hi Aleksander,
Thanks for your reply.
i have some douts .
1) Without giving manually a mmcli commands then how we can give ? and when
NetworkManager take automatically ip from ModemManager (mmcli -b 0) and
assign to LTE interface ?
2) nmcli d output :-
DEVICE TYPE STATE
CONNECTION
wwp0s21f0u5i4 wwan *disconnected*
----
here TYPE is *wwan* coming not *gsm* , when we are running *nmcli
c add type gsm con-name quectel apn internet *command
here we are giving TYPE as gsm . is it will make issue ?
I tried lot but STATE of LTE interface not Showing *connected* ,
after running mmcli and nmcli commands.
