Keep reading to learn them.

Top 7 Best WiFi Extenders for Xfinity

Here’s a rundown of the best WiFi extenders for Xfinity

01. TP-Link RE650 - Best Extenders

TP-Link RE650 Best Overall

Coverage: ≈ 70 feet
Maximum speed (Wi-Fi): 332.58 Mbps
Separate network: Yes (not with TP-Link routers)
Suggestion: Extreme Pro or below (900 Mbps)
Wireless standard: Wi-Fi 5 AC2600
Warranty: 3 years



  • Quickly
  • Excellent range
  • 3-year warranty
  • Separate network

The TP-Link RE650 is your best option if you require coverage for a sizable Wi-Fi dead area.

Its Wi-Fi signal tested at 332.85 Mbps from five feet away, 276.40 Mbps from twenty-five feet, and 202.44 Mbps from forty feet.

For a family of five or more to stream 4K movies, the surprisingly high performance of a Wi-Fi 5 extension should be sufficient.

Individual networks vanish when using Ethernet to connect to the router, which TP-Link refers to as access point mode, and it becomes quicker.

Instead of 332.85 Mbps, it achieved 657.32 Mbps from a distance of 5 feet—a sufficient speed for 15.4k streaming.

Now is where the RE650 sets itself apart – the range.

The extender network had the strongest signal of all the extenders I tested in any place I measured while connected to the router through Wi-Fi.

And we calculate that its range is around 70 feet. Even in the most impressive mansions, this will span an entire floor.

The signal was substantially stronger when connected to the Ethernet router and could be seen for around 80 feet.

When a signal is powerful enough, it may surpass multiple routers.

We used the Teather app in less than two minutes after a simple setup that took only a few minutes.

If you don’t have a TP-Link router with OneMesh, the RE650 will provide you with a separate network, which is one disadvantage. This demands network switching as you move about.

In general, TP-Link RE650 is the best option if you want wide coverage. Remember that this (unlike OneMesh) establishes a distinct network from your router.

02. Netgear EAX80 - Best Performer

Netgear EAX80 Best Performer

Coverage: ≈ 65 feet
Maximum speed (Wi-Fi): 437.34 Mbps
Separate Network: No
Suggestion: Any Xfinity Internet plan
Wireless standard: Wi-Fi 6 AX6000
Warranty: 1 year



  • Too fast
  • Good range
  • Same network
  • Expensive
  • Not as easy to set up

The Netgear EAX80 is the fastest extender we’ve tested and will work for any Xfinity plan.

In testing, it reached 437.39 Mbps from 5 feet and 365.72 Mbps from 15 feet using the 5 GHz bands.

However, walking another 10 to 25 feet from the extender, speeds dropped to 227.59 Mbps.

Performance is still excellent for being the best Wi-Fi extender.

To put it in perspective, you can download an HD movie (5 GB) in 1 minute 38 seconds.

With an Ethernet connection to the router, the EAX80’s speed increased to 811.59 Mbps.

A throughput so fast that you can download anything in just a few minutes. (Yes, it’s fast).

The EAX80’s signal was also good, receiving a powerful signal where we tested it. It can reach up to about 65 feet, which is slightly higher than the TP-Link RE605X.

The Wi-Fi extender is enough to cover an entire floor and a little more.

The EAX80’s lack of a second network is yet another great feature. This implies that the network of your router is only strengthened.

So you don’t have to switch networks while moving around your home.

The EAX80, however, is not all sunshine and roses. It has some imperfections.

The first is its price, which is relatively high for a Wi-Fi extender. And at this price point, it might be best to buy a new router or mesh system instead.

Furthermore, the setup of the EAX80 was more challenging than other devices. And switching it between Ethernet mode and Wi-Fi mode requires a reset of the entire device to work.

The Netgear Nighthawk EAX80 is an all-around high performer with excellent speed and range. But the cost of its performance is tremendous.


