The best WiFi extender for Xfinity allows you to eliminate any WiFi dead zones in your home or office. These are those areas where the internet connection is slow or non-existent and always frustrates the heck out of you. 

We'll cover the best WiFi extenders you can use with your Xfinity router, along with the factors to consider when choosing the right extender. But first, let's understand what a WiFi extender for Xfinity is and why you need it.

What Is A WiFi Extender for Xfinity? 

A WiFi extender is a device that extends the range of your WiFi signal, allowing you to access the internet in areas you otherwise wouldn’t without it. A WiFi extender for Xfinity is one that is compatible with Xfinity WiFi routers and will extend their WiFi signal. 

A good WiFi extender works by rebroadcasting the WiFi signal it receives from your Xfinity router. Although Xfinity is a powerful brand that’s renowned for its services, such as high-speed internet, home phone services, and digital television, it doesn’t always mean that the WiFi router will service every area of your home or office. 

If you are using your Xfinity router in a house or office that has thick walls or multiple floors, you’ll feel the WiFi signal getting weaker the further you move away from the router. This is where one of these best WiFi extenders for Xfinity comes in. 

Now that we’ve got that covered let’s help you choose the best WiFi extender for you.

Now that you have a good idea of the best options, let's look at some factors you should focus on when deciding.

How to Choose the Best WiFi Extender for Xfinity

How to Choose the Best WiFi Extender for Xfinity

Here are some crucial factors to consider.

1. WiFi Coverage Range

Different range extenders have different coverage ranges. The coverage range of your range extender is the area within which you can enjoy your WiFi network after installing it. For example, our first pick above – the NETGEAR Wi-Fi Range Extender EX6120 – has a coverage range of 1500 sq ft.

This means that as long as you’re within this area, you’ll be able to enjoy good speeds from your WiFi network.

When considering the coverage range, it’s important to note the area covered by your building or even office. This will allow you to know what range to look for. If you are working in a large office and need as much coverage as possible, we recommend our fifth pick above.

This range extender has a coverage range of 2000 sq ft and supports WiFi speeds of up to 1750 Mbps. Let’s look at speed next.

2. WiFi Speed

You want a WiFi extender that can offer you a stable and fast connection in any part of the room. An important factor when considering speed is the WiFi speed from your Xfinity router. You want to ensure that the speed limit on your WiFi extender is higher or the same level as from your router. 

This will allow you to enjoy the same WiFi speed and performance from your WiFi extender as you would from your Xfinity router

3. Compatibility with Xfinity Routers

It goes without saying that you should select a WiFi extender that’s compatible with your Xfinity WiFi router. However, we’ll mention it because we’re only human, and it can be easy to forget when you’re looking at other factors. 

So, you’ll notice that most of the options we’ve chosen above are universal. This means that they are compatible with almost all WiFi routers. Nonetheless, if you choose to go with one of our picks above, you can be sure that this box is automatically checked. 

Nonetheless, ensure that you double-check this feature if you choose to purchase your WiFi extender from another source. 

4. Budget

As is the case when you’re buying anything, your budget will dictate what you get when it comes to WiFi extenders. The good thing about knowing how much you’re willing to spend on your WiFi extender is that you’ll know what features to prioritize. 

For example, our last two picks are on the higher side in terms of price because they have superior features when it comes to coverage range and maximum connections. Therefore, if you don’t need more than 20 connections at a go or a coverage range of over 1500 sq ft, you can go with other affordable options like our 2nd pick. 

All in all, WiFi extenders for Xfinity are affordable, and you’ll be sure that you’re getting value for your money if you go with one of our options above. Therefore, you don’t have to worry. 

5. Maximum Connections

The number of devices you can connect at a go is important to consider, especially if you plan on using your WiFi extender in a commercial space. For example, if you want to expand the range of your Xfinity WiFi in your restaurant, you’ll want an extender that can support as many connections as possible. 

This is to ensure that there won’t be a moment when someone who needs WiFi cannot connect. We recommend getting a WiFi extender that offers more connections than you need in case there’s a need for an allowance.

For example, you may add a new projector to your household without notice. Having room for extra connections can come in handy here. Btw, if you want to get a very affordable and high-quality projector, check out our guide on the best projectors under $300.

6. Compatibility & Portability

Our third pick – the NETGEAR WiFi Range Extender EX2800 – is a great example of a portable and compact extender. The truth is that you won’t just need to use an extender in your home or office.

Sometimes, you’ll go to a hotel or co-working space and be gravely disappointed by the coverage range of the WiFi. Having a portable extender in such a situation can be a relief for you and those around you. All you’ll need to do is plug it in and enjoy good speeds.

Therefore, if your work or hobby needs you to have strong and reliable WiFi wherever you are, we recommend getting the NETGEAR WiFi Range Extender EX2800, or an equal alternative.
