WiFi dead spots almost never have anything to do with your broadband speed. The cause is almost always physical — walls, floors, the distance between your router and the devices that need it most. The solution is either a correctly placed access point or a mesh system with nodes positioned to eliminate the specific dead zone, not just placed wherever is convenient.

• Whole-home WiFi signal survey — signal mapping room by room with a professional tool
• Router position assessment and relocation recommendation where needed
• Mesh node positioning, installation and configuration for seamless roaming
• Wired backhaul installation where structurally practical (this doubles mesh performance)
• Network SSID and band steering configuration
• Speed test and signal strength verification in every room after completion