03. TP-Link RE605X – Best Wi-Fi 6

TP-Link RE605X Best Wi-Fi 6

Coverage: ≈ 60 feet
Maximum speed (Wi-Fi): 346.35 Mbps
Separate network: Yes (not with TP-Link routers)
Suggestion: Extreme Pro or below (900 Mbps)
Wireless standard: Wi-Fi 6 AX1800
Warranty: 3 years



  • Quickly
  • Easy setup
  • 3-year warranty
  • Separate network

A reliable Wi-Fi extender with the Xfinity Extreme Pro plan or below is the TP-Link RE605X.

Using the 5 GHz band, it tested at 346.35 Mbps at 5 feet, 268.04 at 15 feet, and 257.04 at 25 feet.

These impressive results are sufficient for ten simultaneous 4K movie streaming.

When connected to an Ethernet router, its speed practically doubles, up to 674.53 Mbps at a distance of 5 feet.

This enables quick downloads of the majority of items.

The RE605X also had exceptional range performance. There was a strong signal everywhere, so we measured it.

It will have a maximum height of roughly 60 feet. This makes it possible for it to cover the whole floor.

We tested the extension with a powerful router (ASUS RT-AX88U).

And compared to when it was linked to a less powerful router, its performance was obviously better.

Additionally, the setup was quite simple. Launch the Tether app, connect to its Wi-Fi, and then follow the directions. In less than 60 seconds, we were standing.

Even yet, this was not the first time we had put up an extension.

If you need a TP-Link router with OneMesh, the RE605X will have a separate network, which is its biggest drawback. Consequently, if you roam at home, you must manually connect to it.

It won’t have a separate network (if you connect to the router using Ethernet).

So think about getting one of the Netgear extenders if you have an Xfinity gateway and want to avoid using various networks.

The TP-Link RE605X is a good solution all around. Delivering excellent performance, coverage, and setup at a reasonable cost.

If your router is not OneMesh compatible, it results in the creation of distinct networks.

04. Netgear EX7300 - Runner up

Netgear EX7300 Runner Up

Coverage: ≈ 60 feet
Maximum speed (Wi-Fi): 324.58 Mbps
Separate Network: No
Suggestion: Extreme Pro or below (900 Mbps)
Wireless standard: Wi-Fi 5 AC2200
Warranty: 1 year



  • Quickly
  • Collective network
  • Setup isn’t as easy as it sounds

With Xfinity’s Extreme Pro or below (900 Mbps), the Netgear EX7300 is a reliable all-around choice.

Using the 5 GHz band, it achieved speeds of 254.25 Mbps at 25 feet, 239.65 Mbps at 15 feet, and 324.58 Mbps at 5 feet.

And yes, it got faster at 25 feet than at 15 feet – to our surprise.

These speeds are solid and good enough for most household internet needs.

Connecting it to the router with Ethernet significantly improved its performance, more than doubling the throughput – to 651.58 Mbps.

A speed so fast that it can download Call of Duty: Infinite Warfare (101 GB) in 22 minutes and 11 seconds.

Remember that we used an ASUS RT-AX88U router with a gigabit internet plan to evaluate these extenders. If you’re using a weak router, it will also make them operate better.

It had a reasonable range of around 60 feet, nothing unusual. There should be plenty for a floor if the extension is close to the center.

The mesh feature of the EX7300 combines with the network of your router.

As a result, you can move throughout the house without changing networks.

The EX7300’s setup was perfect. The connection to the router was problematic, but after a hard extender reset, it was successful.

The Netgear EX7300 is a reliable all-around extender with respectable performance and range. It has a network all by itself.

05. Linksys RE7000 - Best Value

Linksys RE7000 Best Value

Coverage: ≈ 60 feet
Max Speed (Wi-Fi): 320.83
Separate network: Yes
Suggestion: Extreme Pro or below (900 Mbps)
Wireless standard: Wi-Fi 5 AC1900
Warranty: 3 years



  • Quickly
  • Easy to set up
  • 3-year warranty
  • Always separate networks

The Linksys RE7000 is another all-in-one option with a little more.

