How Walls Affect WiFi Signals?

What is a WiFi signal and how does it work?

The internet can be accessed via a wifi signal, which is a wireless network. It works by transmitting data between a router and your devices, such as smartphones, laptops, and tablets. The strength of the wifi signal is measured in decibels (dB) and the higher the dB, the stronger the signal.

How do walls affect WiFi signals?

The strength of your WiFi signal can be greatly affected by the walls around your house. There is a direct correlation between the thicker and more solid the walls are, the more they will block and weaken the signal. This means that WiFi signals have a harder time passing through walls made of brick, concrete, or metal. However, it’s imperative to note that different types of walls will affect the signal differently.

How To Boost Your Wifi Signal Through the Walls with Equipment

Router placement

One of the easiest ways to improve your wifi signal through walls is by placing your router in the right spot. The ideal location is in a central location in your home, with minimal walls and obstructions between it and the areas where you use your devices the most. If you place your router in a corner or behind a large object, the signal will be weakened, so it is best to avoid such places.

Wifi extenders

Another option to boost your wifi signal through walls is by using wifi extenders. A Wi-Fi extender is a device that is used for amplifying and extending the range of your Wi-Fi signal in order to obtain a better signal quality. Simply place the extender in an area with a strong wifi signal, such as near a window, and it will repeat the signal to the areas of your home where the signal is weak.

DIY Solutions to Boost Your Wifi Signal Through Walls

Aluminium foil

Believe it or not, something as simple as aluminum foil can boost your wifi signal. This method involves placing aluminum foil behind your router to reflect the signal and improve its reach.

DIY Antennas

If you’re feeling handy, you can try building your own wifi antennas to improve your signal. There are many tutorials available online that will guide you on how to build a DIY wifi antenna using materials such as PVC pipe and tin foil.

Other Tips and Tricks to Boost Your Wifi Signal

Updating your router’s firmware

Updating your router’s firmware can improve its performance and boost your WiFi signal. On the manufacturer’s website, you will be able to find information about the latest firmware updates and instructions on how to install them.

Changing your wifi channel

If you live in a densely populated area, there may be a lot of other wifi signals competing for the same frequency. If you are looking for a way to improve the signal strength of your Wi-Fi network and reduce interference, change your Wi-Fi channel.

Troubleshooting Tips on How to Boost WiFi Signal Through Walls

  • Check the Router’s Position:

One of the first things to check when troubleshooting weak WiFi signals is the position of your router. Make sure it’s in a central location and not hidden behind large objects or walls.

  • Check for Interference:

Another common cause of weak WiFi signals is interference from other devices. This can include anything from microwaves and cordless phones to baby monitors and even certain types of lighting. Turn off other devices or move your router to a more convenient location to see if this helps.

  • Update Firmware:

It is imperative that you are running the most up-to-date firmware on your router. In addition to improving performance and fixing bugs, manufacturers often release updates.

  • Check the Channel:

WiFi routers typically have multiple channels to choose from. Your connection may be slowed down if you set your router to a channel with a lot of other devices on it. It may be a good idea to try changing the channel to see if this improves the signal quality.

  • Check the Antenna:

If you are using a router that has an external antenna, make sure it is properly positioned. Sometimes, a simple adjustment to the antenna can have a huge impact on the strength of the signal as a whole.

  • Reset the Router:

Sometimes, a simple reset can fix a variety of problems. It might be a smart strategy just to unplug the router for a few minutes and then plug it back in.

  • Consider a WiFi Extender:

In the event that none of the above solutions are successful, you might want to consider buying a WiFi extender. These devices can help boost the signal and reach areas of your home that were previously out of range.

  • Hire a Professional:

If all else fails, you may want to consider hiring a professional to assess your home’s WiFi setup and make recommendations. They can help identify any structural issues that may be causing weak signals and provide solutions to improve coverage.

Additional Tips on How To Boost WiFi Signal Through The Walls

  • Place Your Router in the Right Spot:

The location of your router can greatly impact the strength and reach of your WiFi signal. The best place for your router in your home is in a central location, away from walls and other obstructions that can cause the signal to be weak or blocked.

  • Use a WiFi Range Extender:

WiFi range extenders are useful if your router’s signal is not reaching certain parts of your home. In areas of your house with weak signals, it is possible to use these devices to amplify the signal from your router in those areas.

  • Change the Channel on Your Router:

WiFi routers broadcast on different channels, and in some cases, your router may be competing with other devices on the same channel. It is possible to improve your signal and prevent interference from other devices by changing the channel on your router.

  • Use a High-Gain Antenna:

Some routers come with a built-in high-gain antenna that can improve the signal strength and reach. Should your router not have one, you can buy one separately and attach it to your router.

  • Update Your Router’s Firmware:

You may experience slow connections and weak signals if the firmware of your router is outdated. You can improve your router’s performance by updating its firmware and boost your WiFi signal through the walls.

  • Try a Powerline Adapter:

If your router is on one end of your home and you’re having trouble getting a signal in other areas, a powerline adapter can help. By using your home’s electrical wiring, this device extends your network to other rooms.

  • Reduce Interference:

Your WiFi signal can be interfered with by electronic devices such as microwaves, cordless phones, and baby monitors. Try to keep these devices away from your router and other wireless devices to reduce interference.

  • Optimize Your Device Settings:

Many devices, such as smartphones, tablets, and laptops, have settings that can help improve your WiFi signal. For example, enabling “airplane mode” on your device can help improve your signal when you’re in a weak coverage area.


As a result, boosting your WiFi signal through walls may seem challenging, but with the aid of certain tools and strategies, it’s definitely doable. Whether you choose to use a WiFi extender, a mesh network system, or other methods, make sure to do your research and find the best solution for your specific needs. Remember to always check for interference, optimize your router placement, and consider professional installation if necessary. With a little practice, you can enjoy a stronger and longer consistent WiFi signal throughout your entire home. Don’t forget to follow all the tips and troubleshooting methods mentioned in the article for an optimal result. Happy surfing!
