<p>The top-rated models can cure Wi-Fi dead spots, but sometimes it makes more sense to invest in a mesh router. Here's what you need to know.</p>

<p>To anyone with a slow, spotty internet connection, Wi-Fi range extenders sound like a bargain. You buy one for as little as $20, plug it into an outlet, and your problem is solved. Or so the marketing goes. The truth, however, is more nuanced.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>As testing by Consumer Reports shows, Wi-Fi range extenders can be useful in certain situations, but don’t think of them as a slam-dunk fix for all of your Wi-Fi woes.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>In some cases, a mesh router system may be a better solution. Those have a hub and one or two satellite units that then work together to spread Wi-Fi evenly throughout your home.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>The problem is that a good mesh router setup starts at around $150. You’ll pay even more if you want cutting-edge features, like support for Wi-Fi 6E—let alone Wi-Fi 7.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>We began testing Wi-Fi extenders at the height of the pandemic in 2020 to help consumers optimize their home networks for remote work. The devices have since become so popular that we now test them year-round.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>One model in our ratings still costs roughly $20. Others have stretched beyond $100 and even $200. That’s a mighty big sweep, spotlighting the need for a reliable performance evaluation.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>So what have we learned in our testing?</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>While Wi-Fi extenders can increase the range of your wireless network, their effectiveness is limited by a host of factors, including the speed of the internet connection coming into your home, the distance from your router, the areas in your home in need of Wi-Fi coverage, and the Wi-Fi demands of your family.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Here’s a closer look at our findings.</p>
<!-- /wp:paragraph -->

<!-- wp:heading -->
<h2 class="wp-block-heading">How Does a Wi-Fi Extender Work?</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>While it’s tempting to think of a Wi-Fi extender as something that can beam fast, reliable Wi-Fi throughout your home, it’s really more of a spot-fix for a single, specific dead zone in your layout.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>To get the best results, you have to plug the extender into a power outlet midway between your router and the troublesome area. The extender then picks up the Wi-Fi signal from your router and pushes it deeper into your home.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>But you’re likely to notice a significant drop in throughput speeds in the “extended” network. That’s in part because an extender relies on the same frequency band as the router itself.&nbsp;</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>“In the radio frequency world, they’re called repeaters, but in Wi-Fi they’re called extenders,” says Henry Parra, who leads CR’s testing of smartphones and wireless routers. “They repeat the signal on the same frequency to extend coverage.”</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>Because the signal is now going through an intermediate step, throughput—or what you and I might simply call “speed”—is now cut in half.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>For example, let’s say you’re standing right next to your Wi-Fi router (where the signal is strongest) and get 50 megabits per second, which is fast enough to stream one, <em>maybe</em> two 4K Netflix shows at the same time. If you were to set up a Wi-Fi extender, then you’d be looking at about 25 megabits per second with the extended network. And that’s in an ideal world, where the Wi-Fi signal hasn’t been degraded by obstacles such as thick walls or large appliances.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>By contrast, mesh routers use two different frequency bands, which limits the speed loss to roughly 10 percent. They also allow you to move the satellite units around your home, steering a Wi-Fi signal around obstacles.</p>
<!-- /wp:paragraph -->

<!-- wp:heading -->
<h2 class="wp-block-heading">What CR's Testing Shows</h2>
<!-- /wp:heading -->

<!-- wp:paragraph -->
<p>There are currently 13 Wi-Fi extenders in our ratings, all of which you simply plug into an outlet and set up using either a mobile app or a web-based wizard.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>We use a professional wireless performance software suite to test each model’s capabilities. This software measures the throughput of the extender directly from a nearby computer. That gives us more precise data than if we were to rely on a web-based service such as&nbsp;Speedtest.net&nbsp;or&nbsp;Fast.com. That’s because data is transmitted directly between the extender and a computer and not over the internet, which can introduce latency. We do three “runs” and then average the measurements to come up with our final throughput score.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>In our labs, we place the extender being tested inside a room down the hall and around the corner from the laptop used in the test. This is done to simulate a typical home environment, where you might have your router in one room and the extender in another. We then vary the distance between the laptop and the extender (from 8 to 20 to 35 to 55 feet) to measure the extender’s effectiveness at various distances.&nbsp;</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>In practice, there’s a balance you want to strike when setting up an extender. The farther you place it from the router, the more you risk losing signal speed. But place it too close to the router and you may not be able to push the signal to the desired location. In the instructions included with the extenders, manufacturers recommend placing the unit about halfway between the router and the area you hope to reach.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>So to answer the question of whether or not you should get a Wi-Fi extender, here’s how to think about it. </p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>If your goal is simply to get Wi-Fi in that one dead zone in your home, a spot where you like to browse the web and check email, our testing shows that you should be prepared to spend around $50 for an extender. You can pay more for bells and whistles like built-in Ethernet and USB ports, but the performance is roughly the same.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>At the moment, extenders that cost less than $30 fare less well in our tests.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>For example, the TP-Link RE220, which retails for about $20 (and which we’ve seen on sale for as low as $17 on Amazon), and the Netgear EX6120, $36, sure do seem appealing. But our tests show their performance to be quite poor, earning low marks in terms of speed (even at short distances) and versatility. So you have to either limit your expectations or shop at a retailer with a generous return policy.</p>
<!-- /wp:paragraph -->

<!-- wp:paragraph -->
<p>If you’re hoping to do more demanding tasks, like stream 4K video or play online games that require low latency, you ought to consider a mesh network. Those range in price from $100 to $1,000 but offer a more robust solution, using two or three units that work together to deliver fast Wi-Fi throughout your whole home—not just to one room. And, really, given that prices for mesh routers have fallen quite a bit since the technology was first introduced, you can now find capable models for well under $150 from well-known brands like Google and TP-Link.</p>
