-| 6 | Internet connection | Verify that the Internet shows "Online". Reasons for the system to not go "Online" whilst properly registered on the Network are: 1) APN not configured, contact the network operator for details. 2) The network is a different one than the home network (ie. roaming), and the setting to permit Roaming is disabled. 3)  Signal strength is strong enough to register on the network, but not to open the data connection to the internet. 4) The GX Device is already connected to Ethernet or WiFi: they have priority over the cellular connection.  |+| 6 | Internet connection | Verify that the Internet shows "Online".

 +Note that when the GX Device is already connected to Ethernet or WiFi, these have priority over the cellular connection. Even when the available Ethernet  or WiFi connection does **not** have a good connection to the internet. There is **no** automatic detection in place which in such case switches over to the GX GSM. In more technical language: when the cellular data connection is active, it is configured with a high routing metric. This way, the Linux kernel prioritises Ethernet or Wifi when these are available.
