For optimal mesh router placement, position the main unit centrally and elevated, away from obstructions (metal, concrete, large appliances) and interference (microwaves, cordless phones). Place wi-fi mesh nodes roughly halfway between the main router and dead zones, ensuring good line-of-sight to other nodes and devices, but avoid placing them too close together to prevent congestion.
Test coverage and adjust nodes as needed for seamless, strong Wi-Fi throughout your home.
