How To Choose The Best WiFi Extender For Concrete Walls?

You might be considering buying a Wi-Fi extender for concrete walls because they weaken your Wi-Fi router signals. While trying to search for the best WiFi extender for concrete walls, you will undoubtedly see various brands that claim to be the best, while in reality, not all of them are.

Here are a few factors you should look for when trying to buy the best WiFi extender for concrete walls:

Network Setup

The network setup for the WiFi extender should be easy to follow. Many models feature user-friendly software and even animated guidance for added convenience. The WiFi extender should be able to detect the optimum location inside the house and assist with maximum node coverage.


The WiFi extender you opt for should have a design that has a mesh framework that features options to increase overall performance.


The presence of a multi-band means you get a dedicated network meant for improving the efficiency of mesh systems.


Stable WiFi systems have beamforming, especially when we talk about systems that use the 802.11ac/ax protocols to operate. Beamforming helps increase the device performance by boosting the usage of the wireless spectrum via a focus on radio signals. The process gives you more signals.

Multi-User Multiple Input Multiple Output Technology

A Wi-Fi extender with MU-MIMO technology has the upper hand. MU-MIMO stands for Multi-User Multiple-Input Multiple-Output and is also known as AC Wave 2 or Next-Gen AC. This unique technology allows multiple devices to connect to the Wi-Fi simultaneously without slowing down the network speed. Hence a Wi-Fi extender with integrated MU-MIMO technology can be beneficial if you run multiple wireless devices at once.

Ethernet Ports

The best mesh WiFi systems tend to have at least one Ethernet port that is meant for hardwired links. You will find the Gigaports attached to the cable or modem for optimum output and speed.

Data Transfer Rate

The data transfer rate is the maximum internet speed a Wi-Fi extender can provide. This speed is generally mentioned in numerical along with Mbps (Megabits per second) or Gbps (Gigabit per second). An extender with a higher data transfer rate is usually ideal for larger areas with more devices.

Wi-Fi Coverage

The Wi-Fi coverage refers to the max range or distance you can extend to the Wi-Fi signals. To get the best WiFi extender for concrete walls, you should check how many sq. ft the Wi-Fi extender covers. A higher coverage range is better for larger locations to maximize Wi-Fi connectivity.

Difference Between a Wi-Fi Extender And Wi-Fi Mesh System

While searching for the best WiFi extender for concrete walls, you’re bound to stumble upon terms such as Wi-Fi extender and Wi-Fi mesh system/router. While the terms seem similar and might be used interchangeably, there is a marked difference between the two.

To help you understand better, here is the distinction between a Wi-Fi extender and a mesh network.

Wi-Fi Extender

A Wi-Fi range extender is a separate device that helps to extend your Wi-Fi. This device works by connecting to an existing Wi-Fi router network, intercepting it, magnifying the signals, and rebroadcasting it with a new network name. Hence when signals become weak from a Wi-Fi router, a Wi-Fi extender increases the coverage range. You can manually switch from the router to the extender’s network this way.

Wi-Fi Mesh System

A Wi-Fi mesh system is a hybrid system to spread wireless connections through a larger area. This system collects devices that include the main router and a series of satellite modules, AKA nodes. One node is connected to the main router, while the rest are placed in different locations to cover Wi-Fi dead zones.

Unlike a Wi-Fi extender, all devices under the mesh system are part of the same wireless network and have the same SSID and password.

What’s The Problem With Concrete & Brick Walls?

Different building materials tend to interact differently with Wi-Fi signals. The US National Institute of Standards and Technology experimented with concrete as one of the thickest materials and the worst for Wi-Fi to pass through as it partially absorbs the signals.

Additionally, when rebar is used to strengthen concrete slabs, the metal further weakens the Wi-Fi signals. Hence, concrete walls can highly affect radio signals attenuation.

Where To Place Your Router If You have Concrete Or Brick Walls?

It is recommended to place a router in a central location. The device should be away from walls. For multi-story homes, the device should be close to the most central floor to enjoy the best signals.

2.4 GHz vs. 5 GHz. Band For Penetrating Concrete & Brick Walls

Wi-Fi signals are transmitted as frequency bands. These are ranges of radio waves within the wireless spectrum divided further into Wi-Fi channels.

There are two kinds of frequency bands, 2.4 GHz and 5 GHz. The 2.4 GHz is lower in frequency, has a more extended range, and can penetrate through obstacles such as furniture, walls, etc. The 5 GHz band, on the other hand, has a shorter range but offers a higher internet speed.

To get the best WiFi extender for concrete walls, look for the bands the device works with. A single-band Wi-Fi extender can suit concrete walls, but an extender that supports dual or tri-band can offer better coverage and internet speed.

FAQs – Best WiFi Extender For Concrete Walls

Do Wi-Fi Extenders Work Through Concrete Walls?

Concrete is one of the worst building materials for Wi-Fi signals to pass through. Due to this, additional devices are needed to supply Wi-Fi signals all over an area with concrete walls.

Wi-Fi extenders do work through concrete walls. However, you need to find the best WiFi extender for concrete walls with high Wi-Fi speed and coverage range. Additionally, it should work with multi-frequency bands to ensure a stable internet connection.

How Do You Get Wi-Fi Through Concrete?

To get Wi-Fi through concrete, you need to extend the range and strength of your existing router’s signals. To do that, you can either invest in a Wi-Fi extender or get a whole-home Wi-Fi mesh system. The Wi-Fi extender and mesh system capture weak signals, boost them, and then rebroadcasts to an entire area with concrete walls.

How Do I Get Wi-Fi To Penetrate a Wall?

Wi-Fi signals can usually penetrate through walls. However, the building material and thickness can affect this ability.

To get Wi-Fi to penetrate a wall, you need to extend your Wi-Fi signals to reach dead zones. You can extend the range by getting a better Wi-Fi router or a Wi-Fi extender for an existing router. You can also purchase a Wi-Fi mesh system, set up a powerline LAN, or even place additional access points for Wi-Fi to penetrate through walls.


Getting yourself the best WiFi extender for concrete walls is the easiest solution to experience a stable internet connection, even with brick walls around. We hope the information and reviews presented in our WiFi extender for concrete walls review lists helped you out.
