- Large home / 4+ bedrooms: 4+ nodes

🧱 Why Thick Walls Need More Mesh Nodes

But in real UK homes:
- Brick walls block signal
- Concrete floors weaken upstairs coverage
- Chimney breasts and staircases create dead spots
That means extra nodes are often needed to keep speeds stable.

📍 Best Node Placement Tips
Understanding how many mesh nodes do you need for thick walls UK depends on your layout, number of floors, and how dense the internal walls are.
Do:
- Place one main node near your modem/router
- Put extra nodes halfway toward weak areas
- Keep nodes in open spaces where possible
Avoid:
- Hiding nodes in cupboards
- Placing nodes behind TVs
- Putting nodes directly behind thick walls
👉 Nodes need a good connection to each other.

📡 Does Wall Thickness Affect Every Mesh System?
Yes — even premium systems can lose performance if nodes are badly placed.
Thicker walls can:
- Reduce speed between nodes
- Create weak spots upstairs
- Lower performance in far rooms
👉 This is why placement matters just as much as buying the right system.
For best results, keep each node in a position where it still receives a strong signal from the previous node.
