#1. TP-Link AC2600 WiFi Extender Dual Band WiFi Range Extender

TP-Link AC2600 WiFi Extender


Whether you are new to the Internet game or you’ve been around the industry for years, you’ve likely heard of TP-Link. This is because, over the years, they’ve grown to be one of the most recognized and well-respected names in the game. And, you’ll understand why this is the case when you see everything that the AC2600 WiFi Extender offers.

While there are tons of extenders currently available on the market, it’ll be extremely hard to find one that offers everything as much quality and dependability as the AC2600. Just start by taking a look at the quad antenna design.

  • Quad Antenna Design

When you first lay eyes on the AC2600, you are going to think you are looking at something from space. Something alien-made. And, this is because it is extremely futuristic, with futuristic capabilities. The quad antenna design might be an odd-looking one, but it boosts your Wi-Fi signal coverage by phenomenal lengths.

The four high-powered antennas minimize dead spots in the home or office while also creating strong, reliable Wi-Fi connections. With these types of capabilities and extensions, you’ll literally be able to connect your devices in the furthest reaches of your home or office.

Need to go through double-cemented walls? Maybe you are trying to see a signal through drywall and R-8 insulation. Whatever the situation, it won’t be an issue with the quad antenna design.

  • Beamforming Technology

If you thought the quad antenna design was impressive, you haven’t seen anything yet. While the quad antenna design minimizes dead spots and extends your overall coverage, the beamforming technology actually directs the signal where they need to go. That’s right, instead of just sending the signal out blindly, this technology will direct it to the device or devices in need of Wi-Fi.

The device does this by detecting the direction of the devices that need connection and focuses that wireless signal towards them, helping strengthen your home or office’s overall Wi-Fi performance.

  • Take Advantage Of MU-MIMO

With the number of unique devices with Internet capabilities and the affordability of these devices, more and more people are purchasing more and more devices. For instance, your kids likely have phones with Internet capabilities as well as tablets with the same connection capabilities. Maybe even a watch or smart camera with Internet capabilities.

Whatever the situation and the type of devices, you won’t have to worry when you make an investment in the AC2600 Extender. This extender by TP-Link offers wave 2 technology that allows the extender to connect multiple devices to the same bands.

And, what’s even more impressive is, it does all of this without even sacrificing or compromising the strength and power of the signal. All devices will receive the same quality and dependable connections with the same speeds and strength.

  • Intelligent Processing Engine

Going back to the over scenario, this is also another area where the Intelligent processing engine technology comes in handy. The AC2600 is also equipped with what is known as Intelligent processing engine technology.

This type of technology was specifically designed to help the extender balance the demands of all the connected devices. This helps keep the signal fast and smooth across all connections and bands. The engine sends Wi-Fi traffic to dedicated processors, freeing up valuable resources so that the powerful processors can handle the request of the connection requirements.

While the processors in the AC2600 are extremely powerful and reliable, any processor will bog down if you start loading it down with tons of tasks.


  • Beamforming technology directs signals
  • Quad antenna design maximizes signal coverage
  • MU-MIMO helps keeps the signal smooth and balanced
  • Intelligent Processing Engine technology


  • Only an extender
  • Doesn’t work as a modem or router on its own. It Will have to be paired with an additional modem or router

Overall Assessment

You can clearly see that the AC2600 has pretty much that everything an extender needs. In fact, it offers more, with one downside. And that downside is, you’ll also need another modem or router to pair the device with. This is only an extender and only capable of extending your Wi-Fi signal, but it does an excellent job of what it does!

#2. TP-Link Deco Mesh Whole-Home Coverage WiFi Extender

TP-Link Deco Mesh WiFi System(Deco M5)


After seeing everything that the TP-Link AC2600 had to offer is it really a huge surprise to see another TP-Link on the list? For those that are familiar with the Internet industry it likely isn’t. That being said, users need to know that the AC2600 and Deco Mesh systems are nothing alike.

While being similar devices and being developed by the same manufacturer for the same purposes, they have so much more to offer in different areas. To start out, the Deco Mesh System here is a whole home or office system, with three different pieces.

  • The Different Extenders

With three different mesh devices, users will literally be able to immerse their entire homes or offices with powerful Wi-Fi connections. This will be the case, regardless of the shape, size, or design of the home or office. And, this is all because of the three system design. These three devices work in conjunction to provide maximum coverage of nearly 6,000 square feet.

  • Alexa Capabilities

Speaking of ease of use, it doesn’t get any easier than simply telling your device what to do. And, that’s exactly what you’ll be able to do when you make the smart investment in the mesh system.

With the additional purchase of the Alexas system, users will be able to control and manage their network using their voice. The additional purchase will be more than well worth the extra investment.

Wi-Fi is pretty much essential or necessary for many today. The only problem is, it is also risky. Luckily, TP-Link helps minimize those risks with built-in anti-virus protection. That’s right, this mesh system comes with built-in anti-virus protection. Every one of the three devices will offer anti-virus protection for your devices when you are browsing the Internet.

Instead, you’ll need to consider the device’s pros and cons too. You’ll also want to research the factors found below.

  • Compatibility

You’ll want to find the best WiFi extender Xfinity offers. If you’re working with Comcast, you may want to purchase Xfinity Pods. This is the company’s Wi-Fi extender. Pods help expand your WiFi coverage so you can take care of the dead zones in your home. However, Xfinity Pods might not be the best choice because they’re expensive.

And, you might get better features with one of the others. Either way, you need to go above and beyond to make sure that your Wi-Fi extender is compatible with Xfinity. If you have a different Internet service provider, you’ll need to do the same.

