Where to place a Wi-Fi router and mesh nodes in a UK home

Start with an open practical router position and put a wireless satellite where it can still reach upstream. Test the device you use in the room, then move one node at a time. A satellite placed in the deepest dead spot inherits the same difficult radio path.
Establish the baseline
Use the same PC or phone, task and location for the comparison. Test beside the router, in the problem room and through a supported wired connection where available. That separates weak coverage from an internet or device issue.
Mark the main unit, intended desks and major obstructions on a simple floor plan. Note solid walls, floors and large metal objects. Avoid a promise based only on floor area; houses with the same size can present very different radio paths.
Improve the main position
Keep the router in an open position with ventilation, away from a metal enclosure or a crowded floor-level corner. Follow the model’s antenna-position guidance. A long supported Ethernet route can sometimes move the Wi-Fi unit to a more useful location without moving the provider’s handoff.
Keep cables and power arranged securely, and preserve access for supported maintenance. The neatest-looking cabinet is not always the best radio position. For a fixed desk nearby, Ethernet can remove that PC from the coverage problem.
Place the satellite for both sides of its job
A useful signal from the existing network
Open position between coverage zones
Useful connection in the target room
Same task, device and location after each move
Start between the main coverage area and the weak room, then use the mesh system’s supported placement guidance and actual client results. Move one unit at a time so the effect is understandable.
Use Ethernet backhaul when a practical cable route exists. The satellite can then serve a useful room without relying on the same difficult wireless path to the main unit. The layout guide compares that with wired APs.
Choose additional hardware after the layout check
If positioning cannot serve the room, choose a suitable mesh system or a wired access point around the available backhaul. Adding more nodes indiscriminately can complicate the layout rather than solving it.
For a detached outbuilding, use an installation designed for that environment and link route; an indoor router pushed against a window is not a complete outdoor-network plan. For the house itself, the Ethernet installation guide helps plan useful cable runs.
