How to Fix Wi-Fi Dead Spots in Your Home or Office
Short answer
Dead spots happen when walls, distance and interference weaken the signal. Move the router to a central, open position first. If that fails, add access points connected by network cable (the most reliable fix) rather than relying only on repeaters, and choose clean channels and the right band for each area.
Quick fixes
- Place the router centrally, off the floor and away from metal and microwaves.
- Keep the router out of cupboards and away from thick walls.
- Restart and update the router firmware.
- Use the 5 GHz band for speed at close range and 2.4 GHz for longer reach.
- Check for interference from neighbours and change channels.
Real fixes
| Option | How it works | Verdict |
|---|---|---|
| Wired access points | Extra Wi-Fi units connected by cable to the router or switch | Best performance |
| Mesh with wired backhaul | Mesh nodes linked by cable | Very good |
| Wireless mesh | Nodes link to each other over Wi-Fi | Good for homes where cabling is hard |
| Range extender or repeater | Repeats the signal, halving throughput | Quick but limited |
| Powerline adapters | Use mains wiring for data | Works in some buildings |
For offices
Offices need a survey and several ceiling-mounted access points on PoE. See our office Wi-Fi guide and networking service.
Common questions
Why is my Wi-Fi slow upstairs?
Distance and floors weaken the signal. Add an access point on that floor, ideally wired.
Do Wi-Fi boosters work?
They help a little but cut speed. Wired access points work better.
Is a new router the answer?
Sometimes, but placement and extra access points usually matter more.