It scored 320.83 Mbps from 5 feet and 267.2 from 25 feet during testing, using the 5 GHz band.

Good results, which are enough for about 5-10 4k streams.

When using Ethernet to connect to the best router, speeds increased, but not as much as expected – getting 519.73 Mbps from 5 feet.

It’s still fast and sufficient for a home with heavy internet usage and many smart devices.

However, if you want to use Ethernet to connect it to your router, I wouldn’t advise purchasing the RE7000.

This is due to the RE7000’s permanent independent network. You won’t get a distinct network for most other extenders even if you utilize Ethernet or Ethernet mode.

The extender has an average range of roughly 60 feet. This should be sufficient to offer Wi-Fi for a whole floor.

It was simple to set up the RE7000; all I had to do was connect to its Wi-Fi, open the Linksys app, and follow the on-screen directions.

Ultimately, it took roughly 10 minutes because it took longer than usual to load.

The Linksys RE7000 is an excellent deal overall. It enables you to perform well for the price.

Don’t buy it if you want to connect your extension to the router via Ethernet. Some of the other alternatives are suitable for that.

Check the current price.

06. TP-Link RE315 – Budget-friendly

TP-Link RE315 Budget Friendly

Coverage: ≈ 60 feet
Max Speed (Wi-Fi): 187.61
Separate network: Yes (not with TP-Link routers)
Suggestion: Performance Pro or below (300 Mbps)
Wireless standard: Wi-Fi 5 AC1200
Warranty: 3 years



  • Cheap
  • Easy to set up
  • 3-year warranty
  • Quite slow
  • Separate network

TP-Link RE315 is a solid cheap extender with Performance Pro or below (300 Mbps).

It tested at an average speed of 122.62 Mbps at 25 feet, 165.21 Mbps at 15 feet, and 187.61 Mbps at 5 feet.

Although not very impressive, these outcomes are adequate for four 4K streams.

The speed is typically increased when using Ethernet to connect to a router, reaching 302.51 Mbps.

A family of roughly five people can utilize the internet without incident with a good outcome.

We were delighted by the RE315’s range, which put it on a level with pricier models.

It needs to extend around 60 feet. For the majority of the dead places you have, this is sufficient.

If you don’t have a TP-Link router, OneMesh has a separate network, much like other TP-Link extenders. But every other device in this price bracket is as well. Thus, it is fine.

Additionally, the setup was pretty simple. In less than a minute, we were operational.

TP-Link RE315 is a high-speed, excellent, budget-friendly internet plan without a router.

07. Netgear EX3700 – Most budget-friendly

Netgear EX3700 Most Budget Friendly

Coverage: ≈ 50 feet
Maximum speed (Wi-Fi): 138.72 Mbps
Separate network: Yes
Suggestion: Performance Starter or below (100 Mbps)
Wireless standard: Wi-Fi 5 AC750
Warranty: 1 year



  • Professional
  • Cheap
  • Easy to set up
  • Slow
  • Separate network

The most simple extender on our list is the Netgear EX7300. You’ll get the best Xfinity performance with a Starter plan or below (100 Mbps).

During testing, its Wi-Fi scored 138.72 Mbps from 5 feet, 120.89 from 25 feet, and 55.93 from 40 feet.

The last result is in the 2.4 GHz range, whereas the previous two findings are in the 5 GHz spectrum. Learn more about the distinctions between the bands here.

The results are respectable, but given the budget, they may be faster regarding raw speed. 3–4 individuals may use it.

It received 216.32 Mbps as an access point (connected to the router via Ethernet). An acceptable quantity sufficient for 4K streaming

We first notice that we are in the affordable range when it is inside its content. It monitors signal strength at a lower level than other premium models.

Our best guess puts its range at about 50 feet. This will adequately cover a sizable area of your house. But it probably falls short if you have a big place and want coverage for an entire floor.

