Required Network Settings to use Play-Fi on your PC
Play-Fi will only work on Wi-Fi networks that are set up as a "Home network" or a "Work network" on your PC, since these provide higher security settings than “Public” Wi-Fi networks. If your PC is connected to a "Public" Wi-Fi network, Play-Fi products will not be detected.
To check your network's settings go to the desktop, right click the network symbol in the taskbar (usually the lower right corner of the screen), and then click 'Open Network and Sharing Center'.
If the current network is set to "Public" (#1 in the image below) then select the link "Public Network (#2 below) and change the setting to "Home" or "Work".
