Yes, I deployed one last year during the summer which has been running on 4G ever since without any mayor hiccups. Firmware I used was the last release before juli 2020.
I’m using the same firmware on an LG308 with 4G connectivity (fitted in an outdoor enclosure).
i am unable to get mine to connect to 4g it just constantly disconnects, would you be willing to share your exact firmware version and a screen shot of your cellular configuration page?
I check both of the checkboxes and fill in the APN (check with your provider).
The rest I leave standard.
Maybe you can try with wifi off and ethernet cable disconnected, I noticed that any change in the network configuration will cause all network interfaces to restart.
On my gateways I’ve used firmware V5.4.1633695703 and V5.4.1666149468.
Can you log in your gateway via SSH and check the output of
logread -f
Then you can see what is going on with the connections.
