WiFi Extenders for a Garden Office: What Works

A WiFi extender for a garden office must be placed where the main router still provides a usable signal; putting it inside a disconnected outbuilding will not create a backhaul. Measure signal at the house wall and office, and consider the structure and route between them. If Ethernet can be run safely, an access point at the office gives a wired backhaul. Powerline uses the home electrical wiring and depends on the outlets being on the same circuit, so a detached building may not suit it. For a wireless bridge, assess line of sight and use hardware intended for the installation environment.
