Buying guide

The Best Extender Wi Fi 2021 5

How to choose a perfect Wi-Fi amplifier for your home or office?

If you have problems covering your internet router, the best solution is to use a Wi-Fi amplifier. Not all routers have the same specifications, and some can emit a signal over a smaller area than others. That's why, in order not to change the Wi-Fi router , an amplifier is the perfect solution.
But just like routers, amplifiers are different. So how do you choose the right one for your needs? To make your decision-making process easier, we welcome you with a practical buying guide. This way, you no longer have to search for "wifi booster price" or "top repeater wifi" because here you will find all the information you need.

We will reveal how a wifi repeater works, how many types of amplifiers there are, but also which is the most suitable place to place it. Moreover, we will show you the most common mistakes that people make when installing a range extender and what are its most important features.

Why do you have a slow internet speed?

The Best Extender Wi Fi 2021 6

There are many reasons why internet speed does not live up to your expectations. There may be a problem with the router, Wi-Fi signal, or cable. If you have several devices connected to the same network, the speed decreases considerably, this being one of the most common causes of a slow speed. Your phone, home computers, laptops , TVs, and other Wi-Fi devices can make it difficult.

A weak connection can also be the result of placing the router away from devices, or thick walls that block the transmission of the signal. Also, if you open several pages at the same time, the internet will go worse.

How to improve your internet speed

One solution would be to go closer to the router, or change it to a better one. You can also use an application to analyze interference and determine what is in the way of a higher speed.
You can also try disconnecting devices you don't use from the internet. If you don't like these solutions, a Wi-Fi amplifier can improve your connection performance regardless of obstacles, devices, or the number of open web pages.

How does a Wi-Fi amplifier work?

In essence, a wireless range extender starts working once it has established a connection with the router or access point. Once the connection is established, it will forward the signal to your wireless device, such as your laptop or mobile phone.

Most more affordable routers and amplifiers operate at 2.4 GHz and have a transfer rate of 300 Mbps. Their advantage is that they have a better wireless signal and allow you to connect more devices.

On the other hand, newer routers and amplifiers are dual-band. This means that in addition to the 2.5GHz frequency, they also have a 5GHz frequency. This has the advantage of a transfer rate of up to 1300 Mbps, which translates into better internet speed. The disadvantage of this frequency is that it has a smaller coverage area.

Types of Wi-Fi amplifiers

Depending on the model, a wifi amplifier can be powered from the socket, to a USB port or with batteries. The most common on the market is the plug-in amplifier. The ones with batteries are most often used for surveillance and burglary detection systems, and the USB ones are preferred by those who want increased mobility.

Plug-in amplifier

Usually, the amplifiers that connect to the outlet are small, compact and very elegant. They fit in any room because they do not attract attention and do not change the design of the room. It is easy to install, both at home and at work, and their configuration is extremely simple.

One of the main advantages is that it does not require wiring, but only needs to be plugged in. It is practical, however, as you may realize, you are required to have a socket on hand to power it.

Amplifier with internal battery

These types of Wi-Fi amplifiers look like a router with external antennas.

From a practical point of view, such an amplifier must find its place on a flat surface, which means that a certain place on the table will be entirely his. They are larger and heavier than those with a power supply. Internal battery amplifiers are not very popular and tend to be more expensive.

Where to position your amplifier for optimal coverage?

We start from the main purpose of a wifi amplifier: to extend the signal so as to cover the "dead zones" where the signal does not reach. Once you have chosen the right product for your needs, the next step is to look for the best place to place it.

The best location is halfway between the router and the "dead zones", where the wi-fi signal is very weak or does not reach at all. Whether it is a wifi booster upc or any other kind of amplifier, this general rule applies in all cases.

To determine these areas you can use either an application that shows you the signal strength of your router or your mobile phone. If you use your mobile phone as a search tool for these areas, keep in mind the signal strength when you are close to the router. Then, move away from it slightly and see where it starts to drop significantly. If the signal drops to zero, you are in a dead zone. This is where you should place the amplifier.

Of course, you can also use an application to detect these areas. The good news is that many of them are free and very efficient, there are various for both smartphone and laptop.

Beware of possible obstacles that could affect the signal

Remember that solid objects such as thick walls and furniture can block the signal. But once you find out about those dead areas, you can start taking action.

You can move the router to a more central area, or adjust its antennas so that they stand upright. Of course, you can also use an amplifier, as we have established so far.

Test the strength of the Wi-Fi signal

As mentioned above, the power of the Wi-Fi signal is easily tested with a smartphone. Keep track of the steps you take until you reach the dead zone, paying attention to the rising and falling Wi-Fi lines.

However, these lines do not tell you much. If you want to have a better understanding of the power of the Wi-Fi signal, you need to use an application to do an informative analysis. We recommend AirPort Utility (for iPhone and iPad) or Wi-Fi Analyzer (for Android).

The signal strength is measured in dBm (milliwatt decibels) and is expressed only as negative values. The maximum power of the signal is -30 dBm, and when this value increases, the power decreases. The lowest value is -90 dBm, at which point it will be difficult even to connect to the network.

