Frequently Asked Questions

What distance should I maintain between Google WiFi points?
Google WiFi points should be placed 30-50 feet apart in most homes. In larger homes or those with thick walls, you may need to place them closer together, around 20-30 feet apart.
Why does my Google WiFi mesh test keep failing?
Mesh test failures are usually caused by WiFi points being too far apart, physical obstructions like walls or appliances between points, interference from other devices, or one of the points having a hardware issue.
Can I add more Google WiFi points to fix weak mesh connections?
Yes, adding additional WiFi points between existing ones can help bridge weak connections. However, ensure proper placement - more points doesn't always mean better performance if they're not positioned correctly.
How do I know if my Google WiFi point placement is optimal?
Use the mesh test in the Google Home app regularly. Optimal placement shows 'Great' connections between all points, provides consistent speeds throughout your home, and eliminates dead zones.
What should I do if only one Google WiFi point shows weak mesh connection?
Focus on repositioning that specific point closer to the main router or another strong point. Check for obstacles blocking its signal and ensure it's placed on an elevated, open surface away from interference sources.
