How to Boost WiFi Signal Through Walls

Have you encountered WiFi internet connection lagging

Imagine that you are working in your study room, and the WiFi signal just goes up and down because your router is far away in another room. As a result, you can't finish your task as expected and may get blamed by your leader.

I've been there, too.

Fortunately, I spent some time researching how to boost the WiFi signal through walls and came up with 4 quick solutions.

Keep on reading, and I will lift this veil for you.

Apply WiFi 6 Technology

The first solution to boost WiFi signal is by applying WiFi 6 technology, which was put on the market last year! If you want to use WiFi 6, the first thing you should do is to buy a new WiFi 6 router. Because WiFi generations rely on new hardware, not just software updates like games, you'd better purchase new phones and laptops to get the latest version of WiFi. WiFi 6 is backward compatible with older WiFi standards so that it can be used with existing user devices. However, to maximize the effect of boosting WiFi signal through walls, newer devices designed for the standard are required.

What is WiFi 6?

WiFi 6 is the newest generation of WiFi technology, designed to provide faster speeds and greater capacity than ever before. WiFi 6 is based on the 802.11ax standard and uses many new features to improve performance. Accordingly, WiFi 6 can be good at boosting WiFi signal through walls.

Why Recommend Using WiFi 6?

9.6 Gbps is the maximum throughput of WiFi 6, but theoretically, WiFi 5 offers a maximum of 6.93 Gbps. Therefore, boosting WiFi signal through walls is a small case as for WiFi 6.

WiFi 6 has the feature of OFDMA, which stands for Orthogonal Frequency Division Multiple Access. This is a new technology that helps to reduce contention and improve speeds.

WiFi 6 also uses a large number of sub-carriers than previous WiFi standards. This allows for more data to be transmitted simultaneously, further increasing speeds.

Finally, WiFi 6 uses MU-MIMO to allow multiple devices to be connected at the same time without sacrificing performance.

These new features combine to make WiFi 6 the fastest and most capable WiFi standard yet. If you need speed, then WiFi 6 is the way to go.

The Benefits of WiFi 6

Use a Mesh WiFi System

The second solution to boost WiFi signal is by using a mesh WiFi system. A mesh WiFi system is a type of network that uses multiple wireless routers to extend the coverage area of a wireless network. By using various routers, a mesh network can provide better coverage than a single router and can be configured to provide redundancy in case of failure.

Installing a mesh network can be a bit more complicated than installing a traditional wireless network, but it is still relatively easy. 

1. Determine the coverage area. Purchase the appropriate number of routers according to your desired WiFi coverage. 

2. Configure the routers. This can be done using the router's web-based interface or a mobile app. 

3. Connect the routers. This can be done using Ethernet cables or by using wireless bridges. 

4. Secure the network. The final step is setting up a password for the web or using encryption to secure the network.

Choose a Proper WiFi Extender

Choosing a powerful WiFi extender is the easiest way to boost WiFi signal through walls. WiFi extenders are dedicated to strengthening WiFi signals and eliminating dead spots and dropouts in the WiFi coverage area. Furthermore, setting up a WiFi extender is rather simple; just establish it on your WiFi router, it works in a manner that helps your routers work better. 

Equally important, you should check whether the WiFi extender is compatible with your home router when buying one; some WiFi extenders can only be compatible with certain routers. Fortunately, there are WiFi extenders adapting to all kinds of routers in the market, they are excellent choices. A friendly suggestion-with the newest version of the WiFi generation (WiFi 6) coming out, choosing a WiFi extender with WiFi 6 technology does better in strengthening the signal through walls.

Choose a Proper WiFi Booster

Connect High-Gain External Antennas

If you want to get the most out of your wireless router and boost WiFi signal through walls, take a high-gain external antenna into consideration.

One of the most popular uses for high-gain antennas is to extend the range of wireless routers and access points. By adding a high-gain antenna to your wireless router or access point, you can increase the range of your wireless network by up to four times. An ideal location to place the external antenna is a high location, such as on the house's roof or the windows. But remember to put it vertically so as to receive the strongest signal.

If you live in a large home or office, or if you have a lot of walls and other obstacles that can block the wireless signal, it's worth trying to add a high-gain antenna to your router or access point.


To sum up, there are 4 effective tools to boost your WiFi signal through walls: a WiFi 6 router, a mesh WiFi system, a WiFi extender, and high-gain external antennas. No matter which one you choose, you will reach a strong and reliable WiFi connection you need. Of course, a WiFi extender would be your best solution if you want to solve the problem with the least amount of money.