Make sure your extender will work fluidly with your ISP or you’ll regret purchasing it.

  • Antennas

Ultimately, the purpose of the Wi-Fi extender is to expand your home network. With that being said, you’ll want to make sure that your extender is going to achieve this goal. To do that, you’ll need a Wi-Fi extender that features multiple antennas. One antenna is good. Two antennas are even better.

The antennas are used to ensure that you’ll be able to receive a strong signal. And, it will help send the signal further. With this in mind, you should research the extender and make sure it has multiple antennas. This will help ensure that you get the best results.

  • Size & Power

Most Wi-Fi extenders need to be plugged into a power outlet. This can create problems in some situations. If the Wi-Fi extender is large, it is going to cover both power outlets. This is very problematic because you won’t be able to use the outlet. How are you going to plug in your printer? You can’t because the extender covers both plugs.

This is why you need to focus on the Wi-Fi extender’s size and power requirements. Some use a power cable so it doesn’t cover the outlet. Others are smaller so the other outlet can still be used.

Try to avoid Wi-Fi extenders that cover both outlets because you might need to use the other one.

  • Range

The end goal is to expand your home’s network. If you buy a bad Wi-Fi extender, you won’t be able to accomplish this task. When purchasing a Wi-Fi extender, you need to make sure that it is going to provide plenty of extra coverage. How many square feet will the device cover? It is worth the price?

If it only covers 300 square feet, you’re likely going to be disappointed. The device won’t help since you’ll still have dead zones in your home. You need an extender that can take the signal and extend it a thousand extra feet or so.

Make sure that the added range is going to provide enough coverage to eliminate all of the dead spots in your home.

  • Speeds

Purchasing a Wi-Fi extender is similar to purchasing a Wi-Fi router. You need to make sure that the extender is going to provide excellent speeds. When you connect to the extender, your speed is going to depend solely on the Wi-Fi extender. If the extender offers 200 Mbps, you’re going to receive 200 Mbps. Even if the router offers 1200mbps, you’ll only receive 200 Mbps because you’re connected to the extender and not the router.

To avoid problems, you need a lightning-fast Wi-Fi extender. It is pertinent to choose one that can deliver excellent speeds so you can enjoy streaming videos and movies without experiencing lag.

  • Ease Of Use

When setting up your router, you likely experience a lot of issues. You’re not sure that you would be able to do it again either. Well, you have to understand that routers and extenders have a lot in common. If you have difficulty with the router, you’ll likely struggle with the extender too.

You also need to make sure that the setup process of your extender is very easy. Otherwise, you may experience so many issues that you decide to quit and give up.

FAQs on Best WiFi Extender for Xfinity Internet Service

Do WiFi Extenders Work With Xfinity?

Yes, Wi-Fi extenders are very diverse, as they are compatible with nearly every ISP. However, it is a good idea to contact your ISP prior to an initial purchase to determine Wi-Fi extender compatibility. In most cases, manufacturers utilize technologies that are compatible with the average home network ISP.

How Can I Boost My Comcast Wi-Fi Signal?

Like most ISPs, the Comcast wireless signal range is limited to a specific distance, depending on the router. The wireless router can make or break your home network. Low-tier models are not capable of delivering more than a few thousand feet. High-tier models deliver a much stronger and longer wireless signal.

As far as the Comcast wireless signal goes, it will depend on your router. The same can also be said about download speeds. A high-quality wireless router will always outperform its low-quality competitors. You are looking at a 3500-square-feet Wi-Fi signal, give or take a few for a good wireless router.

Does Comcast Provide Wi-Fi Extenders?

Comcast has a small list of network rental equipment, including the xFi Gateway combo (includes a wireless router and cable modem) and xFi Pod, which is a wireless signal extender. Comcast claims its xFi Pod is capable of extending the wireless signal generated by the xFi Gateway.

To create a mesh network utilizing the Xfinity xFi Gateway and xFi Pod, Comcast recommends installing multiple xFi throughout the home.

The xFi Pod has a white finish, AC3000 Wi-Fi capability, and a Bluetooth LE 4.0 radio. The device plugs directly into a 100-240-volt outlet and remotely connects to the xFi Gateway via Bluetooth.

Comcast Internet service does not include Wi-Fi extenders. But, the company does offer the xFi Pod Wireless Extender as a one-time purchase for $119.

Do WiFi Extenders Really Work?

With scant evidence available, consumers must rely on manufacturer claims and customer reviews for this purpose. It is believed these devices work but most are limited to only a few hundred square feet. For example, TP-Link claims its N300 TL-WA855RE WiFi Extender extends the wireless signal by 800-square feet. It also claims its AC750 RE220 Extender covers 20 devices up to 1200-square-feet.

Again, there is just not enough evidence to answer the question accurately. If you look at the thousands of customer reviews and manufacturer guarantees, the wireless extender is an effective device that extends a Wi-Fi signal by a few hundred square feet.

How Much Are Comcast WiFi Extenders?

The Comcast xFi Pod Wi-Fi Extender will set you back $119.

Do WiFi Extenders Affect Speed?

Routers generate a wireless signal that weakens as it extends into the home. The Wi-Fi extender is designed to push the wireless signal even further into the home. Since the signal is guaranteed to weaken with distance, it only makes sense that the speed would decrease as well.

Wi-Fi extenders are limited to only a few hundred square feet if you are lucky enough to get a quality brand-name It is also common knowledge that a Wi-Fi-enabled extender will impact speed by only slightly.
