Put Gateway in Bridge Mode

To avoid Xfinity eero issues caused by double NAT, a key step is enabling bridge mode on your gateway. This turns off the routing functions and allows your Eero to handle networking duties. Double NAT conflicts are the main cause of Xfinity Eero Issues since the gateway and Eero router have overlapping functions.

Follow these instructions to enable bridge mode on common Xfinity and Eero gateways:

Xfinity Gateway Bridge Mode Setup

  1. Connect a device directly to your Xfinity gateway via ethernet.
  2. Open a web browser and visit to access the admin screen.
  3. Login with username “admin” and password “password” (or custom if changed).
  4. Go to Gateway > Connection > Bridge Mode and check Enable.
  5. Confirm you want to disable routing functions. The gateway will restart.

Eero Bridge Mode Setup

  1. Access your Eero app and go to Settings > Network Settings > Enable Bridge Mode.
  2. Follow the on-screen instructions to turn on bridge mode.
  3. Your Eero will restart and move into bridge mode, allowing a single external router on the network.
  4. Connect your Xfinity gateway ethernet to the WAN port on the Eero.

Be sure to disconnect all wired devices from the Xfinity gateway after enabling bridge mode. Only your Eero’s ethernet ports should be used when bridged.

If you need any assistance enabling bridge mode on your specific Xfinity or Eero model, check their support sites or contact technical support. With this key routing change, you can avoid many connectivity problems.

Step-by-step instructions for enabling bridge mode are crucial when troubleshooting Xfinity Eero Issues caused by double NAT conflicts.

Putting a Modem/router Combo Into Bridge Mode with Eero

Enabling bridge mode on your Xfinity gateway is a key step in resolving Xfinity Eero Issues caused by routing conflicts. Resetting your Eero system can help troubleshoot Xfinity Eero Issues by clearing any corrupted settings or connectivity problems. Some other things that you should consider include:

  • Bridge mode disables routing and WiFi capabilities of your existing modem/router to allow Eero to handle it.
  • Instructions vary widely by ISP and device model, so check your provider’s site or call support if unsure.
  • Set up your Eero network first before enabling bridge mode to avoid interruptions.
  • Access your modem/router’s admin interface to enable bridge mode in the settings.
  • You’ll likely need to reboot the modem/router after enabling bridge mode.
  • Disconnect all devices from LAN ports on the modem/router once bridged.
  • Connect your Eero gateway to LAN port 1 on the bridged modem.
  • Use a switch to add more wired devices by connecting it to the Eero, not directly to the bridged modem.
  • You may need to rejoin the WiFi network on wireless devices after bridging.
  • Contact your ISP if you have any issues getting your modem/router into bridge mode.
  • Take your time and follow instructions carefully to get your network transitioned properly.

Reset the Eero System

If you are still experiencing Xfinity eero issues after putting your Xfinity gateway into bridge mode, a factory reset of the Eero mesh system is recommended. Resetting the Eero clears out any old or conflicting settings that may be causing problems with connectivity and stability. Resetting your Eero system can help troubleshoot Xfinity Eero Issues by clearing any corrupted settings or connectivity problems.

First, unplug your primary Eero router for at least 1 full minute after enabling bridge mode on the Xfinity gateway. This clears the cache and ensures the Eero starts up fresh detecting the bridged gateway.

Next, you can factory reset the Eero system either through the Eero app or using the reset button on the back of the device. In the app, go to Settings > Network Settings > Factory Reset. This will reboot the whole mesh network to default settings.

Alternatively, press and hold the reset button on the back of your primary Eero router for at least 10 seconds until the LED blinks blue. Keep holding until the light flashes rapidly and the system restarts. All other Eero units will follow suit and reset as well to re-establish the mesh network.

After the reset, you can set up your Eero network again as normal through the app. This often resolves Xfinity eero problems caused by outdated, corrupt or conflicting settings on the Eero side. Resetting gives you a clean slate to re-pair with the bridged Xfinity gateway. Check that you now have stable internet connectivity. If not, contact support or consider firmware updates next.
