TP-Link RE715X at First Glance: Pricy With Promising Features

The RE715X isn’t the first TP-Link product I’ve had the pleasure of testing, but it’s the first TP-Link range extender I’ve used. I’ve found myself impressed with TP-Link’s products, particularly its mesh network systems, and the RE715X shows major promise with impressive features like Wi-Fi 6 compatibility and gigabit speeds.

Compared to other Wi-Fi range extenders, the RE715X is on the higher end of the price spectrum but does come with quality features that justify the cost. Imagine the power of dual-band Wi-Fi 6, where your devices can enjoy their own dedicated lanes — 5 GHz for blazing-fast speeds up to 2,402 Mbps and 2.4 GHz for more stable connections, all thanks to cutting-edge tech.

If you’re like me and can’t stand buffering or dropped connections, the uninterrupted streaming feature is a lifesaver. With TP-Link’s OneMesh technology, your whole house becomes a seamless Wi-Fi wonderland, where you’re always connected no matter where you roam. However, you do need a router that supports this feature. My Spectrum-provided router, sadly, doesn’t support this technology.

The gigabit Ethernet is perfect for hooking up your smart TV, gaming console, or PC, ensuring everything stays fast and lag-free. The cherry on top? The TP-Link Tether app, which I have experience using, makes setup and management a breeze. It’s like being the Wi-Fi wizard of your own home.

TP-Link RE715X Installation: Simple and Straightforward

Rarely is technology as plug-and-go as installing the RE715X, but I’m happy to report that installation couldn’t have been easier. Simply plug in the extender and download the intuitive app to get you up and running in less than 10 minutes.

Unboxing and Initial Setup

The TP-Link RE715X came with a handy guide that walked me through the steps to install the range extender. A companion mobile app was also necessary for setup. TP-Link has multiple apps depending on the device you’re setting up. For this range extender, I used the Tether app. Don’t feel bad if you downloaded the wrong one at first, because I made the same mistake when attempting to set up the TP-Link Deco S4.

I’ve tested a handful of mesh network systems, and installing this range extender proved even easier. All I had to do was plug the device in close to our existing router (this won’t be its permanent location) and wait for the flashing blue light at the top to turn solid as it located our existing Wi-Fi. This waiting period was the longest part of the whole process and took about three to four minutes.

Once that light was solid blue, I opened up the Tether app to complete the download. I clicked through to select the download options for a range extender and then followed the prompts. Once our extender was located, we set up a password to manage our device and then linked it to our existing home Wi-Fi.

After applying our settings, we were free to move our extender to a new location. Ideally, you’ll choose a spot near known dead zones. When we plugged it into that location, we waited for the lights to all turn solid blue. And, just like that, we were up and running! The whole process took less than 10 minutes from start to finish.

Navigating the Mobile App

The Tether app was intuitive and straightforward, making setup and navigation a breeze. I could easily update any settings inside the app, including updating passwords and controlling LAN or DHCP settings. Overall, the app provided the basic necessities I needed. But since I’m only using it to extend Wi-Fi rather than create a mesh network, the basics suited us just fine.

One option we had with the RE715X is OneMesh. This feature enabled us to establish a mesh network, expanding our current network’s reach and delivering high-speed Wi-Fi throughout our home by leveraging existing compatible devices. This feature eliminated the need for investing in a new mesh system. However, we had to make sure our current router was compatible. If it’s not already, and you have to purchase a new router, it might not be the most cost-effective option compared to simply investing in a mesh network system.

To get the most out of our device, the app helped us find the best location for our extender. We checked the signal strength of our current location to see if we were getting maximum coverage. And, if the app found our extender was too close to our router, it suggested moving it to improve reach.

While many features are included with the device, you can choose to enhance security and advanced parental control features. Both of these add-ons come with a free 30-day trial. If you’re considering upgrading, you can spend a month with these features to determine if investing in them makes sense for your needs.

TP-Link RE715X Performance: Solid Speed Improvement

I live in a two-story, 2,500-square-foot home, and while my main router is set up in a central location, the internet connection on the second level can be challenging. The room on the second floor toward the back of the house tends to record the lowest speeds. I ran a test with the extender to see how Wi-Fi speed improved.

Testing the Router

Before setting up the range extender, I ran three Speedtest by Ookla tests on my Spectrum-provided router on the second floor of my house and logged 299 Mbps. After installing the RE715X, I tested the speeds three times again and logged 340 Mbps, an increase of 14 percent in download speeds.

Upload speeds also saw an improvement, which often hasn’t been the case when I’ve tested mesh network systems. Upload speeds generally remain consistent. On my Spectrum router, upload speeds were 16.5 Mbps, and with the extender logged 22.1 Mbps, showing a 34 percent increase.

The increase may not seem high, but I put the extender to the test while working. I enjoyed a noticeable improvement when navigating online using the extender compared with my regular router. Navigating social media apps also showed an improvement compared to previous usage.

While I used a Spectrum router for this test, the normal router I use in my home is the eero Pro 6 mesh network system. In this location, I generally get speeds between 350 Mbps and 400 Mbps on the second floor. These speeds are less than I achieved with the RE715X, but not by much. And when taking price into account, the range extender suitably improves Wi-Fi speeds.

A great benefit to using this extender is that it can be easily moved without requiring a new setup. If you use it in your office and then have guests coming and want to move it to the guest room, it’s a simple fix. One downside is the extender’s size: the unit blocks the entire outlet, so you wouldn’t be able to plug in another device or cable with it.

Comparing to Competitors

As range extenders go, the RE715X is one of the top products on the market. Its versatility, effectiveness, and ability to create a one-mesh network stand out against similar products. The extender rivals one by Asus, the Asus RP-AX58. While both have similar features, the Asus model is slightly less expensive than the RE715X but features less coverage. The RE715X features 600 square feet, more coverage than the RP-AX58. But the RP-AX58 is able to maintain solid upload speeds no matter the distance from the main router.

Aside from the RE715X, TP-Link has a suite of other range extenders. The TP-Link RE315 is a budget-friendly model but only has 1,500 square feet of coverage, which could be a good option for smaller homes but falls short for the average two-story house. As far as performance among these three extenders goes, the RE715X outpaces the other two and doesn’t show a significant drop in speeds over farther distances.

Here’s a side-by-side comparison of the RE715X compared to other top Wi-Fi extenders on the market.

Our Verdict: A Must-Have for Two-Story Homes

Despite its higher price point for range extenders, the RE715X is well worth the cost. For two-story homes with Wi-Fi dead zones, this extender fits the bill to deliver high speeds and offers versatility to provide speed wherever you need it. This Wi-Fi extender is perfect for homes with many family members and high-bandwidth needs, whether for working from home, or streaming 4K content, or online games. The RE715X ensures everyone in the home can access Wi-Fi speed without worrying about irritating slowdowns or dead zones.

How We Assess Routers

To keep our evaluations consistent, every extender we review goes through the same real-world testing process. The TP-Link RE715X was used in a lived-in home environment for a full 30 days to measure how effectively it improves coverage and maintains connection stability. During that time, our broadband team focused on signal strength, reliability across distance, and how well it handled multiple connected devices. Testing was performed with the Speetest by Ookla app and included busy evening usage, bandwidth-intensive tasks like streaming and video calls, and speed checks in areas that previously had weak Wi-Fi. For my household, this was on the second floor of my home, specifically the room furthest from the stairway. I performed three rounds of tests in each location to get the most consistent results.

We score each category using a weighted 1–5-star system, with performance and overall value carrying the greatest influence. Below, you’ll find our ratings across five key categories, along with a closer look at how the RE715X performed throughout testing in my two-story home.
