TP-Link AX5400 WiFi 6 Range Extender with Ethernet Port - High Speed Tri-Band Wireless Signal Booster for Home & Office | Internet Repeater Amplifier with Access Point Mode | Easy APP Setup & OneMesh Compatible (RE815X) | Perfect for Gaming, Streaming & Large Homes

I wanted to increase the WiFi coverage in my house, and this extender does a really good job of that! My router is a TP-Link AX5400 (Archer AX73), and is "EasyMesh" compatible. I tried using other less expensive (aka "cheaper") WiFi extenders, and I got what I paid for. TP-Link recommends this particular extender (the RE815X), and it works great. Setup was a very easy - Plug in the extender while it's near the router, press the WPS buttons on both devices. They link up, and you're good to go. Move the extender to where you want it, check that the signal light indicates it's receiving an acceptable signal, and that's it. The router and extender together use a third 5GHz radio to communicate with each other, and the extender essentially extends both the 2.4GHz and the 5GHz band so that BOTH bands get an extended signal. The end result is like having two routers. As for the size of the extender, it's larger than a dual outlet wall plate. I put mine in an unused outlet (imagine that!) under the counter in the kitchen. I put my router in one corner of the house floorplan, and I put the extender in the opposite diagonal corner. I now have better coverage for all my smart home and IOT devices. Devices on the second floor now get a 5GHz connection where they only had coverage for a 2.4GHz before. The signal is strong enough to reach Alexa devices in the backyard. The signal strength for my Ring cameras has improved with the addition of this extender. If I could change just one thing about it, it would be that the connected device names show up in the management interface of the extender. The router will identify all the devices connected to the network and show the name, MAC address, and DHCP assigned IP. The extender shows the devices that are connecting to the network using the extender, but the it (the extender) only shows the MAC address and IP of the devices, and not the name. This would be a "nice-to-have", but isn't a "show-stopper" for me. Overall, I'm very pleased with this product and I would recommend it. It might be seen as a little "pricey", but I think the overall value is well worth the cost. I have no regrets buying it.