The most common mistake people make when installing a Wi-Fi amplifier

Such a device is not at all difficult to install. However, some people continue to make the same seemingly harmless mistake: place the amplifier in the wrong place. As mentioned above, finding the perfect place to position it must be chosen strategically, halfway between the router and the "dead zones", so that the coverage area increases.

The amplifier can double the coverage of the Wi-Fi signal, but this is only done if its location is done properly. Some people use the plug-in amplifier depending on the outlets available in the apartment, but this will not always improve the signal.

So follow the tips above, determine the "dead zones" and place your device halfway so you can enjoy the best performance of your wireless signal amplifier.

Will the Wi-Fi amplifier have any impact on the speed of your internet connection?

An amplifier communicates with the router via Wi-Fi, which means that there will be a slight decrease in speed when the devices use the same signal. Every time data passes from the router to the amplifier to your smartphone or other device, it slows down.

The reason? The amplifier must divide its data between the interaction with the router and the interaction with the connected devices.

This phenomenon is normal if the amplifier uses only Wi-Fi. However, if you use an Ethernet cable to connect the amplifier to the router, the signal speed will be better. What other options can you try to improve your internet speed? Move the amplifier a little closer to the router, one-third of the way between it and the "dead zones".

Make sure the amplifier supports your router's standard. Most amplifiers work with any router, the most common standard being 802.11n. If you have an older b / g router, it may not work as well. Also, before setting up an amplifier with a router, make sure that both the router and the amplifier have the latest updates. firmware.

What to look for when choosing a Wi-Fi amplifier

Before buying an amplifier, it would be ideal to pay attention to a few aspects. We will discuss each one further.

Wireless security

Wi-Fi amplifiers can be attacked by viruses, hackers, or programs specifically designed to gain unauthorized access to a computer system. "Wi-Fi Protected Access", in free translation, "Wi-Fi Protected Access" is a security protocol, and it is divided into 3 types:

  • WEP is the most widely used security protocol since 1999. For an encrypted data transfer to work, both systems at the beginning and end of a data transfer must use the same encryption / decryption key. WEP only performs this action if both systems are authorized.
  • WPA emerged in 2003 as a solution to the vulnerabilities that WEP presented. This security protocol uses the TKIP (Temporal Key Integrity Protocol) which periodically changes the key used by the systems. This prevents intruders from creating their own encryption key to match the one used by the secure network.
  • WPA2 has replaced TKIP encryption with CCMP, being the most secure so far. For home users, this option is the safest.
    The data sheet of the amplifier shall indicate the safety protocol which it accepts.

Dual-band system

Dual-band refers to the bands that your router uses to output signal. If efficient communication with the router is desired, the amplifier must accept its bands. A dual-band amplifier allows the simultaneous operation of the two bands for devices connected to the network, obtaining a better data transfer speed over a larger area.

A single band amplifier will connect to the router only through the 2.4 GHz band, being compatible with the 802.11b and 802.11g standards. However, there are amplifiers that also have a 5GHz band, which allows them to connect to both 802.11n routers and previous standards (b and g).

  • 2.4 GHz:
    This type of frequency will support a data transfer rate of up to 600 Mbps. This type is suitable for transmitting the signal through solid objects.
  • 5 GHz:
    The 5GHz band offers higher speeds, but has a shorter range, and the waves do not penetrate walls and solid objects. This lane is less crowded, which is why the speed will be more satisfactory.

Three-band system

In addition to the two bands mentioned above, there are also amplifiers that can use 3 Wi-Fi frequency bands. In this way, you will be automatically connected to the fastest and least crowded network.

This makes a multi-band Wi-Fi amplifier suitable for families who want to connect more than 10 devices to the network at the same time. A three-band router has 2 5 GHz networks, which means you will always have a stable connection. A three-band router recognizes the capacity of a device and connects it to the band that fits best.

What else do you need to consider?


When we talk about compatibility we refer to the standards of each router. The Institute of Electrical and Electronics Engineers (IEEE) has decided what the standards for encryption are. All of these standards are 802.11 with a letter after. The rule is: the bigger the letter, the faster the network speed.

So when buying a Wi-Fi amplifier, check what type of standard it suits. Simply put, if you have an 802.11n router at home, make sure the amplifier supports this standard.
Even if you buy an amplifier that offers the highest performance, if the devices in the house do not support its standard, it will be useless. You will not benefit from the true speed that the amplifier offers because the devices will stop at the speed they support.

In this case, you do not need to purchase an amplifier that supports the latest standard if your home devices do not use the same standard.

But how are the standards different from each other?

  • "N" was ratified in 2009 (802.11n) and allows data transfer of up to 600 Mbps;
  • "B" was the first standard to provide data transfer of up to 11 Mbps in the 2.4 GHz spectrum;
  • "A" was the next evolution, providing data transfer of up to 54 Mbps in the 5GHz spectrum;
  • "G" appeared shortly after 54 Mbps in the 2.4GHz spectrum was activated;
  • "Needle" is the next evolution of Wi-Fi and wireless speed, activated by more than one gigabit per second.

