The GS911wifi unit requires an internet connection to execute the service functions from a cloud server. When it is set up for D2D functioning, the device itself is set up as the access point and cannot have an internet connection at the same time. You have to configure the unit for Infrastructure mode so that it can connect to the internet via a Wifi access router or via a smartphone set up as an internet hotspot.
For more information in setting up Infrastructure mode have a look at the instructional videos and read this article.
Alternatively, if you do not want to be reliant on an internet connection, you can download the standalone PC application using the download utility from our download page. The PC application will enable you to perform service functions without having to have an internet connection.
