- Try moving the router and checking settings before buying equipment.
- Extenders are cheap but can reduce speed, and mesh systems cover large homes better.
- Wired connections give the best results.
The short answer
A weak signal in the bedroom or the studio is one of the most common home internet complaints. Before you spend money, it helps to understand why the signal drops and to try the free fixes first. This guide goes through the options from cheapest to most reliable. For general set-up and security, read fast and secure home Wi-Fi network.
Why dead spots happen
- Distance: the signal weakens as you move away from the router.
- Walls and floors: concrete, metal and thick walls block signals.
- Interference: microwave ovens, cordless phones and neighbouring networks can disturb the signal.
- Old equipment: older routers and phones may be slower and weaker.
- Poor placement: routers hidden in cupboards or on the floor give a weaker signal.
Step 1: Free fixes
- Move the router to a central, higher position, in the open and away from thick walls.
- Restart the router and update its software.
- Use the 2.4 GHz band for longer range and the 5 GHz band for faster speeds at shorter range. Many routers offer both.
- Change the channel if neighbours use the same one. Many routers can do this automatically.
- Check that no one is using the network for heavy downloads at the same time.
- Replace very old routers.
Step 2: Wi-Fi extenders
A wireless extender, or repeater, picks up the existing signal and sends it again. It is cheap and easy to set up, but because it uses the same wireless link both ways, it can cut the speed in the extended area. Put it halfway between the router and the dead spot, where it still gets a good signal, not inside the dead spot itself.
Step 3: Mesh systems
A mesh system has several small units that work together as one network. Your devices move between units automatically. It suits larger homes and several floors. The units work best when connected to each other by cable, or with a strong wireless link. Mesh systems cost more than extenders but are easier to live with.
Step 4: Powerline adapters
Powerline adapters send the internet through your home’s electrical wiring. You plug one in near the router and another where you need coverage. Performance depends on the quality of the wiring and nearby electrical noise. They can help when walls block Wi-Fi, but results vary, and power problems can affect them. Plug them directly into the wall rather than into extension leads where possible.
Step 5: Wired access point
The most reliable solution is to run an Ethernet cable to a second access point or router placed in the far part of the house. It gives a strong, steady signal and does not reduce speed. If your home allows cabling, this is often the best long-term fix.
Comparison
| Option | Cost | Reliability | Best for |
|---|---|---|---|
| Move the router | Free | Good for small problems | Every home to start with |
| Extender | Low | Fair | One weak room |
| Powerline adapter | Low to medium | Varies | Rooms behind thick walls |
| Mesh system | Medium to high | Good | Large homes and several floors |
| Wired access point | Medium | Excellent | Studios and permanent set-ups |
Test and stay safe
- Test your speed in each room before and after the change, using a speed-test app.
- Keep the network protected with a strong password and up-to-date software.
- Remember that a slow internet plan is a different problem from a weak signal.
- Check your data plan if you rely on mobile data. See saving mobile data.
Quick checklist
- Move and restart the router first
- Use 2.4 and 5 GHz bands wisely
- Try an extender for one weak room
- Consider mesh for a large home
- Use cable for the best result
- Test speeds before and after
Key points to remember
Most dead spots can be fixed without buying anything, and the best solution is usually the simplest one that suits your home. If your devices are slow for other reasons, read how to speed up a slow laptop.
