Hi Bjorn,

I am not sure whether the modem send IPV6 packet, how do I check this?

I also reproduce this issue again. plugin 6 MC7430 with 3 SIM card, connect WIFI,  the device do live about 12 hour with 400k/2s, this issue happen.

I also attach qmi_wwan driver source code, could you check it and whether can find any clue about this issue? the uncompress command is "tar zxvf my_qmi_wwan.tar.gz"

I am very appreciate all your notice on this issue.


Best Regards,
