apalis-imx8-06852506:~$

In the status it shows connected, however if I try ping with

apalis-imx8-06852506:~$ ping -I wwan0 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes

I get no packets in return.

Can anyone guide me ahead of this or share any relevant resources. I am using Torizoncore on Apalix-IMX8QM.

Hi @hexagun,

After this I hope you have enabled radio and connected to cellular modem using below command

nmcli c add type gsm ifname ttyUSB0 con-name imx6 apn airtelgprs.com
nmcli r wwan on
# mmcli -m 0 --simple-connect="apn=airtelgprs.com"
successfully connected the modem

Also to further confirm check output of

apalis-imx6-04860438:~$ mmcli -b 0

Let me know after this also you are facing same problem.

The mention steps in Modem Support work well. The sim we were using had data balance issue which was sorted after which ping works.

Consider the issue solved.
