My MC7304 modem disconnects after more or less 24h. It is not the usual DHCP issue, because the link disconnects within a lease time of dhclient. If you set up a connection again, the problems are solved again for more or less 24h.
In pastebin I attached the logs of libqmi and ModemManager. It contains the RAW QMI messages as well the translated versions. I try to figure out why the modem after 24h disconnects
This is a link to the log: http://pastebin.com/iTDGqxnj
Till line 50: Everything goes well, ModemManager polls the signal strength. This goes on for 24h. I left one in as an example
From line 50: From this message onwards, the connection gets killed.
This behavior happens on two different mobile operators.
These are the versions I am using:
What is going wrong in the QMI messages an how can I fix it?
