So your Google Home isn’t connecting to a new Wi-Fi network — it’s frustrating, especially if you’re trying to set things up after moving or switching routers. The good news is, most of the time it's not a hardware issue. It’s usually something in the setup process or network compatibility that’s throwing it off.

Let’s go over what typically causes this and how to fix it.

Check Basic Requirements First

Before diving into complex troubleshooting, make sure the basics are covered:

• Google Home app is updated – Outdated apps can cause connection issues.
• Same Wi-Fi network on your phone – Your phone needs to be connected to the same network you're trying to connect your Google Home to.
• 2.4 GHz network only – Google Home devices (like the original Google Home, Nest Mini, etc.) don't support 5 GHz networks. If your router is dual-band, make sure you're selecting the 2.4 GHz option.
• No special characters in Wi-Fi name/password – Some symbols like “#” or “%” can mess with the device’s ability to connect.

If any of these points aren’t met, adjust them first before moving on.

Reset and Reconfigure the Device

Sometimes just resetting the device helps when changing networks.

To reset:

• Press and hold the button on the side or bottom of your Google Home for about 10 seconds until the light turns red.
• Open the Google Home app and remove the device from your list.
• Then go through the setup process again as if it’s a brand-new device.

Make sure during setup that you select the correct Wi-Fi network. This often resolves mismatched credentials or outdated settings lingering from the old network.

Router Settings That Might Be Blocking It

Even if everything looks good on the Google Home side, some router settings can interfere:

• MAC address filtering – If enabled, your Google Home might be blocked unless its MAC address is specifically allowed.
• Firewall or parental control features – Some advanced routers block certain types of smart home devices by default.
• Hidden SSID – Don’t try to connect your Google Home to a hidden network; it won’t work properly.
• Channel width on 2.4 GHz – Some routers use wide channels that older smart devices struggle with. Try setting the 2.4 GHz channel width to 20 MHz instead of auto or 40 MHz.

You can usually find these settings in your router’s admin panel, which you can access via a web browser using the router’s IP address (often something like 192.168.0.1 or 192.168.1.1).

Try a Temporary Network Fix: Use a Mobile Hotspot

If you’re still stuck and want to test whether the issue is with your main router, try connecting your Google Home to a mobile hotspot.

This gives you a clean, simple network to test on. If it connects there, you know the problem is likely with your home router settings, not the Google Home itself.

That’s basically it. Most people get their Google Home working again by double-checking the Wi-Fi band, resetting the device, and ensuring the router isn’t blocking it. It’s not complicated, but there are enough little details that it can trip you up if you miss one.
