I am working with a Quectel RM520N-GL 5G modem on Ubuntu Linux and need some clarification regarding APN configuration. The modem is getting detected in the OS, but I am facing issues when attempting to configure the APN for network connectivity.
1) Ubuntu Version Support
I am currently using **Ubuntu 22.04** LTS, and **kernel version** 6.8 and I would like to confirm whether the Quectel RM520N-GL modem is fully supported on this version.
2) Supported Data Connection Modes
After the modem is detected, in which operating modes can APN configuration be performed?
QMI mode a
MBIM mode
AT command mode
PPP/GSM mode
**3) When I try to add an APN via Network Manager, This creates the connection profile, but it does not activate properly.
nmcli connection add type gsm ifname “*” con-name rm520 apn “YOUR_APN”
- If other, provide the recommended or official method to set APN and bring up the data session.
And also provide the commands for setting APN.
