Hardwire Nest Wifi Pro, Nest Wifi, or Google Wifi with Ethernet

Nest Wifi Pro, Nest Wifi routers, and Google Wifi are Wi-Fi systems that are typically connected wirelessly. However, if you prefer wired backhaul, these devices have Ethernet ports that let you physically connect them together. Here are some possible setups you can do:

• Chain multiple routers together
• Connect devices like a computer or TV directly into the LAN port of your router
  Note: For a mesh point, either the WAN or LAN port can be used as a LAN port. Use a switch to add more LAN ports to hardwire your Wifi devices.
• Use third-party routers in addition to your Nest or Google Wifi network

Things to avoid:

• Don't connect any devices including computers, switches, or another Wifi point to your primary Wifi device that's plugged into your modem, until after setup is completed.
• Nest Wifi points don't have Ethernet ports and can't be hardwired.
• Nest Wifi Pro (Wi-Fi 6E) can't be combined with Nest Wifi or Google Wifi (Wi-Fi 5) in a mesh network. 
• Don't include more than 5 routers or points in a mesh network. Adding more might be detrimental to Wi-Fi performance.

• If you use a switch, we recommend using an unmanaged switch or configuring a managed switch to disable Spanning Tree Protocol (STP) and forward Bridge Protocol Data Units (BPDUs) when STP is disabled.  This will avoid technical issues with some managed switches as it relates to routing and network loops.

Key terms for hardwiring your network

The supported setups below use the following terms:

• Wifi router: Commonly refers to the Nest Wifi Pro, Nest Wifi, or Google Wifi device that's connected to the modem. Router is also used for Wifi devices that have Ethernet ports.
• Point: A point or points refer to any Nest Wifi Pro, Nest Wifi, or Google Wifi device that's added to the main router as part of your mesh network to extend coverage. Nest Wifi points don't have Ethernet ports and can't be hardwired. Learn more about compatibility for Nest Wifi and Google Wifi products.
• Switch: A switch is a networking device that connects devices, like computers, printers, and services, to each other, typically over Ethernet ports. Having a switch can allow you to expand your networking system with additional Ethernet ports, which enables you to hardwire more devices to your network. If you use a switch, we recommend using an unmanaged switch or configuring a managed switch to disable Spanning Tree Protocol (STP) and forward Bridge Protocol Data Units (BPDUs) when STP is disabled.  This will avoid technical issues with some managed switches as it relates to routing and network loops.
• Third-party router: This refers to a router provided by your ISP (Internet Service Provider) or one you own that isn't a Nest Wifi or Google Wifi product. In some cases, rather than using a switch, you can use an old router to provide additional ports to your network. Before you use your old Wi-Fi router as a switch, turn off any built-in Wi-Fi in the third-party router.
• Ethernet cable: To hardwire your devices, you'll need to connect each device together with Ethernet cables. It's recommended you use a minimum of CAT5e-rated cables for Nest Wifi Pro, Nest Wifi, and Google Wifi.
• WAN port : This is the outbound port that connects your main router to the internet. It's wired toward your modem.
• LAN port : This is the inbound port that goes toward your wired devices.

Supported setups

Use multiple Nest Wifi routers or Google Wifi points

Note: In the following diagrams, "→" means to connect via wired Ethernet. Refer above for the list of terms.

(✓) Modem → Wifi router → Point

1. Modem's LAN port connects to Wifi router's WAN port  over wired Ethernet.
2. Wifi router's LAN port connects to a point's WAN port over wired Ethernet.

You can chain multiple points over wired Ethernet.

(✓) Modem → Wifi router → Point → Additional point → and so on

Include a switch downstream of the Wifi router

Learn more about using switches with Google Nest Wifi or Google Wifi devices. 

Note: In the following diagrams, "→" means to connect via wired Ethernet. Refer above for the list of terms.

(✓) Modem → Wifi router→ Switch → Point(s)

1. Modem's LAN port connects to Wifi router's WAN port  over wired Ethernet.
2. Wifi router's LAN port connects to switch's WAN or uplink port over wired Ethernet.
3. Switch's LAN port(s) connects to any point's LAN port over wired Ethernet.

Switches and points can be connected in any order, as long as they're downstream of the Wifi router, and you can connect several of these devices over wired Ethernet. It's important to connect downstream as it allows the Wifi router to manage the downstream points over the wired Ethernet.

Note: Don't connect points that aren't set up yet to a switch. Only connect your points to a switch once they're ready for setup.

(✓) Modem → Wifi router → Point → Switch → Point → Additional point

Include a third-party router upstream of the primary Wifi point (not recommended)

Tip: Instead of buying a new switch, it might be possible to use a third-party router as a switch. To do this, set the third-party router in bridge mode and disable its Wi-Fi functions. Refer to the third-party router manual on how to do this. 

Note: In the following diagrams, "→" means to connect via wired Ethernet. Refer above for the list of terms.

(✓) Modem → Third-party router → Wifi router → Point

1. Modem's LAN port connects to third-party router's WAN port over wired Ethernet.
2. Third-party router's LAN port connects to Wifi router's WAN port over wired Ethernet.
3. Wifi router's LAN port connects to any point's WAN port over wired Ethernet, or a switch as shown above.

With this configuration, you might run into Double NAT, which isn't necessarily a problem. But if it's causing problems, it's recommended you put your third-party router in bridge mode. Once in bridge mode, you can choose whether or not to turn Wi-Fi off on your third-party router.

Setups to avoid

Wire a Wifi router to other points in the same switch

Note: In the following diagrams, "→" means to connect via wired Ethernet. Refer above for the list of terms.

(X) Modem → Switch → Wifi router

                                        → Point

(X) Modem → Third-party router → Switch → Wifi router

                                                                                 → Point

1. Modem's LAN port connects to switch's WAN or uplink port over wired Ethernet.
2. Switch's LAN ports connect to both a Wifi router and another point.

To work as a mesh point, the point should always be wired downstream from the Wifi router. In the diagrams above, the mesh won't work is because the point is unable to get an IP address from the Wifi router. Rather, both the Wifi router and point get IP addresses from the upstream modem, so the Wifi router isn't able to form the mesh with the Wifi point.

For correct operation, the Wifi router should either be plugged in between the modem and switch, or the point should be plugged in downstream of the Wifi router.

Wire Wifi routers or points into the same third-party router

Note: In the following diagrams, "→" means to connect via wired Ethernet. Refer above for the list of terms.

(X) Modem → Third-party router → Wifi router

                                                              → Point

1. Modem's LAN port connects to third-party router's WAN port over wired Ethernet.

2. Third-party router's LAN ports connect to both a Wifi router and another point's WAN ports over wired Ethernet.

In this example, the point should be plugged in downstream of the Wifi router instead.

(✓) Modem → Third-party router → Wifi router → Point

Wire a third-party router downstream of the Wifi router

Note: In the following diagrams, "→" means to connect via wired Ethernet. Refer above for the list of terms.

(X) Modem → Wifi router → Third-party router → Point

1. Modem's LAN port connects to Wifi router's WAN port over wired Ethernet.
2. Wifi router's LAN port connects to third-party router's WAN port over wired Ethernet.
3. Third-party router's LAN port connects to Google Wifi point's WAN port over wired Ethernet.

If the third-party router isn't in bridge mode (NAT is still active), any wired or wireless clients including the mesh points might not be able to communicate with the Wifi router as the third-party router NAT will create a separate subnet.

To work as desired, the third-party router should be set to bridge mode, replaced with a switch, or removed from the network.
