How to Set Up Bridge Mode on Fizz Modem CODA-4680: Complete Step-by-Step Guide

Why Use Bridge Mode?

Fizz ships all Internet subscribers a Hitron CODA-4680 modem/router combo. It works fine out of the box, but power users often want to use their own router (like an Eero mesh system, ASUS RT-AX86U, or UniFi Dream Machine) for better performance and features.

Bridge mode turns the Fizz modem into a simple "pass-through" — it handles the internet connection but lets YOUR router manage Wi-Fi, DHCP, and firewall duties.

Before You Start

You'll need:

• check_circle A computer connected to the Fizz modem via ethernet cable (not Wi-Fi)
• check_circle Your own router ready to plug in
• check_circle About 15 minutes of patience
• check_circle The modem's admin password (we'll cover how to find it)

Step 1: Access the Modem Admin Panel

• 1. Open your browser and navigate to: http://192.168.0.1
• 2. You'll see the Hitron login page
• 3. Default credentials:
• check_circle Username: cusadmin
• check_circle Password: password (or check the sticker on the bottom of your modem)

Pro tip: If "password" doesn't work, try the serial number on the modem's label, or the last 8 characters of the modem's MAC address.

Step 2: Enable Bridge Mode

• 1. Navigate to Gateway → Connection → Mode
• 2. Change from "Router Mode" to "Bridge Mode"
• 3. Click Save/Apply
• 4. The modem will reboot — this takes about 2–3 minutes

Step 3: Connect Your Router

• 1. Plug an ethernet cable from the Fizz modem's LAN port 1 to your router's WAN port
• 2. Power on your router
• 3. Your router should automatically receive a public IP address via DHCP
• 4. Configure your router's Wi-Fi network name and password

Common Issues and Fixes

Can't access 192.168.0.1 after enabling bridge mode:

• check_circle This is normal! In bridge mode, the modem no longer has a web interface accessible at that address
• check_circle To access it again, connect directly via ethernet and use http://192.168.100.1

Internet drops after enabling bridge mode:

• check_circle Unplug the modem power for 30 seconds
• check_circle Plug it back in and wait 3 minutes for it to fully boot
• check_circle Then power on your router

Fizz TV not working after bridge mode:

• check_circle You'll need to enable IGMP Proxy or MLD Proxy on your router
• check_circle Some routers (like Eero) don't support this — you may need to keep one device connected directly to the modem

Performance Improvements

In our testing, switching from the built-in CODA-4680 Wi-Fi to a dedicated router showed:

• check_circle 34% improvement in Wi-Fi range
• check_circle 22% faster average speeds on Wi-Fi 6 devices
• check_circle Significantly reduced bufferbloat (better for gaming and video calls)
