You can’t have a fast network all over your home without a decent router. The Wavlink Whole Home Mesh WiFi System is a dual band AC1200 networking device that provides coverage up to 4000 sq.ft. It uses beamforming technology to improve your signal. Two Gigabit Ethernet ports are also available.
You can set the device up with a QR code or Wavlink. You can use the companion iOS/Android app to share passwords and prioritize devices.
