to boot. That's when you need to do something.

This guide aims to tell you precisely what the flickering yellow light signifies, why it occurs, and what you can do to solve it. Let's take it apart!

What does the yellow light that blinks mean?

Let's keep things clear.

The flickering yellow light typically implies that your Deco is turning on. It's not broken. It hasn't been hacked. It's just starting up.

If it keeps flashing for a long, say more than a minute or two, it can be stuck in the boot process. And that's when it starts to grate on my nerves.

This is what each color of Deco light means:

• Solid Yellow: The device is on, but not ready yet.

• Blinking Yellow: Trying to start or reset.

• Blue flashing: ready to set up.

• Solid Green & White: It means everything is OK.

• Red: Something is wrong

So, yes, the Deco yellow light is part of the typical start-up process.

Why Does It Keep Flashing Yellow?

The point is, it shouldn't do that all the time. If your Deco is caught on that yellow flash, something is getting in the way. It might be:

• A problem with the electricity (a loose plug or an unsteady connection)

• Firmware upgrade that was stopped or failed

• The unit was just reset, but the configuration wasn't finished.

• A problem with the hardware (not common, but conceivable)

• The Ethernet connection from the modem is broken.

Are you serious? One of the first three is the right answer 9 times out of 10. So don't worry. We have solutions.

How to Stop the Yellow Light from Blinking Quickly?

Here’s the main point. Follow the give points in this sequence provided:

1. Just wait it out

If you just plugged it in or restarted it, give it a good 1–2 minutes. For a short while, that Deco yellow light that blinks is typical.

But what if it keeps glowing yellow after a few minutes? Go on to step two.

2. Unplug & plug it back in.

This simple action fixes more computer issues than people think it does.

• Take the Deco out of the wall

• Wait 15 to 30 seconds.

• Make sure it is properly plugged back in.

Sometimes it's simply a glitch in the boot. This starts the power cycle again and lets the Deco attempt again, clean.

3. Look at all the wires, especially the ethernet one.

Your Deco requires a strong connection to the modem or main router.

• Check to see whether the ethernet cable is broken.

• Put it back into both the Deco and the modem/router.

• If you can, try an alternative port on the modem.

Sometimes the Deco seems like it's not starting up, but it's simply not receiving any internet from the modem.

4. Use the Deco App to Change Settings

Open the Deco app if the light is glowing yellow but you haven't paired it yet. To reconnect or finish setting up, follow the instructions in the app. The app will let you know what stage it's in.

If the Deco becomes reset by purpose or by accident, the app is your only way to get it back.

5. Reset the Deco, but only if it is required

Reset it if you've done the fundamentals and it still blinks like it's caught in starting purgatory. But keep in mind that this will erase all settings.

This is how:

• Find the reset button, which is a little hole on the bottom.

• Use a paperclip or pin to keep it down.

• Wait for the Deco yellow light to change to a flashing blue light.

Now you can use the Deco app to set it up again.

6. Use a Different Power Outlet

It may seem ridiculous, but electricity that isn't consistent may screw with routers and extenders. If you're in an older building with strange wiring, try connecting the Deco into a different wall outlet.

It may make a bigger impact than you imagine.

A Quick Note About Firmware

Things don't always reboot correctly after an update. That may also make the Deco yellow light loop happen.

If you’ve accidentally or intentionally altered your firmware, restarting and setting up the device using the app may cure it.

Check whether a new programme version is ready or if the update went incorrect.

Final Words

Now, you know that deco yellow light isn't the worst thing that has happened to your device. Your Deco is merely letting you know that it is stuck or hasn't really woken up yet.

It may be anything minor. Maybe your device is asking for a “Reset”.

Most of the time? You can fix it by restarting it, plugging it back in, or re-pairing it using the app.

Frequently Asked Questions

Q1: Does the flickering yellow light mean my Deco is broken?

Not always. It typically indicates that it won't boot or reset. Before you think your hardware is broken, try the fast remedies.

Q2: Is it possible to use Deco to increase the range of my Orbi router?

Not in the usual way that mesh does. Deco and Orbi don't work together. It's best to stay with the same brand.

Q3: Why does my Deco continually turn itself off?

It might be a poor power supply or an insufficient firmware upgrade. Make sure your app, cables, and outlet are all stable.
