What Makes a WiFi Extender Great For Use With Spectrum?

Curious about how we’ve narrowed down our decision for the best WiFi extenders to use with Spectrum? Let’s take a look at what makes a WiFi extender great for use with Spectrum.

Compatibility With Spectrum

To use a WiFi extender with Spectrum, it’s important to make sure it’s compatible with Spectrum and your other devices. Technically speaking, any WiFi extender should be compatible with Spectrum.

However, you also need to make sure it’s compatible with your router and the WiFi devices you wish to connect it to, including laptops, PCs, and the large variety of available smart products. Make sure you check the specs on both the WiFi extender and your WiFi products before proceeding with the purchase.

Range/Signal Coverage

With Spectrum being known for potentially poor signal coverage, it’s important to make sure that your chosen WiFi extender can improve your range as far as you need it. After all, the whole point of purchasing a WiFi extender is increasing your range, right? When narrowing down your search for the perfect WiFi extender, make sure that you take the range into account so you can make sure your whole house is covered.

Single or Dual Band Frequency

You’ll notice that the majority of the WiFi extenders we’ve included in this article include the option of a dual-band. Usually, purchasing a WiFi extender with a dual-band spectrum is most ideal, but it does depend on what you wish to use your WiFi for. If you primarily use your WiFi for surfing the net and sending emails, then a dual-band frequency may be fine for you.

However, if you often stream HD media and participate in hardcore gaming sessions, then a dual-band frequency will be best for you. A dual-band frequency allows you to turn up your frequency depending on your WiFi use, offering a higher data transfer rate for applications that use up a ton of data.

Price & Budget

When purchasing any product, it’s important to consider your price range. You’ll still be able to purchase a WiFi extender that’s compatible with Spectrum on a lower budget; however, you’ll need to beware of poor quality WiFi extenders. We’ve included some budget-friendly options in our guide that have still proven to be high-quality.

What Does a WiFi Extender Do?

When it comes down to it, what does a WiFi extender do, and do you need one? Let’s take a look at why a WiFi extender is a popular purchase.

Improves Range

A WiFi extender improves the range of your WiFi signal, so you can reach every nook, cranny, and of course, workspace in your household. Purchasing a WiFi extender will allow you to work from anywhere you may please within your own house (as long as you purchase a product with the correct range for your space).

Eliminates Dead Zones

Dead zones are a common issue for WiFi routers with low range. The perfect solution? Purchasing a WiFi extender! By improving range, you’ll virtually be eliminating any dead zones in your household.

Improves Signal

A WiFi extender improves your signal strength, which in turn may increase your upload/download speed. The speed you receive is only as good as your WiFi extender, so it’s important to pay attention to both frequency and speed when choosing your extender.

How to Boost Your Spectrum WiFi Signal

Looking for ways to boost your Spectrum WiFi signal? Let’s take a look at some easy fixes that may help improve your WiFi signal.

Strategic Placement of Modem and WiFi Router

When you set up your modem and WiFi router, it’s important to consider where you use your WiFi most. If you use your WiFi equally throughout the house, then it’s helpful to set up your modem and router as close to the middle of your home as you can. If you primarily use your WiFi in one area of the house, such as a media room, this is a good place to set up these products.

Using a WiFi Extender

Of course, using a WiFi extender is one of the best ways to boost your Spectrum WiFi signal! By using a WiFi extender, placement of your modem and WiFi router is not nearly as important, with your extender helping to cover every area of your household.

Avoid Signal Blockers

Whether or not you’re using a WiFi extender, it’s important to avoid signal blockers. This means not placing these items in a closet or cabinet, not placing your router on the floor or low to the ground and not placing your router next to windows.


While it can be challenging to purchase a WiFi extender that works optimally with Spectrum connections, we have narrowed down the best options on the market that specifically work well with this provider. The WiFi extenders we’ve listed increase the strength of the wireless signal in your coverage area, eliminating those inconvenient dead zones that sometimes come along with a Spectrum provider.
