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. However, it can be an issue if you play online games or use IP address assignments, port forwarding rules, or Universal Plug and Play (UPnP).

Do Google Nest Wifi and Google Wifi support bridge mode?

Yes, but Bridge mode will only work if you’re using a single Wifi device. If you want to create a mesh network with multiple devices, your router or primary Wifi point cannot be in Bridge mode.

How do I enable bridge mode?

If you are only using a single device 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 to enable 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 Internet Service Providers (ISP) and manufacturers provide instructions on how to do this.

Enable bridge mode on your Google Nest Wifi router or primary Wifi point (Not recommended)

Note: Bridge mode will only work if you’re using a single Wifi device. If you want to create a mesh network with multiple devices, your router or primary Wifi point cannot be in Bridge mode.

While all additional devices are always in bridge mode by default, we don’t recommend to turn your router or primary Wifi point into a bridge. This is because the router or primary Wifi point needs 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 will be unavailable
  • Wi-Fi speed results in Network check will be unavailable (But download and upload results will still work.)
  • Philips Hue pairing and controls

Additionally, bridge mode disables many of Google Nest Wifi and 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, and other security functions.

Google Nest Wifi and Google Wifi’s automatic security updates maximize your privacy and security. Their protective features are most effective, and in some cases, only effective when all traffic passes through your router or primary Wifi point (instead of another router).

If you have a third party router, you can wire a Google Nest router or primary Wifi point to it, then “mesh” additional Wifi devices downstream. Learn how to connect your Google Nest Wifi to a third party router.

Still want to turn your Nest Wifi router or primary Wifi point into a bridge? Here’s how:

With the Google Home app

Note: This feature will roll out over the next few days.

  1. Open the Google Home app Google Home app.
  2. Tap Wifi  and then Settings  and then Advanced Networking.
  3.  Tap Network mode and then your Wifi router or point and then Bridge mode.

With the Google Wifi app

  1. Open the Google Wifi app .
  2. Tap Settings and actions tab  and then Network & general.
  3. Tap Advanced networking and then Network mode and then your Wifi point and then Bridge mode.
  4. Tap Save.

Note: You cannot transition your router or 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 router or primary Wifi point. If your router or 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.

When do I need Bridge mode?

If you connect two routers, it 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.

To fix this, Bridge mode lets multiple routers share one single Wi-Fi network. Here’s what that could look like:

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.