Additional functions

The next important issue is whether or not the amplifier has extra functions. As you may already know, each Wi-Fi amplifier is unique in terms of features. However, there are convenient features that would help you, such as the WPS button. Usually, the WPS button makes it easier to connect the router and the amplifier by simply pressing it.

There are other features, depending on the type of Wi-Fi amplifier you are looking for.
We are talking about reset buttons, Ethernet cable port that can improve speed, speed indicator LEDs and USB ports to connect the amplifier to laptop, TV .
If you need such features, you will need to find an amplifier that meets your expectations.


Next we will discuss the design of the amplifier. This aspect is of particular interest to those who are actively concerned with the way the house looks to them. If you do not want to spoil the color harmony in the room, or simply want a discreet device, the good news is that there are a lot of models on the market.

As you can already see, the manufacturers have made both small amplifiers and larger amplifiers. The bulky ones are suitable for people who are not bothered if this device catches the eye.

Discrete, small and compact amplifiers can be easily integrated into the environment of any room. Adherents of minimalism could also opt for a subtle amplifier, and the market offers various options in this regard.

How easy will the installation be?

Another topic of interest is how to install the amplifier. Plug-in amplifiers are easy to install. Most of the time all you have to do is plug it in, press the WPS button on both the router and the amplifier. In a maximum of 2 minutes, the connection of the two devices is created, without the need for any password.

However, you may need an application to set up your device. There is a good chance that the amplifier you buy will come with its own software or an application that will help you reach its best performance. Do not hesitate to use it because in this way you will be able to benefit from a stronger signal and a higher internet speed.

Each amplifier is configured differently, but in the instruction manual you will find all the information you need to perform this step in the shortest time.

Radius of coverage

Last, but not least, is the range of your chosen amplifier. There are amplifiers that emit a very large signal area for people who need Wi-Fi signal over a wide area.

But amplifiers that cover a large radius are more expensive. That's why if you simply want to improve the signal quality in your home by eliminating "dead zones", an amplifier with a coverage area of 50 meters is suitable for you.

How to protect your network

Protecting your internet network is one of the most important things to keep in mind. Cyber security is not an issue that you can avoid because data protection is essential. For ordinary people who do not know advanced security techniques can be an overwhelming topic. You need to know that it's easy to keep your data safe if you follow a few steps:

  • Choose a unique and hard-to-guess router login name and password
    Avoid easy-to-guess passwords and phrases such as "123456", birth dates, or your own name. Choose a password that contains letters, symbols, and numbers. For extra security, enter some capital letters.
    It is recommended to change the password once every half year.
  • Enable WPA2-PSK encryption
    Wi-Fi security has evolved significantly. The router that still uses WEP must be replaced with WPA2-PSK. WPA2-PSK can be configured with a password of up to 63 characters. Having such a password should be sufficiently protected.
  • Enable the firewall both on the router and on all connected computers
    There are two types of firewalls : hardware and software. Your router works as a hardware firewall, while Windows includes a software firewall. There are other third-party firewalls that you can install. If you have connected a computer to the Internet without a firewall, it can be affected by viruses and hackers.
    Home routers use network address translation (NAT) to share a single IP address from the Internet service to all computers in the home. NAT acts as a firewall that prevents unknown requests received from reaching the computer. Depending on the router, you may also be able to block certain types of outbound traffic by entering the router settings.
  • Specify which devices can access your Wi-Fi connection
    You can choose to allow all new devices to connect to your internet network. This option is not recommended because it is not safe. Instead, it is recommended to deprive your Wi-Fi network and allow only those who have the password.
    The access rule will not affect devices that are already connected, but only those that are to be connected, in the sense that they will be asked for the password.

Questions and answers

Do I have to manually connect the router and amplifier?

You can connect either manually by pressing the WPS button or using an application.

Are the Wi-Fi amplifier and the mesh system the same?

No, an amplifier extends the Wi-Fi signal from the main router. The mesh system consists of several devices (nodes) located around the house, which communicate with each other to cover the entire area.

How far can the signal from an amplifier go?

Depending on its quality, it can double the area covered by the signal from the router, but most cover only a few tens of meters.

Can I use two amplifiers at the same time?

Yes. But you should know that the speed of the boarding school will decrease a little.

Can the Wi-Fi signal go through walls?

Yes, the signal from the router, but also from the amplifier can pass through walls, solid objects and furniture, but it will not have the same intensity as when you are in the same room with the router.

What materials can block the Wi-Fi signal?

Thick brick walls, solid wood furniture, metal, water, television and any physical obstacle can block the Wi-Fi signal.


If you have areas where the signal from the router does not reach, or you want to double its coverage, all you have to do is buy a Wi-Fi amplifier.

A wifi amplifier for your phone, laptop, TV or any other device is useful, especially if there are several of you in the house. This is an extension of the router, taking the signal from the main source and taking it to the "dead zones" that the router does not touch. If you search the internet for upc reviews you will find that these devices work well and people are satisfied with their performance.

In this article we have presented you the best amplifiers on the market so that you know what choice to make. Moreover, we have given you some useful tips on a better internet connection, how to ensure your network security and what to look out for when buying such a device.
