    Shopping guide for the best WiFi extenders

    Last Updated April 2018

    Getting consistent WiFi reception in every part of your home can be a challenge. If you’re having trouble picking up internet in some rooms, you may wish to consider a WiFi extender.

    It’s quite common to get a robust WiFi signal of 100 Mpbs on your PC or mobile device when you are in close proximity to your base WiFi router. It’s also common to get a far weaker signal in rooms on other floors of the home — an upstairs bedroom or office, for example.

    Thick walls can block signals and neighbors with their own home networking setups can cause interference with your WiFi signal.

    A WiFi extender is similar in looks to a WiFi router, but works differently. An extender's job is to relay your WiFi's signal strength to areas with low reception.

    How does a WiFi extender work?

    A WiFi range extender rebroadcasts wireless internet signals from the base router to areas of the home where reception dips significantly below baseline. For example, if a consumer experiences a constant signal of 90 Mbps (as promised by the service provider) in the same room as the wireless router, but he receives only a fraction of that — say 10 Mbps — in a second-floor bedroom, an extender could remedy the problem.


    If you’re looking to connect a device such as a game console or IP-phone to your WiFi extender, ensure that extender has built-in Ethernet ports.

    Who benefits from a WiFi extender?

    Extenders helpful in homes where walls or interference from other devices lead to dead spots for WiFi reception. Devices offering easy setup can range from $29 to $120, with the sweet spot hovering in the $80 range.

    An adjacent category to Wi-Fi extenders is AC WiFi range extenders. AC-based range extenders provide a similar resolution to the problem of spotty WiFi, but their setup is more complex and can be a bit more costly. See our “Tips for Choosing a WiFi Extender” section for more information.

    Before you start

    Prior to choosing a WiFi range extender, it’s important to establish proper “benchmarks” for your home WiFi throughput. Basically, this means identifying the areas in your home where WiFi signals are weakest.

    We recommend this series of steps:

    Step one

    Download an app to your mobile device for portable testing. Ookla and Speed Test are two of the more popular WiFi speed testers, and both are available for IOS and Android for a minimal cost (or free).

    Step two

    Run a throughput test in the general area of your wireless router and note the results.

    Step three

    Visit the spot (or spots) in your home where WiFi reception is slower. There is no hard and fast rule, but if your tests in areas away from your router are less than half of your base signal, it’s time to consider a range extender.

    Step four

    Purchase and install your WiFi extender. (See “How to Set Up Your Extender” for more details.) Buyer note: not all range extenders are built equally. Many promise the ability to extend a signal up to 10,000 square feet, while others have the ability to take signals from multiple bands of the router and combine them to create a more powerful repeated signal.

    Step five

    Retest your throughput speed in the area that previously experienced less-than-optimal WiFi. If you don’t see a significant boost, it’s possible you may need a different range extender.

    Adjust the antennas on your WiFi extender to get the best connection. It may take a few configurations to find the best one.

    Tips for choosing a WiFi extender

    • It is best to select the same brand for your WiFi extender as your router. This generally ensures that the products have the same chipset and software.
    • You may be attracted to an extender that offers simple setup. That’s fine, but bear in mind that more advanced models that provide throughput on multiple bands require a more complex setup, with separate bands needing individual setups.
    • For maximum throughput, select a model that supports both the 2.4 and 5 GHz bands. Older models with only 2.4 GHz offer little more than 50% of the router’s signals, while extenders that also support the newer 5 GHz band provide stronger signals to weaker zones. The reason for this has to do with the need for the extender to simultaneously communicate with the base router and the client device. With one band, the network must perform both functions, but with two separate bands, one can talk to the router while the other services the targeted deficient zone.

    When to consider a powerline WiFi extender

    In some cases, a standard WiFi range extender will not bring new bandwidth life to spotty areas of reception. If a building’s architecture prohibits central location of the extender, for example, you could run into this problem.

    In such scenarios, an AC- or powerline-based WiFi extender should be considered. Generally, AC-based extenders cost slightly more than their non-AC counterparts. As more companies enter the market, however, prices continue to drop.

    Powerline solutions come in pairs, with a base unit that plugs into an outlet near the router and a second unit that sits in an area with poor bandwidth throughput. The unit close to the router plugs directly into the router via Ethernet cable; the signal travels through the home’s electrical circuitry to the extender.

    By and large, this method can provide the best throughput to weak or dead bandwidth zones. However, the AC-based solution has its drawbacks:

    • The powerline approach is only as good as the home’s electricity circuitry. In older homes where the wiring has not been updated, an AC extender is likely the wrong choice for extending WiFi signals.
    • If you live in a home where a number of surge protectors are in place, these pieces of hardware often weaken any signal in its path.

    Not all WiFi extenders work with every computer, so be sure to check the compatibility before purchasing one.

    How to set up your extender

    • First, unbox your extender. If your device has remote antennas, raise them to a fully vertical position. Plug it into an electrical outlet in the same room as your home wireless router.
    • Find the WPS (WiFi Protected Setup) button on your router. If your router does not have a WPS button, the manufacturer will provide additional instructions which include how to connect an Ethernet cable from your router to your WiFi extender.
    • Press the WPS button on your range extender. Then, press the EPS button on your router. The WPS button on your range extender will turn a solid green when a connection between the devices is established.
    • If your router supports the 5 GHz band, repeat the WPS process for both devices.
    • Unplug your WiFi range extender and select a location about halfway between your weak signal area and router. The extender must be in the range of your router to ensure a strong signal.
    • Plug your extender into an outlet and wait for the LED light to turn green. (For most range extenders, there will be a signal light that indicates the extender is within range of the router. Ensure your indicator light says your extender is within the proper range of the router.)
    • Connect your client device (a laptop, for example) to the extender. You should find a network name which is the same as your established SSID (Service Set Identifier) but with a suffix _EXT. The password, or “key,” will be the same as your existing network password.
    • At this point, test the throughput from the extender with a mobile device app to ensure it provides adequate throughput. If the range extender does not offer the desired results, it is possible you may need to look at other solutions, such as an AC or powerline WiFi range extender.


    How much should you expect to pay for a good WiFi extender? As mentioned above, you could spend anywhere from $30 to $120 for a good one. Many great ones cost around $80.

    The cost will vary based on the answers to these questions:

    • Does the extender offers single or dual band operation?
    • Does the extender have external antennas that can be moved for optimal reception?
    • Does the product offer easy, step-by-step setup?
    • Does the vendor offer free, 24-hour technical support?
