If your Wi-Fi signal is struggling to reach every corner of your home, a signal booster — also known as a Wi-Fi extender — might be the fix you need. Whether you're dealing with annoying dead zones, buffering video calls or laggy gaming sessions, the right Wi-Fi extender can help expand coverage and improve connectivity without forcing you to move your router.
There are different types of Wi-Fi extenders to choose from. Some models use external antennas to push the signal farther, while others, like mesh extenders, create a seamless, whole-home network. If you're simply looking to extend coverage into a specific room, a Wi-Fi repeater can do the job — but it may cut your bandwidth in half. More advanced extenders, however, can help maintain strong speeds and reliability throughout your home.
We've rounded up the best Wi-Fi extenders to suit different needs, whether you're looking for an affordable fix or a high-performance upgrade.

Best Wi-Fi extender for 2025
TP-Link Best Wi-Fi extender overall TP-Link AX3000 Dual-Band Wi-Fi 6 Range Extender (RE705X) Maximum transfer rate: 2402 Mbps | Range: 110 feet | Number of antennas: 2 | Number of USB ports: 0 | Wi-Fi 6: Yes | Number of bands: 2 | Wi-Fi speed: 5GHz (2402 Mbps), 2.4GHz (574 Mbps) TP-Link has a bunch of Wi-Fi extenders under its umbrella, but the one that will likely serve most people the best is this AX3000 model, which comes in two variations: the RE700X and the RE705X. Both extenders have the same specs, including Wi-Fi 6 support, but the 705X has a slightly different design with pull-out antennas on either side. I tested the 705X, so I’m basing my recommendation off of my experience with that model, specifically. Setting up this extender was as easy as plugging it in and following instructions in TP-Link’s Tether mobile app. All of the devices I tried followed the same basic setup process: first, plug in the extender close to your wireless router, follow instructions in a mobile app or on a setup webpage, and once the connection is established, move the extender to your desired location. It took all of five minutes to pair the 705X with my Verizon FiOS router – probably the most time-consuming bit was deciding what I wanted to name the new 5Ghz and 2.4Ghz networks. I went with the same name for both because I didn’t want to manually choose from two different bands when connecting things like my phone or laptop. The device will automatically pair your device with the appropriate band — for example, connecting most smart home gadgets to the 2.4Ghz network, which often helps reduce latency. The permanent location where I moved all of the extenders I tested was in my basement, since that’s where we can get the spottiest Wi-Fi signal. I first ran speed tests on my iPhone and MacBook using Speedtest.net and Speedcheck.org so I could compare them with the standard speeds I got when connected to my router’s main network. Unsurprisingly, the speeds generated by TP-Link’s extender were much slower than those from my router’s network, but that was the case with all of the devices I tested. Only our top pick (see below) got close to my router’s standard speeds, but I expected this. Wi-Fi extenders aren’t going to make your connection better – they’re just going to give you a wider area of coverage. From a spec perspective, both the 705X and the 700X are rated for speeds up to 2402 Mbps on the 5GHz band and 574 Mbps on 2.4GHz band. Despite the results of my tests, I was happy to discover that I wasn’t held back by the 705X’s seemingly slower speeds. I worked as normal for hours with my phone and laptop connected to the extenders wireless network, answering emails, messaging in Slack, streaming YouTube videos and otherwise maintaining a few dozen tabs in Chrome, without any hiccups or noticeable slow-downs. I was not surprised to find TP-Link’s Tether companion app to be easy to use, if a little simple, because that was my experience with TP-Link’s smart home app. Tether is specifically used with the company’s networking devices, and you probably won’t spend a ton of time in it after initial setup. I especially like that you can name wireless devices that are connected to your extenders network like your phone and smart TV. That makes it much easier to know which things in your home are constantly paired with the extender rather than your router’s default network. One important thing to note with these TP-Link extenders is that they both support OneMesh, which is the company’s feature that allows you to create one seamless network if you have a compatible mesh router. Since I’m still using the router provided to me by my ISP, I wasn’t able to test out this feature, but it works like this: if you have a OneMesh router and OneMesh-compatible extenders, you can link them all together under the same network name. So rather than having a router network and an extender network under the same roof, everything would be linked and filed under your main network’s name. It’s a small perk that becomes not so small if you have a spotty extender, or even just an awkwardly laid-out home. In my testing, I found my phone disconnecting from some extenders’ networks when I went upstairs to the main floor of the house from my basement. It would then attempt to reconnect to the extender network, when really I would have preferred it to default back to my router’s network. That thankfully didn’t happen with TP-Link’s RE705X, but it’s something to keep in mind when considering buying a Wi-Fi extender at all. If you can get one that has a feature like OneMesh, it’ll make your life much easier. Coming in at $130 and $120, respectively, the RE705X and RE700X may not be the cheapest Wi-Fi extenders out there, but their coverage range, latest Wi-Fi support and max speeds make either of them a good pick. If you know exactly where you want to put an extender and it’s not in an awkward or hard-to-reach location, the slightly cheaper, antenna-free RE700X may work just fine for you. But if you want that extra ability to tweak antennas to suit your needs, the RE705X is the way to go. Pros Easy setup process
