Dear Sir,
Thanks for your inquiry in Quectel forum.
About your issue, it is better to check the module’s network card name firstly, and confirm whether the following information.Thanks!

nmcli con show

nmcli connection show eth0

nmcli device status

systemctl restart network

nmcli connection reload

Hi,
after connecting EC20 module to main board , i am getting a module interface without doing
anything. I think these is because of ECM mode .
how to disable these interface ?

log :-
cdc_ether 1-5:1.4 enp0s21f0u5i4: unregister ‘cdc_ether’ usb-0000:00:15.0-5, CDC Ethernet Device

Dear Sir,
Whether you have use any tool to dial up ? About your issue, it seems like that you have not dial up, the module USB network card driver have installed and enumerate successful. So please double check it. Thanks!
