If your Wi-Fi 6 router is having trouble delivering strong wireless signals to the far corners of your home, and you don't want to spend hundreds of dollars on a Wi-Fi mesh system, a range extender could be just what you need. I'm the editor responsible for Wi-Fi networking reviews here at PCMag. I know that range extenders can be finicky, but I also know what makes a good one. And I'm here to tell you that this Prime Day deal on the TP-Link RE600X AX1800 Wi-Fi 6 Range Extender is one of the best deals I've seen. Sometimes, a pretty good product gets made great by a big discount. This is one of those times.

Easy to install, this large dual-band extender simply plugs into a wall outlet and connects to your existing router. Normally priced at $99.99, it offers a fairly inexpensive way to boost Wi-Fi coverage without having to invest in a new router or mesh system. But right now, for Prime Day, it's a snap-it-up steal at just $39.99.

(Don’t miss out on any of the savings. Make sure to keep an eye on our roundup of the Best Prime Day 2025 Deals.)

In our review of the RE600X, we noted that this range extender has good throughput performance and fast, easy setup. In our signal strength test, the RE600X did a good job of providing strong 2.4GHz and 5GHz Wi-Fi signals to the den, living room, and garage (the target areas in our test house).

As for the nitty-gritty specs? The RE600X is a dual-band AX1800 extender capable of reaching theoretical data rates of up to 574Mbps on the 2.4GHz band and up to 1,201Mbps on the 5GHz band. It employs Wi-Fi 6 technologies such as WPA3 encryption, MU-MIMO data streaming, Orthogonal Frequency Division Multiple Access (OFDMA), and beamforming.

It can operate as an extender or as an access point (via a wired connection to your router), and it can be pressed into service as a mesh node when connected to a TP-Link OneMesh router. That makes it an especially good choice if you already own a compatible router.

Overall, the RE600X does a good job of extending 2.4GHz and 5GHz wireless signals in your home, but it doesn’t support all Wi-Fi 6 features. That led us to give it a "Good" 3.5-star rating when we initially reviewed it. But now that it's available for less than half its list price, it's a much better value.
