How to fix Wi-Fi dead zones at home
Wi-Fi that works in the living room and dies in the bedroom is usually not a problem with your internet plan. Walls, floors, distance and where the router sits decide coverage. Before buying anything, map where the signal is weak. Often moving the router is enough, and if not, you will know exactly where extra hardware needs to go.
A practical routine, then Wi-Fi heatmap apps, with a section for Wi-Fi apps rising by visits on the Censuus ranking.

Map before you buy
Walk through your home with a Wi-Fi heatmap app, ideally on a floor plan, and note where the signal drops. Weak zones usually follow thick walls, floors, long distances or rooms at the far end of the house. The map shows whether the problem is one room or half the home.
Put the router in the right place
A router in a cupboard, on the floor or behind the TV covers far less than one placed centrally, high up and in the open. Keep it away from metal objects, large mirrors, fish tanks and microwaves. Point any external antennas in different directions.
Update and check settings
Update the router’s firmware and restart it. If your router has separate bands, devices far away may hold a steadier connection on the longer-range band. Many neighbours’ networks on the same channel can slow things down, which some routers fix automatically.
Add hardware where the map says
If moving the router is not enough, a mesh system or extender placed between the router and the weak zone fills the gap. Run the heatmap again afterwards to check. Compare apps in Wi-Fi heatmap apps.
| Step | What you do | Why |
|---|---|---|
| 1. Map the signal | walk room by room with a heatmap app | see where it is weak |
| 2. Move the router | central, high, in the open | better coverage for free |
| 3. Reduce interference | away from metal, mirrors, microwaves | cleaner signal |
| 4. Update and restart | router firmware and settings | fixes bugs and slowdowns |
| 5. Add hardware last | mesh or extender where the map shows gaps | money spent in the right place |
Frequently asked questions
How do I find Wi-Fi dead zones at home?
Walk through your home with a Wi-Fi heatmap app, ideally on a floor plan, and note where the signal drops.
How can I improve Wi-Fi without buying anything?
Move the router to a central, high, open spot away from metal and microwaves, update its firmware and restart it.
Mesh or extender: which do I need?
Map your signal first. A single weak room may only need an extender; weak zones across a large home often suit a mesh system.
