Key takeaways
- Place the router centrally, up high and in the open, away from thick walls, metal and appliances.
- Restarting the router and installing firmware updates can fix many slowdowns.
- The 5 GHz and 6 GHz bands are faster at short range; 2.4 GHz reaches farther but is slower and more crowded.
- Mesh Wi-Fi systems or extenders help in larger homes and multi-story houses.
- Use a wired Ethernet connection for devices that stay put, like TVs, consoles and desktop computers.
A fast internet plan doesn’t help if the Wi-Fi signal can’t reach the rooms where you use it. These fixes are listed roughly from free and easy to more involved.
1. Move the router
Wi-Fi signals weaken with distance and obstacles. For better coverage:
- Central: put the router near the middle of your home, not in a corner or the basement.
- High: place it on a shelf rather than the floor.
- In the open: don’t hide it in a cabinet or behind the TV.
- Away from interference: keep it clear of thick walls, metal objects, mirrors, microwaves and cordless phone bases.
2. Restart and update
Restart the router and modem if speeds drop. Then check for firmware updates in the router’s app or settings page. Updates can improve performance and fix security problems; our guide to securing your home Wi-Fi explains why they matter.
3. Use the right band
Most routers broadcast on more than one frequency band:
| Band | Strengths | Trade-offs |
|---|---|---|
| 2.4 GHz | Longer range, better through walls | Slower, more crowded |
| 5 GHz | Faster, less crowded | Shorter range |
| 6 GHz (on newer equipment) | Fastest, least crowded | Shortest range, needs compatible devices |
Many routers combine bands under one network name and steer devices automatically. If yours doesn’t, connect nearby devices to 5 GHz or 6 GHz.
4. Reduce the load
- Pause large downloads and cloud backups during video calls.
- Disconnect devices you no longer use.
- Check whether streaming quality settings are higher than you need on small screens.
Quick tip: Run a speed test right next to the router, then in a room where Wi-Fi is weak. A big difference points to a coverage problem rather than a slow plan.
5. Extend coverage
- Mesh Wi-Fi systems use several units placed around the home to create one seamless network. They suit larger homes and multi-story houses.
- Wi-Fi extenders are cheaper and repeat the signal, but can cut speeds.
- Powerline adapters carry data through your home’s electrical wiring and can help where Wi-Fi struggles.
6. Go wired where you can
For devices that don’t move, such as smart TVs, game consoles and desktop computers, an Ethernet cable usually gives the fastest, most stable connection. It also frees up Wi-Fi for phones and laptops.
7. Talk to your provider
If speeds are slow even with a wired connection, contact your provider. Check what your plan’s broadband label lists as typical speeds; our guide to broadband labels explains them, and our speed guide helps you judge whether your plan is a good fit.
FAQ
Should I rent or buy my router?
Renting is convenient and the provider usually handles updates, but monthly fees add up. Buying can save money over time if the router is compatible with your provider. Check the broadband label for equipment fees.
Mesh system or Wi-Fi extender?
Mesh systems use several units that work together as one network, which generally gives smoother coverage across a large home. Extenders are cheaper but can reduce speed and may create a separate network name.
How often should I restart my router?
There’s no fixed rule. Restarting is a good first step when things slow down, and many routers restart themselves after installing updates.
Can neighbors’ Wi-Fi slow mine down?
In crowded areas like apartment buildings, nearby networks can cause interference, especially on 2.4 GHz. Using 5 GHz or 6 GHz, or letting the router choose channels automatically, can help.
