When you have chosen to connect your Gateway to a specific WiFi network (SSID), it's not possible to connect to a different network, as long as the current WiFi is visible for the Gateway.
If you wish to connect to a different WiFi network, simply follow these 4 steps:
- Turn off the WiFi, that the Gateway is connected to - for example the router or modem with WiFi connection - or go somewhere, where the current WiFi isn't reachable and therefore not visible to the Gateway.
- Make sure that the Gateway is not connected to the internet (For example by LAN or dongle).
- Make sure that the WiFi you wish to connect to is visible to the Gateway.
- Restart the Gateway and run the setup as described in the manual.
You can find the manual in the download section.
