Smart Home Troubleshooting Guides & Device Fixes

A smart-home problem can begin in several places: the WiFi network, a voice assistant, or the connection between an app and a device. Start with the guide that best matches what you are seeing, then follow the checks for that specific issue.

Start with the type of problem

WiFi and connectivity

Use this section if a smart device will not connect, keeps going offline, responds slowly, or stopped working after a router or network change.

Browse the complete smart-home WiFi troubleshooting guide to find the right topic, including coverage, setup, disconnects, router issues, mesh WiFi, and band compatibility.

Alexa and Google Assistant

Choose this section if a speaker does not respond, misunderstands a request, reports an error, or cannot control a connected device.

Browse the voice-assistant troubleshooting guide to narrow the issue down before changing device or network settings.

Common WiFi problems

How to use these guides

Before changing settings, note whether the problem affects one device or several, whether it happens in one room or throughout the home, and whether anything changed just before it started. Those details can help you choose a more relevant fix and avoid changing several things at once.

Each guide focuses on a specific symptom. Follow its checks in order and test the original problem again after making a change. If the first guide does not match what is happening, return here and choose a different symptom.
