Hello,
I would like to ask you to take following steps for troubleshooting this issue:
- Upgrade device to latest firmware, or reset your device if it is already latest. Before flashing firmware uncheck “Keep all settings”.
- Check if both mobile antennas are connected to the router;
- Check if mobile data limit is not set on the router;
- Check mobile settings (“Network -> Mobile”):
· Make sure „IPv4 only “checkbox is selected
· Try to set “PPP” connection. If “PPP” connection type is used, make sure that dial number is unchanged (*99#) or set to one, operator provided
- Check what mobile settings another device (iPhone) uses for correct connectivity. Try using same settings in router
- Make sure correct SIM card slot is selected in Network -> Mobile -> SIM Management
- If the device supports more than x1 SIM slot, try putting SIM card to second SIM slot
- Check if APN is set correctly. Entries has to be same on:
· cat /etc/config/network
· cat /etc/config/simcard
- Try restarting LTE module on Web UI menu Status > Network > Mobile or use CLI command:
· /etc/init.d/modem restart
- Try using:
· gsmctl –A AT+CFUN=0
· gsmctl –A AT+CFUN=1
If issue still persist download troubleshoot file on menu System > Administration > Troubleshoot and send it to via PM. Just, make sure that troubleshoot file is generated when the issue is present and before a reboot (So it can be seen in the logs).
Regards.
