Here's a short video by Ross-Tech that shows how to set-up the WiFi on a new Ross-Tech HEX-NET interface. You'll need to know the name of your WiFi network and its password


It only takes a couple of minutes to do and once you've added the HEX-NET to your WiFi, you can use it via the normal USB cable, or over WiFi by opening the VCDS options page and choosing NET in the "Select Port" (you must add the HEX-NET to your WiFi (see video guide above) before the changing VCDS to WiFi otherwise it will not be found)
