🔍 Introduction: Why Use an ONU as an AP Bridge? The ZTE ONU ZL2113X v2 comes equipped with advanced features that allow it to function beyond its basic purpose. With the latest firmware update (version 2213 ), it now supports bridge mode , enabling it to act as a wireless access point or even a mini Layer 2 switch. This capability is especially useful in scenarios where you want to: Extend Wi-Fi coverage in large homes or offices Avoid deploying extra hardware Save costs while increasing flexibility Support dual services like PPPoE and Hotspot simultaneously Let’s dive into how to make this happen.

🧰 Prerequisites Before Starting

Before proceeding with the configuration, ensure you have the following: ITEM DESCRIPTION ONU Model Zimmlink ONU ZL2113X v2 Firmware Version At least 2213 for AP Bridge support Connection Type FTTH PON Network Tools Required Ethernet cables, computer/laptop, SSH/Telnet client (optional) Services Used PPPoE + Hotspot via VLANs 💡 Note: Make sure both ONUs are registered on the same OLT and are part of the same VLAN environment. 🛠️ Step 1: Update Firmware to 2213 on ONU #2 To enable AP Bridge functionality, ONU #2 must be running firmware version 2213 . ✅ Steps to Update Firmware: Access the Web Interface Open a browser and go to the default IP: http://192.168.1.1 Login with username: superadmin and password: suportadmin Navigate to Upgrade Section Go to System > Maintenance > Firmware Upgrade Upload the .bin file for firmware version 2213 Reboot the ONU After upload completes, reboot the device Verify Firmware Version Once rebooted, check under System > Device Info 📦 Firmware files can be obtained from official ZTE channels or authorized distributors.

⚙️ Step 2: Configure ONU #1 – Main FTTH Gateway ONU #1 acts as the main gateway, handling both PPPoE and Hotspot services. These services will be passed downstream to ONU #2 via a UTP cable. 🔐 Login Details: Username : superadmin Password : suportadmin 📋 Basic Setup Summary: SERVICE VLAN ID PORTS USED SSID PPPoE 120 LAN 4 SSID 1 Hotspot 131 LAN 1-3 SSID 2 🧩 Detailed Configuration: 1. PPPoE Profile Setup Menu : Services > PPPoE Enable DHCP Server ✅ Create a new profile: Name: PPPoE_Profile VLAN ID: 120 Binding Options: SSID 1, LAN 4 Username & Password: Provided by ISP Apply settings 2. Hotspot Profile Setup (Bridge Mode) Menu : Services > Bridge Create a new profile: Name: Hotspot_Bridge VLAN ID: 131 Binding Options: LAN 1, LAN 2, LAN 3, SSID 2 Service Type: Internet DHCP Server: ❌ (Uncheck) DHCP Transparent Transmission: ✅ Apply settings 3. Wireless Settings SSID 1 : Name: PPPoE_Home Security: WPA2-PSK (or open for testing) Enable: ✅ SSID 2 : Name: Hotspot_01 Security: None (for hotspot simplicity) Enable: ✅

🔄 Step 3: Connect ONU #1 to ONU #2 via UTP Cable Now that ONU #1 is set up, connect it to ONU #2 using a standard UTP Ethernet cable . 🔗 Connection Mapping: FROM TO ONU #1 LAN 1 ONU #2 LAN 1 This allows ONU #2 to receive the Hotspot service from ONU #1.

🧪 Step 4: Configure ONU #2 – Set as AP Bridge Once firmware 2213 is installed, you can reconfigure ONU #2 to operate as an AP Bridge . 🔘 Change Expon Mode to Ethernet Menu : Manage > Expon Mode Select: Ethernet Apply and Reboot After rebooting, log back in.

🧩 Configure Bridge Profile Menu : Network > Bridge Create a new profile: Name: AP_Bridge Type: Bridge Service: Internet Binding Options: LAN 1, LAN 2, LAN 3, LAN 4, SSID 1 DHCP Server: ❌ DHCP Transparent Transmission: ✅ VLAN Mode: Transparent Apply and save. 📶 Step 5: Configure Wi-Fi on ONU #2 To provide extended wireless coverage: SSID : Hotspot_02 Security : None (or custom based on use case) Enable SSID : ✅ This SSID will now serve clients connected wirelessly to ONU #2. 🧪 Step 6: Test Connectivity On a Laptop Connected to ONU #2: Run Command Prompt: bash "ipconfig"

Ensure IP is assigned by Hotspot server (e.g., 192.168.131.x) Try accessing a website: "ping google.com"
