Configuring a PHN Portal Device with Eero Router

The PHN Portal is a network device that creates a captive portal experience for your guest Wi-Fi network. When paired with an Eero router, the Portal allows you to collect guest information and provide a customized sign-in experience for visitors connecting to your network.

Benefits of the PHN Portal

  • Guest Data Collection: Capture guest email addresses to build your direct booking database
  • Personalized Sign-In Experience: Create a branded portal page that matches your property
  • Automatic Device Recognition: Phones and tablets prompt for sign-in, while other devices connect seamlessly
  • Real-time Monitoring: Track portal status and guest connections through the PHN Dashboard

What You'll Need

Before you begin: Ensure you have the following items ready:

  • PHN Portal device
  • Included network cable (Ethernet cable)
  • Included power adapter
  • Eero router with available Ethernet port
  • Mobile device with the Eero app installed
  • Access to your PHN Dashboard

Step-by-Step Setup Instructions

Part 1: Connect the PHN Portal

If you haven't already connected and powered on your PHN Portal device, follow the instructions in Connecting Your PHN Portal for the First Time, then return here once the status light is green.

Part 2: Eero App Configuration

1. Create a DHCP Reservation

  • Open the Eero app on your mobile device
  • Navigate to Settings from the bottom menu
  • Select Advanced networking > Reservations & port forwarding > Add a reservation
  • Find the device with a name that starts with "portal-" For example: "portal-8b247h1a"
  • Tap on this device to select it
  • Tap SAVE to create the reservation

3. Copy the IP Address

  • Locate the IP address shown for the Portal device
  • It will look similar to: 192.168.4.21
  • Highlight and copy the complete IP address
  • Tap SAVE to create the reservation

Important: Keep this IP address copied to your clipboard—you'll need it in the next step.

4. Configure Custom DNS

  • In the Eero app, navigate back to Settings
  • Select Advanced networking > DNS
  • Tap Custom DNS
  • Paste in the IP address you copied from the previous step
  • Tap SAVE

5. Wait for Router Reboot

  • Your Eero router will automatically reboot to apply the DNS changes
  • This process typically takes 1-2 minutes
  • Wait for the Eero app to confirm that your network is back online

Confirm:  The Guest wifi network setting should be set to off. Guest networks are limited in function and cannot support captive portal interactions.

Confirm:  Advanced networking > IPv6 should be set to off. Router will restart after changing.

Testing Your Portal Configuration

1. Turn off Setup Mode

  • Open your PHN Dashboard in a web browser
  • Navigate to Devices from the left menu
  • Click on your Portal device to view its settings

2. Test with a Mobile Device

  • Disconnect your phone from the Wi-Fi network (if currently connected)
  • Open your phone's Wi-Fi settings
  • Select your Wi-Fi network and join
  • If using a password-protected network, enter the Wi-Fi password when prompted
  • A sign-in page should appear automatically within a few seconds

3. Verify Portal Page Content

  • The sign-in page that appears should match the preview shown in your PHN Dashboard
  • Navigate to Location > Portal settings to view the expected layout
  • If needed, adjust the layout and type of information you collect

4. Understand Device Behavior

  • Devices that will prompt for sign-in: Phones, tablets, laptops
  • Devices that will connect without sign-in: Baby monitors, game consoles, smart TVs, IoT devices

Note: Some devices may cache network settings. If you don't see the portal page, try forgetting the network on your device and reconnecting.
