Bridge mode

Most people won’t need bridge mode, but for those who do, we’ve outlined some recommended setups below.

When to use Bridge mode: Bridge mode is only needed when encountering specific cases of Double NAT. For most people, Double NAT does not affect Wi-Fi performance. But it can be an issue if you play online games or use IP address assignments, port forwarding rules, and UPnP. Learn more about Double NAT and when you might need Bridge mode.

Does Google Wifi support Bridge mode?

Yeah, but it will only work if you’re using a single Wifi point. If you’re creating a mesh network with multiple Wifi points, your Primary Wifi point cannot be in Bridge mode. This is because the Primary Wifi point needs to do special things to control settings and communication within your Wi-Fi network. If it’s in bridge mode, you’ll lose some of Google Wifi’s key features.

How do I enable bridge mode?

If you are only using a single Google Wifi point and Double NAT is causing problems, you have two options:

Enable bridge mode on your ISP-provided modem/router (RECOMMENDED)

The best solution to double NAT is enabling bridge mode on your modem/router combo.

Log into your router or modem/router combo and find its settings to enable bridge mode. To access your router’s settings, you might have to open an internet browser, and enter your router’s IP address in the address bar. Like this:

Details vary depending on the device. Many ISPs and manufacturers provide instructions on how to do this.

Enable bridge mode on your primary Wifi point (NOT RECOMMENDED)

Note: Bridge mode will only work if you’re using a single Google Wifi point. If you’re creating a mesh network with multiple Wifi points, your Primary Wifi point cannot be in Bridge mode.

While all additional Wifi points are always in bridge mode by default, we don’t recommend turning your Primary Wifi point into a bridge. This is because the Primary Wifi point needs to do special things to control settings and communication within your Wi-Fi network. If it’s in bridge mode, you’ll lose some of Google Wifi’s functionality:

  • Priority device will be unavailable
  • DNS can’t be edited
  • WAN settings can’t be edited
  • Guest Wi-Fi
  • Wi-Fi speed results in Network check. (But download and upload results will still work.)
  • Philips Hue pairing and controls

Additionally, bridge mode disables many of Google Wifi’s security protections. This is because your upstream router (the modem/router combo in the above scenario) is the one performing DNS steering, packet inspection, executable patching, etc.

Google Wifi’s automatic security updates maximizes your privacy and security. Its protective features are most effective -- and in some cases, only effective -- when all traffic passes through your Primary Wifi point (instead of another router).

If you have a 3rd party router, you can wire a Primary Wifi point to it, then “mesh” additional Wifi points downstream. See here for detailed steps.

Still want to turn your primary Wifi point into a bridge? Ok, here’s how:

1. Open the Google Wifi app.

2. Tap the settings tab, then Network settings.

3. Tap Advanced networking > Device mode > your Wifi point > Bridge mode.

4. Tap Save.

You cannot transition your primary Wifi point into Bridge mode if your WAN IP is a public IP address. To enable Bridge mode, there needs to be another router between your modem and your primary Wifi point. If your primary Wifi point’s WAN port has a public IP, that means it’s directly connected to your modem. In this scenario, the Bridge mode option in the app will be unavailable in the app.
 

Additional questions

How do I disable Bridge mode?
  1. Open the Google Wifi app.
  2. Tap the settings tab, then Network settings.
  3. Tap Advanced networking > Device mode > your Wifi point > NAT (standard) mode.
  4. Tap Save.
When do I need Bridge mode?

Connecting two routers can extend the Wi-Fi coverage in your home. But when you have two routers -- each with their own private Wi-Fi network -- your personal devices can have a hard time communicating with each other. This scenario is called Double NAT.

For example, let’s say you want to wirelessly print a picture from your computer. If you have two Wi-Fi networks, it’s possible that your computer is on one network while your printer is on the other. And if both networks are private, your computer won’t be able to tell your printer to print the picture.

Double NAT

This can also result in performance issues if you play online games or use port forwarding rules and UPnP.

Bridge mode fixes this by letting multiple routers share one single Wi-Fi network. Here’s what that could look like:

But Double NAT isn’t necessarily a problem. For most people, Double NAT does not affect Wi-Fi performance. But it can be an issue if you play online games or use IP address assignments, port forwarding rules, and UPnP. Learn more about Double NAT.
