Factors To Consider When Looking For The Best WiFi Extender For Xfinity

Xfinity Compatible WiFi Extenders

If you are looking for a range extender, it means that your current router is not able to deliver enough range for all your devices.

And since you are purchasing the WiFi extender to get extra coverage, ensure that you check the available coverage of the extender to know more about its performance.

Usually, coverage is indicated for each extender in terms of square feet, representing the area where your devices will maintain a strong connection.

Generally, the coverage will be advertised on the buying page of the extender, but you should note that some of the coverage advertised can be a bit excessive while others are underestimated.

On average, the extenders can reach between 70% to 120% of what is advertised.

Additionally, the coverage depends on your router as better routers lead to stronger signals. Be careful not to place the extender far or close to the router as this will lead to worse coverage and speed.

WiFi Speed (WiFi 5 vs WiFi 6)

Today, there are two main types of WiFi standards, WiFi 6 and WiFi 5. The difference is WiFi 6 is more secure, can handle more devices, and is generally faster while WiFi 5 is normally cheaper.

When buying a WiFi extender for Xfinity, ensure that you match the WiFi standard of your router because it is not necessary to get an extender with WiFi 6 technology if your router supports WiFi 5 and vice versa.

If you have an Xfinity gateway, you are likely using WiFi 6 with an internet plan which is more than 200 Mbps. But if the plan is less than 200 Mbps, the WiFi standard is likely WiFi 5.

Check the bottom of the device to be sure. If it says 802.11ax, you have WiFi 6, and if it says 802.11ac, you have WiFi 5.  

Number Of Connected Devices

Similar to WiFi routers, WiFi extenders can also connect to only a certain number of devices on the network simultaneously.

Additionally, when the extender is connected to more devices than it can handle, the available network speed and overall performance reduce for all connected devices. Therefore, get an extender that can handle the number of devices that you have.

For instance, if you want to connect one or two devices, there is no need to worry about the number of connections the extender can have.

However, if you want to connect multiple smart devices, you should check the number of connections offered by the extender.

WiFi Extender vs Mesh WiFi System

Both WiFi extenders and Mesh WiFi increase the performance and coverage of networks. However, the key difference is that Mesh networks do not use a central router to connect every device while WiFi extenders re-broadcast an existing signal.

If you want to extend your coverage to less than 60 feet and have an Xfinity Blast Pro plan or less (600 Mbps), a WiFi extender is better.

On the other hand, a Mesh WiFi system is suitable if you want to extend your WiFi to more than 60 feet and you are subscribed to an Xfinity Extreme Pro Plan or more (900 Mbps).

How To Setup A WiFi Extender With Xfinity

Xfinity Extender Setup

  • To start the setup, download the application on your smartphone.
  • Activate the extender and establish the connection with its Wi-Fi using your mobile device.
  • Then launch the manufacturer’s application and follow the directions provided.
  • You should have the connection in less than 2 minutes.

Alternatively, you have the option of using the WPS button.

  • Press the WPS button on both the extender and the router. Repeat this procedure for each band supported by your extender and router.
  • Subsequently, relocate the extender to a suitable location that is neither overly close nor too distant from the router.
  • Once the connection is established, an indicator light on the extender will be green. The light remains green for a stable connection and turns red if the quality of the connection is poor. If the light turns red, consider moving it nearer to the router.

Xfinity WiFi Extender FAQs

Can I Use A WiFi Extender/Repeater With My Xfinity Router?

Yes, there is no compatibility factor between a WiFi extender and a Xfinity internet, but there is one with some routers.

Certain extenders are specifically designed to pair and function exclusively with specific routers.

What Is The Difference Between A WiFi Extender And A WiFi Booster?

WiFi extenders function as devices that expand the existing WiFi network in situations where the signal weakens, effectively carrying signals over extended distances. They are set up between the router and the connected device.

On the other hand, a WiFi booster is integrated into the router itself and serves as an antenna to enhance its potency.

Does A Mesh WiFi System Offer Better Speeds Than A WiFi Extender

Yes. If you reside in a more spacious home or require consistent and faster speeds exceeding 100 Mbps over extended distances, it is beneficial to consider upgrading to a mesh router that comes with its own satellite devices for extending the range.

Today, plenty of options are available and nearly all of them would probably surpass the performance of a standalone router combined with a plug-in range extender.

Are All WiFi Extenders Compatible With Xfinity?

Every WiFi extender is compatible with Xfinity, however, not all WiFi extenders work with every router.

Does A WiFi Extender Slow Down Internet Speed?

No. Whenever the internet passes through a secondary device such as an extender, there is a certain loss in speed.

This implies that the extender can never match the speed of your router. Nevertheless, using an extender will still result in a higher average internet connection speed within your home.

Final Words

If you’re facing range issues with your router, consider purchasing a WiFi extender to ensure full coverage throughout your home, eliminating any dead zones.

If you are not sure which extender to get, our top pick for the best WiFi extender for Xfinity is the TP-Link RE650. With this extender, you can easily send high-performance WiFi throughout your home to remove any lag and dead spots.

This extender’s Wave 2 WiFi technology comes with 256 QAM and 4-Stream, which creates ultra-fast AC2600 internet speed for 4K streaming and seamless gaming in any room.
