We've tested and used more than a dozen of the best Wi-Fi extenders to help you fix your Wi-Fi dead spots and boost signal strength to every corner of your home. These small and inexpensive Wi-Fi signal boosters provide a quick solution for weak wireless signal and spotty coverage.
We rigorously test every Wi-Fi extender we review to get a clear picture of how well each device performs. This testing is performed in our testing facility and our reviewer's suburban home, in addition to hands-on use. Overall, our rating criteria include design, range, throughput, setup, and which settings you can adjust. In the final analysis, though, it all comes down to value — which extender provides the most for the lowest cost.
We use Ixia's IxChariot testing software to measure throughput at a variety of distances and environmental conditions. This includes testing with the extender placed at 50 feet and 75 feet from the router. The software simulates traffic in a busy wireless network while measuring data flow back and forth. The results are shown in megabits per second (Mbps) at a distance from the extender, with higher numbers indicating better performance.
Measuring the throughput at various distances also lets use determine the effective range of the extender, giving you a better understanding of how well a device will do in covering the farthest corners of your home.
Based on our rigorous evaluations, which include in-depth lab tests and hands-on usage in a real home, the best extender on the market is the Netgear Nighthawk X6S EX8000. It offers fast speeds, excellent reach and an array of features that make it easy to use. Our top value pick is the Coredy E300 Mini WiFi Range Extender, which gives you a Wi-Fi boost for under $50.

1. Netgear Nighthawk X6S EX8000 Tri-band WiFi Extender
The best Wi-Fi extender overall
Antennas/Removable: 6 internal/No | Wi-Fi Spec: AC3000 802.11ac tri-band | Ports: 4 gigabit Ethernet, USB 2.0 | Size: 8.9 x 6.7 x 3.7 inches
The Netgear Nighthawk X6S EX8000 Tri-band Extender emerged as the best Wi-Fi extender we've tested by a large margin, with faster data speeds and an enormous range.
The Nighthawk X6S uses a desktop design that's much larger than the average plug-in signal booster, but that size allows for more antennas (six in total) and beefier hardware that offers tri-band coverage out to 168 feet. You can even use multiple X6S extenders to create a mesh network for larger homes. It's big and expensive, but it's worth every penny.

3. TP-Link RE650 AC2600 Wi-Fi Range Extender
Best for Large Homes
Antennas/Removable: 4 external/No | Wi-Fi Spec: AC2600 802.11ac dual-band | Ports: 1 gigabit Ethernet | Size: 6.3 x 3.0 x 1.8 inches
The TP-Link RE650 takes a top position as the best plug-in range extender we’ve tested, and our pick as the best repeater for big homes. It packs a lot of power, and delivers great speeds at up to 75 feet.
That performance came second only to our top overall pick, but the TP-Link RE650 offers competitive speeds in a handy plug-in design. With four external antennas and dual-band wireless-AC support, the TP-Link RE650 is a great choice for large homes. You can also set up and monitor your extended network with TP-Link's handy Tether app, which puts advanced settings and security tools right on your phone or tablet.

4. Netgear EX6200 Dual Band AC1200 WiFi Range Extender
Best Wi-Fi extender value for large homes
Antennas/Removable: 2 external/Yes | Wi-Fi Spec: 802.11ac dual band | Ports: 5 Gigabit Ethernet, USB 3.0 | Size: 9.7 x 6.9 x 1.2 inches
The Netgear EX6200 gets a nod as the budget-firendly alternative for large homes, offering a less expensive alternative to the TP-Link RE650 that gets our top recommendation. It lacks a few features, most significantly a dedicated backhaul channel for data, but it balances that omission with a great price. On top of that, you'll get excellent performance, great range, and a flexible setup that can position the extender horizontally or vertically.

Antennas/Removable: 4 external/No | Wi-Fi Spec: 802.11ac dual band | Ports: 1 Gigabit Ethernet | Size: 4.9 x 3.2 x 1.7 inches
Need to beef up your Wi-Fi network but don't want an extender that stands out? The Linksys RE7000 Max-Stream AC1900+ Wi-Fi range extender is compact and low-profile, with a design that won't block other outlets or stand out as a garish tech product. But aside from the subtle design, the Linksys RE7000 Max-Stream AC1900+ offers solid performance and set-up assistance that helps you find the right spot for optimal performance.
6. D-Link DAP-1720 Wi-Fi AC1750 Range Extender
Best for Two-Story Homes
Antennas/Removable: 3 external/No | Wi-Fi Spec: 802.11ac dual band | Ports: 1 Gigabit Ethernet | Size: 6.4 x 3.3 x 1.5 inches
D-Link's DAP-1720 is easy to set up, provides a mobile app and can help fill a home with Wi-Fi, but it serves up patchy performance and is so large that it risks blocking adjacent AC outlets. Despite some irregular performance, the D-Link DAP-1720 does particularly well when pushing signal to a floor above or below, making it a smart choice for multistory homes.

Do I need an extender, booster or a repeater?
Confused about the difference between Wi-Fi extenders, signal boosters, and wireless repeaters? While each term gets used frequently, this is one bit of tech jargon that shouldn't be confusing, because they all mean the same thing.
A Wi-Fi extender works by rebroadcasting your Wi-Fi signal, both strengthening poor signal and expanding the area it covers. So, calling a Wi-Fi extender by another term, such as a wireless repeater or range extender, is entirely correct. As long as your Wi-Fi signal booster is set up properly, it won't matter what you call it.
The one time it may not be quite so simple is with a mesh router system. Mesh routers also extend the Wi-Fi coverage in your home, but instead of just repeating your wireless signal to give Wi-Fi a boost, they use a more complex system of individual devices producing signal, multiple data channels and automatic configuration, providing more seamless coverage and better overall performance.
Quick tips for shoppers
- How Much Should a Wi-Fi Extender Cost? The cheapest Wi-Fi repeaters will often sell for less than $50, and our current budget pick sells for half that. Newer signal boosting devices have support for the latest wireless standards and offering technologies like beam-forming and Mu-MIMO for enhanced performance will often cost more, but even the best extenders can be had for less than $200.
- Plug-In or Desktop? While most Wi-Fi extenders use small plug-in designs that connect directly to a wall outlet, they aren't the only option. Some use larger designs that sit on a desk or shelf, more like a traditional router. These larger devices don't have the same size and weight limitations of plug-in units, allowing for better antenna placement and better internal hardware. Plug-in models, on the other hand, will often be less expensive and more convenient to install.
- Match Wi-Fi Standards: While you may not pay much attention to which wireless standard your router uses, it will definitely have an impact on how helpful your extender is. If your wireless router uses the current 802.11ac standard, you’ll want to be sure your extender does, too. The older 802.11n standard is slower and often is limited to one band, which will create a bottleneck in your Wi-Fi coverage, slowing down all of your browsing and streaming. But that's a problem only if your router is offering better speeds. If you have an older wireless-N router, then a matching extender will do the job just fine.
- Placement Is Everything: Both wireless routers and Wi-Fi extenders use radio waves to share data back and forth with your internet connection. You need to find somewhere that's close enough to the router to grab a strong signal to rebroadcast, but far enough away to extend the network's range to where it's needed. Need more help? Check out our guide to Wi-Fi extender placement.
- Consider an Upgrade: If your wireless router isn't providing the speeds or coverage you want, it may be better to skip the Wi-Fi extender entirely and get a new router. Newer models offer better performance, and mesh routers will let you expand your wireless coverage across even the largest home.
