Adding a Wi-Fi connection to the Outdoor Kiosk is an option that must be requested when ordering the kiosk.
Adding a Wi-Fi connection to an Outdoor Kiosk after the fact is not recommended. While there are available USB ports where you could plug in a Wi-Fi module, without an external antenna the signal would be poor and unstable. Installation of an external antenna would require modification to the kiosk and appropriate hardware to prevent ingress of moisture. Contact Advanced Kiosks if you have more questions, or discuss options for adding this.
