Dear customer, There are two ways to connect the mobile phone/computer, wired connection and wireless connection. WiFi receiver works for a wireless connection. A wired connection is recommended. Because the limitation of wireless connection is that once you connect the mobile phone/computer and the projector through the wifi receiver, the mobile phone/computer will not be able to use the wifi network, but only the data network. (Because the wifi network channel of your mobile phone/computer is occupied by connecting projector via wifi) Any questions, please feel free to contact with our customer service. Here is email address of customer service: AuKingDirect@outlook.com Sincerely AuKing
