Router Placement Guide
Where you put your router has a bigger impact on Wi-Fi performance than most people realize. Follow these rules to get the strongest signal throughout your home.
The 7 golden rules of router placement
How building materials affect Wi-Fi signal
| Material | Signal Loss | Notes |
|---|---|---|
| Open air | Minimal | Baseline. No barrier. |
| Drywall / Plasterboard | Minor (3-5 dB) | Standard interior walls. Most modern homes. |
| Wood door or furniture | Minor (3-5 dB) | Low density material. Little impact. |
| Plaster wall (older homes) | Moderate (5-8 dB) | Older construction. Noticeable degradation. |
| Brick wall | Significant (10-15 dB) | Common in older homes and commercial buildings. |
| Concrete wall or floor | Heavy (15-25 dB) | Can block most signal over a few meters. |
| Metal objects | Severe / Reflective | Reflects signal rather than absorbing it. Creates interference patterns. |
| Water (fish tank, pipes) | Significant (10-15 dB) | Water absorbs 2.4 GHz signals strongly. |
Best placement by room type
Where to place your router: a visual guide
Central position covers all rooms equally.
Corner position leaves far rooms with poor signal.
Wi-Fi extenders and mesh systems
If your home is large, has multiple floors, or has thick walls that block signal, a single router may not be enough. Two options exist: Wi-Fi extenders (also called repeaters) and mesh systems.
A Wi-Fi extender receives your router's signal and rebroadcasts it from a location closer to the weak area. They are inexpensive and easy to set up, but they typically cut network throughput in half because they use one radio to both receive from the router and broadcast to devices. Devices also do not always switch cleanly between the router and extender as you move around the house, which can cause brief connection drops.
A mesh system uses two or more nodes that communicate with each other over a dedicated backhaul link or a separate radio band. Your devices see a single network name and automatically connect to the nearest node as you move around. Mesh systems provide much more consistent coverage than extenders and maintain higher throughput. They cost more but are the better choice for homes where a single router cannot cover the entire space.
Use an extender if you have one or two dead spots in an otherwise well-covered home and want a low-cost fix. Upgrade to mesh if you need reliable coverage across a large space, multiple floors, or a home with dense construction materials.
Wi-Fi troubleshooting checklist
- Restart your router. Unplug it, wait 30 seconds, and plug it back in. This clears cached connections and often resolves temporary slowdowns.
- Move the router to a more central position. Even moving it a few feet away from a corner can noticeably improve coverage in the opposite direction.
- Remove the router from enclosed furniture. If it is inside a media cabinet, place it on top instead.
- Switch to the 5 GHz band for nearby devices. If your device is within 20 feet of the router, the 5 GHz band is faster and less congested than 2.4 GHz.
- Update router firmware. Log in to your router's admin panel and check for firmware updates. Outdated firmware can cause instability.
- Change the Wi-Fi channel. If neighbors are using the same channel, you may see interference. Most routers have an "auto" channel setting that helps, but manually selecting a less congested channel can improve speeds.
- Check for interference sources nearby. Move the router away from microwaves, cordless phones, baby monitors, and Bluetooth devices.
- Test with a wired Ethernet connection. If speeds are good on Ethernet but poor on Wi-Fi, the problem is confirmed to be the wireless side. Consider a Wi-Fi 6 router upgrade if your current model is more than 4 years old.
Common questions about router placement
A closet placement significantly reduces Wi-Fi coverage because the walls block the signal in multiple directions. If the closet is central and has thin drywall walls, you may retain acceptable coverage. A solid wood or hollow-core door reduces signal less than a wall. If aesthetics are the concern, a small shelf in an open area is a better compromise.
Yes. Wi-Fi signal travels better horizontally than vertically. For a two-story home, placing the router on the first floor near the center provides the best coverage on both floors. For a three-story home, the second floor is the best choice. Placing it in a basement or attic is almost never the right answer unless devices are concentrated there.
In open air with no obstructions, Wi-Fi can reach 100-150 feet (30-45 meters) for the 2.4 GHz band and 50-75 feet (15-23 meters) for the 5 GHz band. In a typical home with walls, these distances are considerably shorter. Concrete, brick, and metal reduce range significantly. Most homes benefit from a router placement that keeps devices within 30-50 feet of the router through as few walls as possible.
No. Your internet plan speed and your Wi-Fi range are separate things. Wi-Fi range is determined by your router's hardware and placement, not by the speed of the internet plan you pay for. A faster plan does not extend your Wi-Fi signal further.
