If you want to extend the internet coverage in your home without compromising the speed, then a WiFi extender is all you need. The best WiFi extender of 2021 gives the strongest signal to multiple devices in all rooms of your home, without any decrease in internet speed. You might be wondering how this device works and what models you can choose.

This article will try to provide you with all the information that you’re seeking. To cut the chase, I have selected ten of the best WiFi extenders and review their performance.  Keep reading to find out the basic background of WiFi extenders and how to choose the best one out there.

What Is  A WiFi Extender?

Similar to a WiFi repeater, a WiFi extender is used to increase the coverage area of your wireless network. This device helps you double the coverage range of your WiFi network, connecting further to every corner, floor, and even outdoors. It receives your current WiFi signal, amplifies it, then transmits the boosted signal.

A WiFi extender links with your router using either a wireless or wired connection. Most of the time, you can plug it in your AC outlet near the areas where you like a stronger WiFi signal. If you want stronger WiFi, consider connecting your device via the extender’s Ethernet port.

How Does A WiFi Range Extender Work?

A WiFi extender has two wireless routers, the same wireless router that you use in your house. Between the two routers, one picks up your current WiFi network and sends it to the other router. The second router then broadcasts the improved signal, working as a middle-man to transfer the connection.

The crucial part is finding the best location for your extender. It should be near to your router to grab the signal and further away so that it can transmit that signal to the room or space where you want a stronger WiFi signal.

How Should I Set It Up?

WiFi extenders are simple to set up. First, put the extender in a place where it can receive your current WiFi network and then plug it into the AC outlet. Log into the WiFi extender via the web and input the important details, like user ID and password of your current network.

Again, the placement plays a key role in the optimum performance of your WiFi extender. Create a floorplan of your home and determine the key locations of your router, AC outlets, and dead spots. The best placement of your WiFi extender should be between the router and the room where you need the best signal boost.

I particularly love the slim design because it stays put on the socket and leaves another outlet free for another device. The antennas are significantly long to pick up strong signals, and the setup is super easy.

My only gripe is that the advertised 2,500 square feet range is slightly exaggerated. Also, the instructions about the User ID are concealed in the instructions for the WiFi setup. Regardless, SETEK is still a promising WiFi extender for the price.


  • Super long antennas pick up more signal
  • Available at a reasonable price
  • Good security protection
  • Protects the device from overvoltage
  • Stays put on the outlet


  • The actual range is less than advertised
  • Instructions are difficult to follow

How To Choose A WiFi Range Extender Of 2021?

Just like routers, WiFi extenders aren’t built the same. Before you get a new WiFi range extender, here are some things that you need to consider.

  • Standards Compatibility

Standards compatibility is crucial to ensure that you get a better unification between your router and the WiFi extender. This specification is somewhat associated with the frequency and period of your router. If you don’t know the supported standards of your router, look at its specifications.

The safest way is to select universal compatibility that’s compatible with IEEE 802.11 a/b/n/ac routers. Other standards compatibility are IEEE 802.11 a/b/g/n, 802.11 b/g/n, and 802.11 a/b/g/n/ac. The latest generation of WiFi signalling uses 802.11ac that supports both 2.4 GHz and 5.2 GHz bands.

  • Single Band, Dual Band, Or Triple Band WiFi Bands

A single-band WiFi extender works on 2.4 GHz. It has a longer range because it can perforate through walls and doors. However, this technology usually experiences interference and works relatively slower than dual and tri-band extenders.

A dual-band WiFi booster works on both 2.4 GHz and 5.2 GHz. This technology has double the bandwidth of a single-band WiFi extender. It’s less prone to interference, but the 5GHz band has a shorter range.

A tri-band WiFi range extender usually works on one 2.4 GHz and two 5GHz bands. Obviously, it can transmit thrice as much bandwidth than their single-band counterparts. They have the least interference, but they’re the most expensive.

  • Security

To maintain the safety of your network, it’s your WiFi extender must support an effective security protocol. Current WiFi extenders support WPA2-PSK security arrangement. The most secure protocol is WPAWPA2-PSK.

  • Budget

Your budget depends on how much you can afford. Getting the most expensive WiFi range extender isn’t always the best decision if the specifications don’t meet with your current router.

The best decision is to choose a WiFi extender that meets your needs at the most reasonable price. The price of the WiFi extenders can go as low as $20 and high as $100.

  • Easy To Use

The best WiFi range extenders should be easy to use even for beginners. There should be a web-based option to configure the settings, as well as a mobile app for convenience. Most models have LED lights to indicate the signal strength so that you’ll know where to place the unit.

As for the setup, it’s as easy as pushing the WPS button. Instructions are also key for a successful configuration.

  • Plug-In Or Desktop?

Plug-in extenders are more compact than desktop versions, but they have limited ports. They only have to be loaded into an AC outlet to work. Since they often cover the entire outlet, most models use internal antennas or flexible antennas to be unobtrusive.

If you want to connect more devices to your extender, a desktop extender might be suitable. This type of range extender contains multiple LAN ports and external antennas. However, they’re more expensive and bulky.

  • Consider An Upgrade

If you’re thinking of improving your network, it’s nice to consider a new mesh-based WiFi system. This system aims to cover your entire home with a wireless connection. It includes several components such as the main router and various satellite modules that you scatter throughout your house.

All these components are part of one wireless network and share a similar password and SSID. This means that you can travel from one room to another without having to input your login details. While extenders use radio bands, WiFi system satellites utilize a more sophisticated mesh technology.

FAQ (Frequently Asked Questions)

Where should a WiFi extender be placed?

  • The perfect location of your extender is midway between your router and laptop. Make sure that the extender is placed within the router’s wireless range. If you need to utilize a different area, place the extender near the device, but still inside the router’s wireless range.

Do WiFi extenders really work?

  • Sure, they do! WiFi extenders grab a current WiFi signal, amplify it, and transfer it to further areas of your home. The best outdoor WiFi extender of 2021 can even cover your yard, without reducing the speed.

Do I need a WiFi extender?

  • If you need to experience the same strong connection anywhere at home, then you need a WiFi extender. A WiFi extender can help extend the same reliable connection in the far corners of your house.

What is the strongest WiFi extender?

  • The TP-Link AC2600 RE650 is the strongest WiFi extender because it can boost your internet speed up to 2600 Mbps within the 14,000 square feet range. This unit uses four external antennas to grab your router’s signal right away.

What is the difference between a WiFi booster and a WiFi extender?

There’s not much difference between these two terms. A WiFi booster is similar to a WiFi extender in the sense that they help enhance internet signals.

How do you know if you need a new router or extender?

  • If you have intermittent internet connections and you can’t log on anymore, then you need a new router. If you want more range, an extender might be all you need.


A WiFi extender is essential if you want an internet boost throughout your home or office. The best WiFi extender of 2021 is the TP-Link AC2600 RE650 because it provides the widest coverage range and fastest internet speed up to 2600 Mbps.
