How to Boost WiFi Signal?

Do you struggle with slow internet and internet dead spots inside your home or place of work? Poor WiFi can be caused by WiFi blocking materials, such as thick walls, metal, concrete, glass, and signal interference from other devices.

Under such circumstances, the first thing you should try is relocating your router. Simply moving the router to an open central location can fix your wireless coverage problem. Unfortunately, sometimes it’s not that simple. Sometimes extra measures need to be taken, such as replacing the router's antennas, purchasing long-range antennas, or even purchasing new WiFi equipment, which might or might not improve the coverage area.

If you have tried everything you can to improve your WiFi signal to no avail, consider trying out a WiFi signal booster. They are specifically designed to improve your WiFi network’s coverage.

What is a WiFi Booster?

WiFi Boosters (also known as internet boosters) expand your WiFi system's coverage area by boosting or amplifying the wireless signal and broadcasting it into the desired areas. As a result, you will no longer have to deal with poor WiFi in your home or business.

Different types of WiFi booster models are available; they vary in design, range, amplification power, and frequency band usage.

  • Wall Plug or Desktop Design: There are two different types of booster styles available. Some simply plug-in to a power source and are great for improving the signal in one room, while others sit on a desk, table, or shelf and use stronger external antennas that are capable of improving the signal in multiple rooms.

  • Range: Most routers have a range of 150-300 feet. Any device outside that range will experience connectivity issues. Depending on the WiFi booster model, on average they can increase the range by 300-2,000+ sq ft.

  • Frequency Bands: There are two types of WiFi signal boosters – single-band and dual-band. Single-band boosters only utilize one frequency band (2.4GHz or 5GHz) to transmit data. On the other hand, dual-band WiFi boosters use both GHz frequencies to transmit data; one band solely communicates with the router, and the other band talks to the wireless devices.

How Does a WiFi Booster Work?

WiFi boosters wirelessly connect to an access point, such as a wireless router or hotspot. The WiFi booster grabs the signal being transmitted by the access point and amplifies it for better use. Usually, boosters are coupled with stronger antennas that help broadcast the signal further and cover larger areas.

The location of the WiFi booster is extremely important. You want to place it close enough to the access point to receive a signal, but far enough away to cover the problem areas. Ideally, you should look for the area that doesn't have a strong WiFi connection and plug the booster into a wall outlet halfway between the target area and the router.

Most WiFi boosters have pretty simple setup processes. Many utilize the WPS (WiFi Protected Setup) button, which makes the installation process super-fast. Simply press the button on both devices and the WiFi booster will connect to the router. Of course, different WiFi signal booster manufactures (Netgear, Tp-Link, Linksys, D-Link, Asus, Orbi, and Eero) might require additional steps.

After completing the setup process, the booster can start working its magic; it will grab the existing WiFi signal and extend its coverage area.

The last step would be to connect your phone, laptop, tablet, and smart home devices, to the WiFi booster. To do so, you would go into the WiFi settings on your wireless device, click on the WiFi booster's network name (SSID) and enter the password. The password might be the same as your current network, or you might've created a different one during the set-up process. Once connected to the booster, you will be able to enjoy a reliable internet connection in places that originally received poor signal strength.

Do WiFi Boosters Only Work with Wireless Devices?


WiFi boosters work with wireless and wired devices. The majority of boosters have at least one ethernet port that can be used for printers, computers, smart TVs, and gaming consoles.

The setup process would be slightly different than the one discussed earlier. Rather than wirelessly connecting the devices to the booster, you would use ethernet or gigabit ethernet cables to wire the device to the booster.

Do WiFi Boosters Really Work?


As long as you have a wireless signal in your home or business, WiFi boosters are guaranteed to improve the signal's range.

For optimal results, don’t hide the booster behind furniture, in a gap between your living room couch and the wall, or place it near appliances that can interfere with the signal. Doing so will degrade the WiFi booster's range and power, which might cause unsatisfactory results.

How would I Know if the WiFi Booster is Working?

The first sign showing that the booster is working is experiencing better signal in the weak zone and dead zone areas.

But, if you are a person of numbers and prefer actual proof, speed tests are great tools that can be used to analyze WiFi signal improvements. To visually see the difference, you will need to conduct multiple speed tests; one with just your WiFi connection and the other with the WiFi booster. Ideally, you would want to record the results to have a side by side comparison.

Do WiFi Boosters Increase Internet Speed?

The internet speed you receive from your internet service provider (ISP) is the bottleneck, a WiFi booster will not increase your internet speed.

