Google Nest WiFi Pro Not Connecting Devices

Understanding the Issue

The Google Nest WiFi Pro is a tri-band Wi-Fi 6E mesh router system. When devices have trouble connecting or the network drops frequently, the issue usually relates to router placement, network configuration, interference, or ISP-level problems.

Common Causes

  • The mesh points are placed too far apart, creating dead zones
  • The modem or ISP gateway is not properly configured (double NAT)
  • Too many devices are connected to the network, causing congestion
  • Firmware needs updating
  • Interference from other wireless devices or neighboring networks
  • WPA3 security mode is incompatible with older devices
  • DNS settings are causing connection issues
  • The primary router's Ethernet connection to the modem is loose

Step 1: Check Physical Connections

  1. Verify the Ethernet cable between your modem and the Nest WiFi Pro's WAN port (globe icon) is securely connected at both ends.
  2. Check that the modem's indicator lights show an active internet connection.
  3. Ensure the power adapter is plugged in and the LED on the bottom of the Nest WiFi Pro is lit (pulsing white means booting, solid white means ready).
  4. If the LED is orange or red, there is a connectivity error. Restart the modem and router.

Step 2: Restart the Network

  1. In the Google Home app, go to WiFi > Settings and tap Restart network. This restarts all Nest WiFi Pro units in the mesh.
  2. If the app is not accessible, unplug the primary Nest WiFi Pro, wait 30 seconds, and plug it back in. Then do the same for each additional mesh point.
  3. Also restart your modem by unplugging it for 30 seconds and reconnecting.
  4. Wait five minutes for the full mesh network to come back online before testing connections.

Step 3: Improve Mesh Point Placement

  1. Each Nest WiFi Pro unit should ideally be within one to two rooms of the next unit, with no more than two walls between them.
  2. Place units in open areas, elevated on shelves or tables. Avoid floors, closets, cabinets, or behind large furniture.
  3. In the Google Home app, run a mesh test by going to WiFi > Devices and checking the connection quality for each point.
  4. If a mesh point shows a weak connection, move it closer to another unit and retest.
  5. For multi-story homes, place a mesh point on each floor, positioned centrally.

Step 4: Fix Device Connection Issues

  1. If specific devices cannot connect, check if they support Wi-Fi 6E (6 GHz band). Only newer devices support this band — older devices will connect via 2.4 GHz or 5 GHz automatically.
  2. If an older device fails to connect, check if WPA3 is enabled. Some older devices do not support WPA3. In the Google Home app, go to WiFi > Settings and enable WPA2/WPA3 compatibility mode.
  3. Try forgetting the Wi-Fi network on the problem device and reconnecting by entering the password again.
  4. If a device connects but has no internet access, check if Family Wi-Fi or parental controls are blocking that device's access.

Step 5: Check for Double NAT

  1. If your ISP provides a modem-router combo (gateway), it may be creating a double NAT situation that degrades performance and causes connectivity issues.
  2. Set your ISP gateway to bridge mode so it acts only as a modem, passing the public IP directly to the Nest WiFi Pro. Consult your ISP's documentation for bridge mode instructions.
  3. In the Google Home app, check the Nest WiFi Pro's WAN settings to see if it is reporting a double NAT warning.

Step 6: Check DNS and Internet Service

  1. In the Google Home app, go to WiFi > Settings > Advanced networking > DNS.
  2. By default, the Nest WiFi Pro uses Google's DNS (8.8.8.8 and 8.8.4.4). If you have custom DNS settings, try reverting to the default to rule out DNS issues.
  3. Run a speed test from the Google Home app to check your actual internet speed. If speeds are significantly below your ISP plan, contact your ISP.

Step 7: Factory Reset

  1. As a last resort, factory reset the Nest WiFi Pro. On the bottom of the unit, press and hold the reset button for about 10 seconds until the LED flashes.
  2. After the reset, set up the mesh network from scratch in the Google Home app.
  3. You will need to reconnect all devices to the new network.

Additional Tips

  • Each Nest WiFi Pro unit serves as a Thread border router, providing excellent support for Matter-compatible smart home devices.
  • The tri-band design includes a dedicated band for mesh backhaul communication, so adding more access points does not reduce user-facing Wi-Fi performance.
  • If you need a wired connection for a device like a gaming console or desktop computer, each Nest WiFi Pro unit has an Ethernet port on the back.
  • Firmware updates install automatically. Check the Google Home app for the current firmware version under WiFi > Settings > General.
