Cover your home in Wi-Fi with TP-Link's Deco S4 mesh network down to $110

Time to eliminate all the dead zones and weak Wi-Fi around your house. Upgrade to one of the best budget mesh networking systems around, and get the TP-Link Deco S4 mesh WI-Fi system 3-pack on sale for $109.99. At its regular price, the 3-pack sells for around $130. You can find it going for that price at some retailers like Best Buy, but it also regularly jumps as high as $150, which is what it's going for at other places like B&H. Either way, no one has it as low as Amazon right now, and Amazon has never featured it this low either.

TP-Link Deco S4 Mesh Wi-Fi System | $20 off

This is Ecobee's newest smart thermostat, and it's just called SmartThermostat. The name is annoying, but the product is fantastic. It improves on all the previous generations and includes a whole new design with a glass finish, a vivid touch display, a quad-core processor, dual-band Wi-Fi, Bluetooth, and far-field voice recognition that can pick up your commands from across the room. Like the Ecobee 4, this one comes with its own smart sensor. And you can add more.

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 interupt 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.
