How to Reset TP-Link Deco: Soft Reset, Hard Reset & Troubleshooting

Reset TP-Link Deco

Resetting your TP-Link Deco can fix connection issues, clear forgotten passwords, or prepare the system for a fresh setup. Here’s everything you need to know about resetting any Deco model—fast, clear, and straight to the point.


Two Types of Resets: Soft Reset vs Hard Reset

Soft Reset (Quick Fix, Settings Stay)

soft reset reboots your Deco without erasing your WiFi name, password, or network settings. Use this when your Deco is sluggish or devices keep disconnecting.

When to use:

  • Slow speeds
  • Devices dropping connection
  • Minor glitches

How to do it:

  • Press and hold the Reset button (on the bottom of the Deco) for 1–2 seconds.
  • The LED will blink, the Deco will reboot, and your settings remain intact.

Hard Reset (Factory Reset, Wipes Everything)

hard reset erases all settings—WiFi name, password, configurations—and returns your Deco to factory defaults. You’ll need to set it up again from scratch.

When to use:

  • Constant disconnects that soft reset won’t fix
  • Forgot your WiFi password or admin login
  • Selling or giving away your Deco
  • Network won’t respond at all

How to do it:

  • Press and hold the Reset button for 10 seconds or more.​
  • Watch the LED—it will turn off, then blink yellow (or solid yellow on some models).
  • Release when the LED changes. The Deco will restart and flash blue when ready for setup.​​

If you prefer using the app instead of the physical button:

To Reset a Single Deco Unit:

  1. Open the Deco app.
  2. Tap the Network tab → select your network map.
  3. Tap the Deco unit you want to reset.
  4. Tap the three-dot menu (top right) → select Remove.
  5. Confirm by tapping Remove again.
  6. The unit resets to factory settings. Wait until the LED flashes blue—it’s ready for setup.

To Reset the Entire Deco Network:

  1. Reset satellite units first, one at a time (using the steps above).
  2. Reset the main Deco last (the one connected to your modem/router).
  3. After all units show blinking blue LEDs, you can set up the network again from scratch.

What Happens After a Reset?

After a Soft Reset:

  • Deco reboots
  • All settings stay the same
  • WiFi comes back online in 1–2 minutes

After a Hard Reset:

  • All settings are erased
  • LED will flash blue (pairing mode)
  • You must set up the Deco again using the Deco app

Troubleshooting: What If the Reset Doesn’t Work?

Problem: Reset button doesn’t seem to work

Fixes:

  • Unplug the Deco, wait 30 seconds, plug it back in, wait 2 minutes, then try resetting again.
  • Try holding the reset button while plugging the power back in—keep holding for a few seconds.
  • Use a pin or paperclip to make sure you’re pressing the button properly.

Problem: LED stays red or won’t turn blue after reset

Fixes:

  • Power cycle the Deco (unplug for 1 minute, plug back in).
  • Try resetting again—hold for the full 10 seconds until the LED changes.​
  • If it’s stuck in “recovery mode,” hold reset for just 1–2 seconds to snap it out.

Problem: Deco keeps resetting itself after modem reboots

This can happen if the main Deco loses its connection settings when the modem restarts.

Fixes:

  • After the modem comes back online, power cycle the main Deco.
  • Try a quick 1-second reset press (soft reset) to force reconnection without wiping settings.
  • If that doesn’t work, check if firmware updates are available in the Deco app.

Problem: Factory reset via app didn’t work

Fixes:

  • Use the physical reset button instead (10-second hold).
  • Make sure you’re removing satellite units first, main unit last.

Step-by-Step: Setting Up Deco Again After Hard Reset

Once your Deco is reset and flashing blue:

  1. Open the Deco app on your phone.
  2. Log in with your TP-Link ID (or create one).
  3. Tap “+” to add a new Deco.
  4. Select your Deco model (e.g., M5, X20, XE75).
  5. Follow the app instructions:
    • Connect the main Deco to your modem via Ethernet.
    • Wait for the LED to flash blue.
    • Create your new WiFi network name and password.
  6. Add any additional Deco units by tapping “+” again and placing them within range of the main unit.

  • Soft reset: Use this first for minor issues—slow speeds, random disconnects, one device acting up.
  • Hard reset: Use when soft reset doesn’t work, you’re locked out, or starting fresh with a new setup.

Q: What does the LED color mean during reset?

A: Blinking yellow = reset in progress. Solid yellow = reset complete (on some models). Flashing blue = ready for setup.

Q: Why does my Deco keep losing settings after modem reboots?

A: This is a known issue with some setups. Try a soft reset (1-second press) after the modem comes back online, or update firmware via the app.

Q: Can I reset my Deco without the app?

A: Yes. Use the physical reset button on the bottom of each unit.

Q: What if I only want to reset one satellite Deco?

A: Use the app to remove that specific unit, or press its reset button for 1 second (soft) or 10 seconds (hard).

Q: Do I need to reset all Deco units in my mesh network?

A: For a hard reset of the whole system, yes—reset satellites first, then the main unit last.

Q: How long does a Deco reset take?

A: Soft reset: 1–2 minutes. Hard reset: 2–3 minutes until the LED flashes blue and it’s ready for setup.

Q: Will resetting my Deco disconnect all devices?

A: Yes. A soft reset briefly disconnects devices but they reconnect automatically. A hard reset wipes everything—you’ll need to reconnect all devices manually after setup.

That’s it—resetting your TP-Link Deco is simple once you know the difference between soft and hard resets. Start with a soft reset for quick fixes, and only do a hard reset when you need to wipe everything clean and start fresh.
