Step Details
5 Carrier registration
Check that a name of a Cellular provider is visible in the “Carrier” field. If it is
not, check signal strength and otherwise contact your simcard provider and/or
insert the simcard in a phone to double check its operation and subscription
status.
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.
7
Connection to VRM
Portal
Verify that the VRM Portal menu shows a recent last connection time. See
Settings → VRM Portal. For more details, see
the VRM Connection
troubleshooting chapter of the GX Manual .
An outdoor antenna typically increases received signal by 15 dB to 25 dB.
Note that Ethernet and WiFi connections 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 LTE. 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.
This screenshot shows how all details look when everything is OK:
What to do if the GX LTE 4G is not staying connected?
Enable the “Reboot device when no contact” configuration setting in the VRM menu of the GX device.
That will reboot the GX (and with it the GX LTE 4G) automatically if the internet connection is not
available.
