Best WiFi Extender 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.

Quick Summary

  • The Netgear WiFi Range Extender EX3700 is a great option for boosting the coverage of your Xfinity WiFi service. This is a small-but powerful-extender that’s also affordable and effective.
  • Another good option is the TP-Link AC1750 WiFi Extender. This will provide you with an instant increase in coverage and make sure that nearly all areas of your home receive proper service.
  • If you have long-range extension needs, then you need a model that can put out some serious signals. The SE TEK Superboost WiFi Extender is sure to provide you with the coverage needed in longer-range situations.

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: What to Consider


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 provide 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.

Useful Tips & Resources

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.

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.
