Bridge mode vs router mode
Wondering what bridge mode is and whether you should use it? Here's a quick explanation of the difference, when to use bridge mode, and how to switch it on if needed.
What’s the difference?
Your modem or router typically runs in router mode by default. This means it’s doing several things at once:
Assigning local IP addresses via DHCP
Translating network traffic using NAT (Network Address Translation)
Routing traffic between your home network and the internet
In bridge mode, those features are switched off. The Nokia unit stops handling routing and WiFi, and instead passes the internet connection directly to another router, which takes over all networking functions.
When to use bridge mode
Bridge mode is useful when:
You’re using a third-party router and don’t want double NAT or IP conflicts
You’ve got a mesh system (like Eero or Google Nest Wi-Fi) that prefers to manage routing itself
You’re running a business firewall or advanced networking setup
If you're not sure whether you need bridge mode, it’s best to leave things as they are or check with support first.
How to enable bridge mode
If you’re using a Splice-supplied NTD/ONU, bridge mode can usually be enabled in the web interface:
Open a browser and go to http://192.168.18.1
Log in with your admin username and password (check the sticker on the device if you’re unsure)
Look under Network Settings, Internet Settings, or Advanced Settings
Find the option for Bridge Mode or Modem Mode and enable it
Save and reboot if prompted
Note: Enabling bridge mode disables built-in WiFi and all routing functions. You’ll need to connect a separate router to keep your network running.
