DHCP client and MC7304

[Kasper Holtze]

Hi Vincent,

Do you use ModemManager or qmi-network?

I use the simplest form - the modem has autoconnect enabled (using 
qmicli). No ModemManager or qmi-network to handle the connection. I'm 
not listening for events, so I don't know yet if any is received.

Thank you :-)

Kasper

But the wwan0 interface still has the "old" IP address, as it has not expired, and the modem has not been disconnected from the computer as such.

Are there any other options than to continuously comparing the IP address in the modem with the one at the interface, and forcing renew of the address if they do not match?
