FAQ
Q: What makes mesh Wi-Fi better than a traditional router for concrete walls?
A: Mesh Wi-Fi systems use multiple nodes to create a wider and more reliable network. These nodes communicate with each other, providing better signal penetration through obstacles like concrete walls, eliminating dead zones.
Q: How many mesh points do I need for my home?
A: The number of points depends on the size of your home, the thickness of your walls, and the number of devices you need to connect. Start with a 3-pack for most homes, and add more as needed.
Q: Do all mesh Wi-Fi systems work equally well with concrete walls?
A: No. While many mesh systems offer improved performance compared to traditional routers, some are better equipped to handle concrete walls than others. Look for systems with features like Wi-Fi 6 or Wi-Fi 7 and higher transmit power.
Q: Will mesh Wi-Fi eliminate all dead zones?
A: While mesh Wi-Fi dramatically improves coverage and reduces dead zones, it might not eliminate them completely in homes with exceptionally thick concrete walls or complex layouts.
Q: Can I mix and match mesh points from different brands?
A: Generally, it’s not recommended. Mixing brands can lead to compatibility issues and reduce overall performance. Stick with a single brand for optimal results.
Q: What is backhaul, and why is it important for concrete walls?
A: Backhaul refers to how the mesh points communicate with each other. Wired backhaul (Ethernet cables) offers the best performance and is especially helpful in homes with thick walls, while wireless backhaul is convenient but can be affected by interference.
Q: What are some other factors to consider when choosing a mesh Wi-Fi system for concrete walls?
A: Consider the size of your home, the number of devices you’ll connect, your internet speed, your budget, and the features you need (parental controls, guest networks, etc.).