However, WiFi boosters use powerful amplifiers and antennas to boost and broadcast the signal in a very efficient manner. As a result, it appears as if they improve your internet speed.

For example, let say you purchased a WiFi booster on Amazon that supports up to 750 Mbps, but your internet plan only provides you with a max of 300 Mbps under perfect conditions. The WiFi booster will not magically increase the internet speed from 300 Mbps to 750 Mbps, it only works with what's available. The booster will take the existing signal and facilitate a stronger signal, which will allow the connected devices to experience faster WiFi speeds.

Are WiFi Boosters Secure?

WiFi boosters use the same level of security as WiFi routers - WEP, WPA, and WPA2, with WPA/WPA2 being more secure. In 2019 a new security protocol was introduced, known as WPA3. The new protocol improved the security features within public and private WiFi networks, making it more difficult for hackers to access your wireless network.

Do I Need a WiFi Booster?

Not sure if you need a WiFi booster? Here are 3 reasons why you might:

  • Are there areas in your home that don’t get a WiFi signal or have slow WiFi?

  • Do you have the latest WiFi technology (WiFi 5 or WiFi 6) and you’re still suffering from slow speeds, buffering, and dead spots?

  • Does your WiFi connection worsen as you walk around your home?

If you responded yes to one or all of these questions, then you do need a WiFi booster. Sometimes the latest WiFi technology is not enough to cover every nook and cranny of your home or office, especially in large homes that exceed the WiFi routers range. WiFi boosters are much cheaper than purchasing a new router and provide an easy way of improving your WiFi coverage.

Are There Alternative WiFi Range Extending Options?

While WiFi boosters a great, it's also good to know about the different WiFi range-extending options available and how they differ from boosters. The top three alternatives are WiFi extenders, powerline adapters, and mesh networks.

What’s the Difference Between a WiFi Booster and WiFi Extender?

WiFi boosters and WiFi range extenders (also known as WiFi repeaters) are often used interchangeably. While they both improve your WiFi coverage area, they work in slightly different ways.

Wireless range extenders capture your network's existing signal and rebroadcast the same signal into the desired areas. On the other hand, WiFi boosters capture your network's existing signal and boost or amplify that signal. Both give you the same end result, but WiFi boosters have that extra flair.

What's the Difference Between a WiFi Booster and a Powerline Adapter?

Unlike boosters, powerline adapters use the electrical wiring in your home to extend the WiFi signal, hence the name. Powerline kits are composed of 2 adapters; one is plugged into a power outlet near the router, and the other in the area where you need a signal. Connect the first adapter to the router via an ethernet cable and the second to an ethernet device. After the connection has been established, the internet signal will travel through the electrical wiring and provide the wired devices with a reliable connection. In addition, the second adapter also broadcasts a wireless signal to extend the WiFi range.

What's the Difference Between a WiFi Booster and a Mesh Network?

Both WiFi boosters and mesh networks extend your home WiFi network's range, but are very different in various aspects:

  • Functionality: Mesh networks are composed of 2-3 mesh extenders, also known as nodes, while boosters usually consist of one device. The nodes are designed to blanket your entire home with a reliable, high-speed, WiFi connection. One of the nodes would be wired to the modem, as opposed to wirelessly connecting to the router. Essentially, the connected node will be taking on the job of the router. The remaining nodes would be located around your home. Similar to the booster, one node will need to be located halfway between the target area and the "router". Additional nodes don't need to be within a certain distance from the router, they do, however, need to be a certain distance from another node. The wired node will wirelessly share its internet connection with the other nodes. As a result, rather than using one unit to broadcast the internet signal, you have multiple units broadcasting internet signals to provide you with the best WiFi coverage.

  • Seamless Network: Mesh nodes work together to create a seamless home network, meaning the whole system operates under the same SSID and password. As you walk around your home, your device will automatically connect to the closest node. In contrast, WiFi boosters tend to create a new network with a different SSID and password. As you move around your home, you might have to manually switch between networks to connect to the closest one.

  • Price: Mesh networks are made up of extremely smart technology and tend to cover larger areas. For that reason, they are a lot more expensive than WiFi boosters. Some of the best WiFi boosters range from $50-$80, while mesh network kits range from $200-$500+.

  • Number of Wireless Bands: WiFi boosters utilize one or two bands to transfer data. Mesh networks take it one step further; many mesh devices are tri-band. They transmit one 2.4GHz signal and two 5GHz signals. One band is used to communicate with the router while the other two are used to communicate with more devices at the same time. In other words, tri-band devices have double the bandwidth on the 5GHz band. As a result, throughput increases, speeds improve, and congestion decreases.
