Hello, we would like to explain to you that this microscope is currently unable to connect to WiFi. Setting up a smartphone for taking photos requires the following steps: 1 Install the phone adapter onto the microscope eyepiece, then install the smartphone onto the phone adapter and align the camera lens with the eyepiece. 2.
