Wi-Fi Range Extender buyers guide:

There’s a number of things you should consider before purchasing a Wi-Fi range extender. Below we explain what you should look for when buying a Wi-Fi range extender


Wi-Fi range extenders generally aren’t outrageously priced. The most basic Wi-Fi repeaters can be found for less than $100.

Even the newer range extenders that support the most recent wireless protocols and provide performance-enhancing technologies, like beam-forming and Mu-MIMO, cost less than $200.

But just like any technology, usually the more expensive a Wi-Fi range extender is, the better it will be. The more expensive models have more user-friendly features and sometimes can have significantly more range.


Wi-Fi extenders extend your Wi-Fiinternet by communicating with your router via radio waves.

This means that you need a spot for your extender near enough to your router so that you can get an effective broadcast signal, but remote enough so that the network’s range can reach the desired location.

For a small area, a simple WiFi extender should be sufficient. But if you want a powerful WiFi signal to cover a wide area, you’ll need a dual-band WiFi extender that works at 2.4 GHz and 5 GHz.

Also always make sure the WiFi extender is up-to-date with the newest WiFi standards and technology.


Although plug-in Wi-Fi extenders are the most common, they aren’t the only choice when it comes to boosting a weak Wi-Fi signal.

There are bigger extenders that sit on a desk or shelf like a conventional router, and they often offer the best performance. Plug-in units are often less expensive and easier to install with a less effective performance while the larger devices can be more complicated to install while providing better performance.

It’s crucial you figure out which type of extender is right for you before you make a purchase.

Make sure the Wi-Fi extender matches your router

The wireless standard your router utilises may not seem important to you, but it does have an effect on how useful your extension is.

When choosing a range extender, choose one that matches your router’s specs. For example, if your wireless router uses the current 802.11ac standard, make sure your extender does as well. The older 802.11n standard is slower and will slow down your internet usage. 

The latest 802.11ac standard is recommended for Wi-Fi routers, so check to see whether your extender supports it.

Wi-Fi Range Extender FAQs:

Are Wi-Fi extenders the same as mesh networks?

While essentially they do the same thing, Wi-Fi extenders and mesh networks are different.

Instead of adding to an existing Wi-Fi network, a mesh system replaces your whole home’s Wi-Fi network.

There’s usually no point in using them in conjunction with your existing router. So if you want a mesh system it’s best to replace your router as well. If you don’t want to do that, Wi-Fi extenders are a great option.

With a mesh network, instead of having a router and Wi-Fi extenders, you’ll have several similar devices scattered around your home, all of which may be utilised in tandem.

What’s the difference between a range extender and a range booster?

When it comes to Wi-Fi Booster VS Wi-Fi Extender, It’s easy to get confused by marketing jargon.

In reality, there is no difference between a Wi-Fi Booster and a Wi-Fi extender they’re the same thing: Wi-Fi coverage-improving gadgets.

Although manufacturers label their products as “boosters” or “extenders,” there is no obvious distinction between the two.

Are Wi-Fi extenders worth it?

Wi-Fi extenders are absolutely worth it.

As long as you make sure you’ve gone through our buyer’s guide, and made preparations for a Wi-Fi extender, they’re a great solution to a genuine problem.

But everything from price, performance and your more specific needs will be taken into consideration. And always bear in mind there are just too many variables in Wi-Fi for a one-size-fits-all approach. Before you buy a Wi-Fi extender your task is to diagnose the problem and choose the appropriate extender that will resolve said problem.

Do Wi-Fi extenders slow internet speed?

WiFi extenders have no effect on your internet speed.

WiFi extenders work by amplifying the WiFi signal coming from your router and sending it all around your home or office.

As the signal is lengthened the signal’s emission is boosted and this allows the internet to spread farther over any given area as a whole.

What is MU-MIMO?

MU-MIMO stands for “multi-user, multiple input, multiple outputs.” It’s designed to serve densely populated areas, such as stadiums, public transit hubs, airports, and train stations, where many people are simultaneously attempting to access a wireless network. But it’s handy to have around the house as well.

MU-MIMO is a technology that helps coordinate numerous devices, such as WiFi routers and extenders, when communicating with one another faster.

The easiest way to think of it is like this, imagine you’re waiting in line in the school cafeteria and there’s only one person serving food. Using a Wi-Fi router or extender without MU-MIMO, you’ll be served after the people in front of you. However, a router or extender with MU-MIMO, will now have several people serving food, so multiple people in the line can get served at the same time. Now all you have to do is replace, getting food with connecting to Wi-Fi and that’s how, in very basic terms, MU-MIMO works. More people on the Wi-Fi at once without delays.
