The simple answer is yes, you can use Genie on Wifi, however it may impact on the stability of your connection from Client to the Server.
Genie is a network intensive application that requires a stable and fast network connection between the Genie Server and Genie Client machines. Wireless (Wi-Fi) networks by their very nature are prone to fluctuation in connection due to the signal strength and traffic on the network. An Ethernet connection means that the computer is physically connected by an Ethernet cable to the network and as such eliminates the common network connection issues that can be found when utilising Wi-Fi. Due to this it is our recommendation that you access Genie via a wired Ethernet connection.
