Do I Need to Use a Router With an Xfinity Gateway?

As we have already mentioned, a gateway is a modem/router combo. So, there’s actually no need to connect another router to an xFi gateway. However, there are reasons to do so after all:

  • Improved security: A modem + router network configuration means that you have two devices standing in the way of your phone, laptop, PC, etc. This is bad news for anyone who might have ill intent toward you.
  • Configuration flexibility: You can configure both your modem and your router with various options. The fundamental difference is that you’ll get more configuration features in two devices.
  • Better coverage: The reason there are so many routers on the market is they provide a different network range, signal strength, speed, etc. So, the xFi gateway might have a shorter range than your router.

How to Connect Router to the Xfinity Gateway?

If you’re planning to connect a router to your xFi gateway, it’s not important where you place the gateway because it’s only going to act as a modem. Turn on your Xfinity gateway and wait for the indicator lights to become solid.

Ethernet ports

You need to plug the other end of the Ethernet cable into your router. Make sure that the ethernet cable is properly connected.

Turn on the router and wait until all indicator lights become solid. Now, we need to enable Bridge mode on our gateway. Bridge mode disables the NAT (Network Address Translation) function of your Xfinity gateway, so it essentially becomes a modem.

With bridge mode enabled, you can manage your account with the Xfinity app, but you won’t be able to access all features. Also, you can connect only one device. In bridge mode, the gateway is a modem and provides internet access to one device only (your router).

How to Enable Bridge Mode on the Xfinity Gateway?

Bridging is a term used to describe joining two networking devices to create a unique combined communication link. The bridge is usually formed between the modem and the router, or two routers. 

Bridge Mode Explained

To enable the bridge mode:

  • Connect your laptop to the xFi gateway using an Ethernet cable.
  • Open the web browser and type in the address bar. 
  • From the left pane, select the Gateway option, and then select At a Glance.
  • Enable Bridge Mode
  • The OK button will appear on the screen. Click on it.
  • If your Xfinity doesn’t restart automatically, restart it manually by holding a restart button for a few seconds.
  • Turn off the Xfinity gateway and connect the router to it with an Ethernet cable.
  • Turn on the gateway and the router, and check if you have an internet connection.

How to Enable Bridge Mode on Your Xfinity Gateway


Xfinity, as an ISP, is a superb choice because it has so many plans available, and the prices are competitive. The main perk of their offer is that you can create your personal plan. However, their xFi gateway might not be the best solution for everyone.

So, now you know how to connect your router to an Xfinity gateway, and you understand the reasons people do things like this. Finally, you’ve learned how to enable bridge mode on your xFi. If this doesn’t help, contact Xfinity support, they might have a solution.
