6 Best WiFi Extenders for Xfinity

WiFi is an essential aspect of our daily lives. We are all used to having solid internet service, and it can be a real pain when you experience an interruption or delay.

Even if your home or office is equipped with WiFi from a good provider, you still might not have good coverage in all areas. That’s where an extender comes into play.

Here, we will take a look at the best WiFi extender for Xfinity to help you get the service you need.

Who Should Get This

If you want to be able to access your WiFi in nearly all areas of your home or office, there’s a good chance you’ll need an extender.

Your standard Xfinity internet router is simply not going to be able to put off enough of a signal to reach every nook and cranny of your home.

If you live in a small space or have not experienced any dead zones, then you might not need a WiFi extender.

Your router will provide a certain amount of coverage, and you won’t need to extend if you don’t have any issues.

Even so, users who want fast service and definite coverage in all areas should have a good extender around just in case. They are fairly cheap and easy to use.

Best Wifi Extender for Xfinity: Our Picks

Few extenders will give you better results than the ones covered in the following sections.

1. Netgear WiFi Range Extender EX3700

  • Best for: Overall
  • Key Features: Small and easy to use. Extremely compact. Sets up quickly. Lower price point. Widely compatible.
  • Coverage: 1000 square feet
  • Dimensions: 2.64 x 1.54 x 2.17 inches
  • Transfer Rate: 750 Megabits per Second

The EX3700 Extender from Netgear is one of the best devices on today’s market when it comes to getting more from your Xfinity signal. Not only is it extremely small and compact, but it offers excellent coverage as well.

The 750 Megabits per second transfer rate goes a long way too. It supports 15 different devices, meaning that everyone in your house will get plenty of service.

If there is a setback, it’s that this is not the fastest extender on the market. The transfer rate is solid, but you’re not going to see the lightning speed you might find in similar models. If the specs don’t bother you, however, it’s a great choice.

2. TP-Link AC1750

  • Best for: Coverage
  • Key Features: Quick transfer rate. Connects up to 32 different devices. Wide coverage area. Easy to use.
  • Coverage: 2000 square feet
  • Dimensions: 3 x 6.4 x 2.6 inches
  • Transfer Rate: 1750 Megabits per Second

If you’re someone who needs a large signal, the TP-Link AC1750 may be the extender for you. The device can be set up in a matter of minutes by just about anyone, and gives you an amazing 2000 square feet of total coverage.

On top of that, it connects 32 different devices. That amount means it will work for any household, individual, or family regardless of the devices they use.

This is a larger item, which may put some people off, and it’s on the more expensive side of the spectrum. Even so, it’s hard to find a better Xfinity extender with such a wide range.

3. Tenda Nova MW3

  • Best for: Usability
  • Key Features: Incredibly simple setup. Strong coverage. Seamless roaming and high capacity. Secure mesh network.
  • Coverage: 3500 square feet
  • Dimensions: ‎3.54 x 3.54 x 3.66 inches
  • Transfer Rate: 1200 megabits per second

The MW3 is an excellent extender that can boost your Xfinity signal from any part of your house. The small device, which comes in a variety of different pack options, has a strong 35000 square feet of coverage. It creates an incredibly stable Wi-Fi mesh network as well.

You’ll have no network dead zones when using this, nor will you have any trouble getting started. It’s easy to set up, and takes just a few minutes to go from the box to a fast, fully working network.

The signal can be a bit uneven at certain times. Some people may not like that there’s only one LAN port per unit. Even so, the multiple boxes help offset such issues.

4. Meshforce M7

  • Best for: Performance
  • Key Features: High performance and seamless roaming. Great security options. Quick set up. Versatile design.
  • Coverage: 2000 square feet
  • Dimensions: 5.3 in x 4.4 in x 5.3 in
  • Voltage: 240 volts

If you need an extremely reliable Wi-Fi signal when using Xfinity, the Meshforce M7 is likely your best extender option. The seamless box utilizes Tri-Band WiFi that automatically connects to the fastest and least-crowded network. That then leads to the highest possible speeds.

In addition, the extender comes with seamless roaming as well as some of the best security options on the market. Not only does it have advanced security protocol, but a built-in firewall as well.