Additionally, the primary router’s network is created separately by the EX7300. This implies that if you move about your home, you must alter your network.

The extension was simple to set up, though. It successfully establishes a connection to the router.

The Netgear EX7300 is a sluggish internet plan and a modest Wi-Fi dead spot for you.

Do you need a Wi-Fi extender?

If your Wi-Fi router well serves your home and you only need to strengthen the signal in one room or part of your home, a Wi-Fi extender can be the perfect solution.

In light of this, you might relocate your router to a hub.

Consider purchasing your own devices if the Xfinity Gateway’s performance isn’t to your liking.

You won’t require an extender if you receive a couple more premiums.

Buying Guide for Comcast Xfinity WiFi Extenders

Before purchasing a Comcast Xfinity WiFi extender/repeater, consider this. See our Wi-Fi extender buying guide for more comprehensive information.

Match the brand

Most Wi-Fi repeaters and extenders are compatible with all types of routers. The brand of your router should be matched, though.

This is due to two factors. First, it will be less probable for rival brands to cause problems.

Although we tried the following extenders with routers from different companies, They all contributed.

The second reason is that if you own a TP-Link router and a TP-Link extension, certain manufacturers, like TP-Link, will let you build a single network.

As a result, you can move throughout your home without changing networks.

You won’t be able to match the brand if you utilize the Xfinity default gateway. But it’s something to think about if you have your gadget.

Wi-Fi 5 vs. Wi-Fi 6


Wi-Fi 5 and 6 are the two main Wi-Fi protocols currently in use.

The difference is that Wi-Fi 6 is more secure, capable of supporting more devices, and typically quicker. Although Wi-Fi 5 is inexpensive and frequent enough.

We advise choosing a Wi-Fi extender for Xfinity that is compatible with the Wi-Fi standard of your router.

If your router is Wi-Fi 5, you do not need a Wi-Fi 6 extender, and vice versa. To ensure its future, you may purchase a Wi-Fi 6 extension.

If you have an internet service with speed greater than 200 Mbps and an Xfinity gateway, you probably have Wi-Fi 6.

And you most likely have Wi-Fi 5 if your speed is less than 200 Mbps.

Verify the device’s bottom to make sure. You have Wi-Fi 5 if it says 802.11ac; Wi-Fi 6 if it says 802.11ax.

For further details, see our post comparing Wi-Fi 5 to Wi-Fi 6.

What if my router is Wi-Fi 4?


Instead of purchasing an extender, if you have a Wi-Fi 4 router, it’s time to replace it.

Because upgrading from a Wi-Fi 4 router will disappear your Wi-Fi dead spots.

Check out our articles on Xfinity routers for some great choices.

Tri-Band vs. Dual-Band


The 2.4 GHz band has a more excellent range than the 5 GHz band in a dual-band extender. The 5 GHz band is quicker.

There will be two 5 GHz bands and one 2.4 GHz band in a tri-band extender.

This will enhance the extra 5 GHz band extender’s bandwidth without increasing the device’s top speed.

Consider adding a third band if you have multiple intelligent gadgets and Xfinity’s gigabit service.

But most people won’t need it. A mesh network will also work better with a gigabit plan and several intelligent gadgets.

None of the extenders on the list above are tri-band. However, the Netgear X6S EX8000 AC3000 is a good option if you want one.

For more information, see our article on dual-band vs. tri-band.



The extender/repeater will often promote its coverage on the purchasing page.

However, based on our tests, it is reliable. While some are overstated and others are understated.

As promised, the extenders we tested often achieved between 70% and 120%.

Your router’s performance will impact coverage since a better router enables the extender to give a stronger signal. It results in an amplified signal that is stronger.

Additionally, be cautious while deciding whether to place the extender near or far from the router. Both produce inadequate speed and coverage.

Ethernet or WiFi connection to the router


Nowadays, the majority of Wi-Fi boosters feature two modes.

