As Wi-Fi congestion has become more of an issue, routers have become more sophisticated. As a result, the cost of routers has gone up significantly, and it's not uncommon to pay $300 or more. Many modern routers use a mesh technology that include multiple devices placed throughout the house. But if you have a small space and need something simple, the Archer A7 from TP-Link is a good choice.
The Archer A7 is a dual band gigabit wireless router that can cover up to 2,500 sq. ft. It's compatible with all Wi-Fi devices 802.11ac and older. It includes 4 gigabit LAN ports for hardwired devices and it has a USB port for sharing media over the network.
The Archer A7 router has software for parental controls and guest access. It has an intuitive Tether app so you can easily set up your router and manage your Wi-Fi at home, or check in remotely over the internet. It even has Alexa and IFTTT integration so you can use your voice to turn the guest Wi-Fi on or off, and trigger actions with IFTTT.
