Looking to get great WiFi with a fairly easy setup? UniFi is the way to go. This 5 or 6 minute video shows you unboxing to complete network.
With a UniFi, or Ubiquiti, you create a main account. Then, per network, you install or purchase controllers. You can download software to a computer or purchase a Cloud key which is basically a piece of hardware that is a controller. The controller helps you set up your UniFi access points and wireless networks. Finally you have your access points that you mount and set up. We used the UniFi AP-AC-PRO access point.
With an access point like this you can create multiple networks per device and create rules for each one. You can also mesh them together.