That being said, the companion app could be a bit more reliable. It’s usable and gets the job done, but the design and UI aren’t as streamlined as they could be. Everything else works exactly as advertised.

5. Cisco Business 140AC Starter Kit

  • Best for: Speed
  • Key Features: High coverage rate. Quick set up through mobile management tool. Mix and match capabilities. Reliable.
  • Coverage: 3000 square feet
  • Dimensions: 6 x 6 x 1.3 in
  • Memory: 512 MB Flash 1 GB RAM

Coming with 2 mesh extenders, the Cisco Business Starter Kit is a strong item that boosts your signal over an impressive 3000 square feet. That coverage, combined with the lightning quick setup, makes it a premium device for people who need a good network.

It fixes any dead point you might have and is extremely flexible. You can mix and match up to 25 additional Cisco Business access points. That versatility is incredibly useful, especially if you have a larger space.

The biggest downside to the product is that it is one of the more expensive options on the market, especially when compared to other extenders. 

6. Rockspace Wi-Fi Extender 

  • Best for: Affordability
  • Key Features: Streamlined design. Easy setup and strong connectivity. Wide compatibility. Stable connection.
  • Coverage: 1300 square feet
  • Dimensions: 3.15 x 2.95 x 2.95 inches
  • Transfer Rate: 1200 megabits per second

The Rockspace Wi-Fi Extender provides you with 360 degree full signal coverage, amazing speed, and premium transfer rate, all without breaking the bank. It’s an affordable way to bring a strong signal to your home or office.

While this is much cheaper than other pricey extenders, it doesn’t lose any key attributes. It comes with dual external 2 antennas, supports up to 1200 megabits per second, and has a multi-secure connection. There’s a 2 in 1 connection mode.

This is an incredibly reliable extender, but it does have a smaller range when compared to the other items on this list. If you have a smaller area that won’t be a big deal, but expect some issues when pushing this to its absolute limits.

How to Choose a WiFi Extender for Comcast Xfinity


An initial consideration with any WiFi extender is how much additional coverage it offers. You want to make sure that the extender you purchase will be able to make a difference in increasing your internet signal and providing reliable speeds throughout the coverage area.

You should know the square footage of the home or building you want to get an extender for before making a purchase.

Once you know your square footage, you can cross-reference that with the capabilities offered by the extender.

Most extenders will offer at least up to an additional 1000 square feet of coverage, but it’s always a good idea to know your exact needs before spending the money on a device.


Speed is another important consideration when choosing a WiFi extender. Part of the reason you may want an extender in the first place is to get increased internet speeds throughout your coverage area.

As you get farther away from your Xfinity router, the speed of the WiFi will inherently go down. A WiFi extender not only provides signal in areas that don’t have it, but it also boosts speed in areas further from the router.

Different extenders have different speed capabilities. If you want extremely fast coverage, look for an option that has a speed of 1000mps or more.

If you don’t have that fast of internet to begin with, then you won’t need to get an extender with as much speed.

Faster speed is always great, but you should also realize that sometimes, even with an extender, you will see decreased speeds the farther you are from the WiFi source.


As with just about any purchase, cost is a consideration. Luckily, most WiFi extenders are pretty affordable. A smaller, stand-alone unit is going to be the cheapest option.

Versions that offer higher speeds or multiple extenders in a series will be more expensive.

You don’t need to spend a crazy amount of money to get good WiFi coverage, but if you want higher speeds and complete coverage, you will have to shell out a bit more.

Some Other Tips

When you’re trying to extend your WiFi coverage, you need to take into account where your router is located. You don’t want it to be hidden by a couch or directly behind thick walls that can potentially block the signal.

An extender will increase the effectiveness of your router’s signal, but the more signal it puts out in the first place, the better you will be able to extend upon what already exists. Check out this video on where to place your router.

Final Thoughts

Having a good signal is important. It does not matter if you’re watching movies, having a video call, or need to get important work done, a strong WiFi signal is a must-have for a bigger building or property. It can help you get the coverage you need without spending a bunch of money.

All of the options listed here will allow you to easily extend your Xfinity router’s range within minutes and they’ll give you great results for years to come.
