1. Connect Your Router to the ONT

Connect the WAN port of the TP‑Link Deco BE25 (BE5000) router to the first port (LAN1 or GE1) on your Optical Network Terminal (ONT) using an ethernet cable. Sometimes we connect to the second port instead of the first — check your Welcome email instructions to make sure which port you should use. Ensure the router is powered on and that your computer or smartphone is connected to the router via Wi‑Fi or a LAN cable.

2. Setup via the Deco App

It is highly recommended that you use the Deco App for this device. If you manually configure, you won’t have access to all configuration options. Download the Deco App:

• Android (Google Play)
• iOS (App Store)

You will need a TP‑Link ID to login or create an account. Once logged in:

• Tap “Let's Begin.”

• If this prompt does not show, navigate to the Network tab, tap “+”, and select “Create a Network.”

• Search for your Deco model and select it.

• Follow the app prompts.
• Once connected to Deco Wi‑Fi/Bluetooth, disable mobile data and continue with in-app prompts.
• When prompted to select Internet Connection Type = DHCP (Dynamic IP):
  • If ISP Profile option appears, click it to enter VLAN settings:
  • IPTV/VLAN = On
  • Mode = NZ UFB (or Custom if New Zealand UFB is not available)
  • Internet VLAN ID = 10
  • Internet VLAN Priority = 0

2.1 Manually Access the Router’s Admin Panel

Open a web browser on a connected device and enter http://tplinkdeco.net. Log in using the default credentials:

• Username: admin
• Password: admin

If you have changed the credentials and cannot remember them, proceed to Step 8 for resetting the router. You can view system status and Deco information here, but most configuration requires the Deco App.
 

3.0 Internet Connection Type Settings (DHCP)

In the Deco App:

• Navigate to Internet Settings.
• Set the Internet Connection Type to Dynamic IP (DHCP).
• Click Save to confirm the changes.

3.1 View Deco Status & System Status

Once logged in, you can view your Deco’s status and system settings. The web interface only allows viewing — configuration must be done via the Deco App.

4. Configure VLAN Settings with Deco App

In the Deco App:

• Go to More > Advanced > IPTV/VLAN.
• Enable IPTV/VLAN.
• Click Mode and select “New Zealand UFB” or “Custom.”
• Set the following:
  • Internet VLAN ID: 10
  • Priority: 0
• Click Save to finish setup.

5. Save the Configuration

After entering VLAN and DHCP settings, click Save. The router may restart to apply the settings — wait a few minutes for completion.

6. Verify Internet Connection

Check the WAN/Internet LED on the Deco — it should be solid green if connected. On a connected device, try opening a website to confirm connectivity.

7. Troubleshooting (If Needed)

If the internet is not working:

1. Restart both the ONT and the Deco by unplugging them for 30 seconds, then plug back in.
2. Double-check VLAN and DHCP settings in the Deco App.
3. Ensure the Ethernet cable is securely connected to the correct ports.

8. Reset the Deco (If Required)

To reset:

1. Locate the reset button on the Deco unit.
2. Press and hold for 10–15 seconds using a pin or paperclip.
3. Release when the LEDs flash — Deco will reboot to factory settings.
4. Log in via the Deco App and repeat setup from Step 2.
