Hy.
I only have one 4g modem card, but i notice that i have two interfaces wwan : wwan0 and wwan1.
Is it normal?
Thanks by advance
It is hard to say without the full dmesg output. It is possible the device uses multiple interfaces.
hmmm, I am not seeing any wwan devices enumerated in that dmesg output. Can you also send the output of udevadm info /dev/wwan0 and udevadm info /dev/wwan1?

Hy,
Sorry to psot it only now.
I don’t know if it can influence, but i have a udev rules to rename eth and wlan.
To apply it, i reload the udev rules.
