TP-Link Deco X60 Setup (Wi-Fi 6)

One of the most famous WiFi networking devices is Deco X60 mesh system which provides Wi-Fi 6 technology to the users.

This setup & troubleshooting guide will present a quick and correct installation process which help you to complete the Deco X60 setup easily.

TP-Link Deco X60 Setup

Connection with Modem

Pick the one closest to your modem (or gateway).

Ethernet from modem LAN port to Deco any port.
Power it on. White light means it’s booting, flashing blue means it’s ready to pair.

If it’s yellow for a while? Just wait. If it stays yellow forever, reboot the modem and the Deco.

Configuration with Deco App

Download the Deco app. Everything runs through that app – no web UI for initial setup. iOS or Android, doesn’t matter, just grab it.

Open the app, create a TP-Link account if you don’t already have one. Yeah, annoying, but you need it.
Take the first Deco unit – this is your main one. Plug it into your modem using the included Ethernet cable. Power it on.
The LED should go yellow, then eventually pulse blue. If it doesn’t, hold the reset button for 10 seconds and try again.
Hit the + sign, choose “Deco X60.” The app will walk you through – it’s pretty simple. It’ll find the unit (thanks to Bluetooth), then ask you for your ISP details if needed. Most cases, it’s just DHCP, so no extra info required.
Pick your Wi-Fi name and password. This is the SSID your entire mesh will use. No separate 2.4 and 5 GHz names here — Deco combines them.
Once the main one’s up, the app will say “Add another Deco.” Do it now or later, doesn’t matter, but I’d do it now so the mesh stabilizes quicker.
Plug in the second Deco somewhere halfway between the main one and where you want coverage. Power on, wait for pulsing blue, then let the app find it. Repeat for any more units.
Start middle-ish, then adjust later if coverage sucks. The app has a signal strength checker in the device settings.
Update the firmware. Takes a few minutes, then everything reboots.

Configuration with tplinkdeco.net

Tplinkdeco.net only works when you’re connected to the Deco network. Like, physically on Wi-Fi or through the main Deco via Ethernet.
If you’re on mobile data or some other random Wi-Fi, forget it. It won’t load. Switch over first.
Now, once you’re connected, hit this in your browser: tplinkdeco.net, doesn’t open, here’s the usual suspects:
- Wrong network – You’re probably on your ISP router or a guest network. Double-check.
- DNS hiccup – Sometimes it just doesn’t resolve. Quick hack: try the IP instead. Most Decos use 192.168.68.1. So, type that in your browser.
- Browser cache weirdness – Chrome loves to be stubborn. Clear cache or just try incognito. Or use another browser. Firefox usually works like a champ.
So now you’ve got the Deco login page. Here’s where people mess up: there’s no “router admin password”. Deco uses your TP-Link ID.

That’s the same email/password you used in the Deco app. So, log in with that. Two-step authorization? Yup, if you enabled it, have your phone handy.

Change WiFi password

Grab your phone. Download the TP-Link Deco app if you don’t already have it. It’s on iOS and Android.
Open the app and sign in. Same account you used during setup. If you forgot it, use the email reset thing.
Pick your network. If you have more than one Deco network on the account, make sure you’re in the right one.
Go to Wi-Fi settings. Bottom menu → More → Wi-Fi Settings.
Edit the password. You’ll see your current SSID and password. Tap the password field, type the new one. Hit Save.

Update the Deco setup

In the Deco app, tap the More button (bottom right).
Go to Update Deco.
If there’s an update, you’ll see it. If not, it’ll say you’re on the latest.
Hit Update All if there’s a new version.

Sync Nodes After Setup

Grab the node you’re trying to add. Plug it in close to the main one – like, same room close. Don’t leave it across the house.
For whatever reason, Deco hates doing long-distance relationships during setup. Wait for the LED to go pulsing blue.
If it’s yellow or red or doing something weird, hold the reset button for about 10 seconds until it turns yellow, then let it reboot.
Back in the app, tap Add Deco > Deco X60, follow the steps, and let it search. If it spins forever and says “can’t find,” don’t panic yet.
Close the app, relaunch, and try again. Still nothing? Pull the power from the node, wait like 10 seconds, plug it back in. Try adding again.

Troubleshooting Tips: Deco X60 Setup

1. Check the Basics

First, power cycle everything. Modem, Deco, all of it. Unplug for 30 seconds, plug back in. Half the time the “problem” is something dumb like a stuck handshake between your ISP and the Deco.

2. Modem + Deco

If your modem is a gateway (modem + router combo), you’ll want bridge mode. Otherwise, you’ll get double NAT and weird connectivity issues.

Go into the modem settings (usually some 192.x.x.x IP in the browser).
Enable bridge mode OR turn off the Wi-Fi and DHCP on the modem.

If you can’t find bridge mode, call your ISP. Yeah, I know, but it’s worth it.

3. App vs. Reality

The Deco app is nice until it’s not. Sometimes it just refuses to detect the main unit. If that happens:

Reset the Deco (hold the reset pin for ~10 sec).
Close the app from memory, reopen, and try again.
Make sure Bluetooth is on because the app needs it during setup.

4. Firmware Updates

Before you start connecting satellites, update the main Deco firmware. The app usually nags you about it, but if it doesn’t, check manually. Old firmware can cause drops, random disconnects, and general chaos.

5. Satellite Placement

Don’t stick the extra units in the dead zones. They need a strong signal from the main Deco to repeat it. Rule of thumb: if your phone gets one bar in a spot, the satellite will do worse. Start closer, then move out.

6. ISP Authentication Weirdness

If your ISP uses PPPoE (common with fiber), make sure you enter the username and password during setup. If you have no clue what that is, call your ISP—they know.

7. Last Resort

Factory reset everything and start fresh. Sometimes it’s faster than troubleshooting ghost issues for two hours.