I may use an access point (Wi-Fi extender) connected to the router’s Wi-Fi or an Ethernet wire to connect to it.

Since everyone on the list holds both roles, I’ve used the words interchangeably throughout this article. But you should be aware of the differences in terminology.

So, which mode is best?


We experienced nearly two times the speed and a 20% increase in coverage while using Ethernet. Most gadgets won’t require a second network because it doesn’t generate one, eliminating the need to switch while moving about the house.

But there are times when running Ethernet cables throughout the house makes sense. As a result, it relies on your situation and your goals.

However, if you have Xfinity’s gigabit plan, employing Ethernet mode or investing in a mesh network is the only way to get close to fulfilling the full advantages of the mission.

Additionally available are powerline adapters. Utilizing the electrical wiring in your home, this device. The house’s extensive Ethernet wiring is being taken out.

Wi-Fi Repeater/Extender vs. Mesh WiFi


Wi-Fi Booster and Mesh Wi-Fi both improve network performance and coverage.

A Wi-Fi repeater only rebroadcasts an already-existing signal, which is the main difference. Mesh networks connect all of the devices without the need for a central router.

A Wi-Fi repeater or extender should extend your coverage to less than 60 feet and has an Xfinity Blast Pro plan or below (600 Mbps).

However, a mesh system is recommended to extend your Wi-Fi beyond 60 feet and have an Xfinity Extreme Pro plan or above (900 Mbps).

Of course, this is only our opinion and is not binding.

How to set up an extender with Xfinity


First, download the brand’s app to set up an extender.

After that, turn it on and use your smartphone to connect to its Wi-Fi. Then open the brand’s app and follow the instructions.

Usually, it takes less than two minutes to get started.

The extender’s WPS button can also be used. Your router and extension will connect after you press this.

(On most Xfinity gateways, the WPS button is just above the Ethernet port)

Suppose you want to use an Ethernet connection between devices. You should set it up using a computer for the Netgear Extender.

On a computer, you will be redirected to the setup page when you open a browser.

For more information, see our article on how to set up a Wi-Fi repeater.

What about Xfinity xFi pods?


If you rent your gateway from Xfinity, consider getting an Xfinity xFi Pod. This Wi-Fi extender is specially designed for xFi gateways.

Just note that this is an AC3000 extender, which means it’s Wi-Fi 5 and thus slower than the Wi-Fi 6 options in this article.

It does, however, offer free-roaming, or in other words, it has a single network, So you don’t have to switch networks while moving around your home.

Remember, you only get this if you rent an Xfinity xFi Gateway. This won’t work if you have your router.

You can get an xFi pod here.

Xfinity Internet Plan


Here are Xfinity’s internet plans and which Wi-Fi boosters I recommend.

Internet plan Wi-Fi booster

Performance (100 Mbps)                            TP-Link RE315 AC1200
Performance Pro (300 Mbps)                     Linksys RE7000 AC1900

Gigabit (1200 Mbps)                                     Netgear EAX80 AX6000


These are some frequently asked questions about and best WiFi extenders for Xfinity.

What is the best Wi-Fi extender for Xfinity?


After much testing and consideration, we’ve concluded that the best Wi-Fi extender for Xfinity is the TP-Link RE650.

To see some other good options, see the article above.

Does a Wi-Fi extender slow down the internet?


No, it doesn’t.

Some speed is lost whenever the Internet passes through a secondary device such as an extender.

However, this implies that the extension will take longer than your router. You can still obtain a fast, typical internet connection at home using an attachment.

Where do I install the Wi-Fi extender?


Between your router and the Wi-Fi dead zone, place the extender. The extender will typically let you know when you are too near to or too distant from the router.

Our verdict


According to our analysis and testing, the TP-Link RE650 is the top Wi-Fi extender for Xfinity.

Remember that if it doesn’t connect to a TP-Link router with OneMesh, it creates a separate network despite being quick, simple to set up, and inexpensive.
