At its regular price, the 3-pack sells for around $130 and can jump as high as $150. Today's deal at Amazon has been matched at B&H but is still $10 better than Best Buy.

$110 at Amazon

This mesh system really is our pick for the best mesh Wi-Fi router under $200. We like it not only for the price, which is amazing with today's deal, but also because it can cover a huge amount of space and delivers speeds up to 800Mbps. TP-Link also makes setting it up really easy to do thanks to the Deco app, which works on Android or iOS.

One of the smart features of the Deco S4 is that it can work with your Amazon Alexa voice assistant. You can turn Guest Wi-Fi on or off with a simple voice command, giving your guests access to your Wi-Fi without giving up your password.

The three units work together to provide up to 5,500 square feet of Wi-Fi coverage. That means as long as you strategically place them around your home, you should be able to get Wi-Fi in every corner of where you live. Plus, the routers work seamlessly so you don't need multiple logins or passwords. As you move from out of one router's range and into another the Wi-Fi doesn't change and doesn't interrupt whatever you're doing.

Connect up to 100 devices on this network, too. You might not have quite that many, but you'd probably be surprised just how many you do have if you stop to count. Keep your TV, gaming consoles, smartphones, laptops, tablets, video doorbells, home security cameras, and more all connected to your Wi-Fi without so much as a hiccup. There are even parental controls so you can limit children's devices.
