DHCP client and MC7304

[Westerhoff, Vincent]

Hi,

I use also MC7304 and it works fine in a similar scenario. I always get a disconnect event and re-establish automatically. I also use udhcpc.

Subject: DHCP client and MC7304

Hello,

I have an issue with my modems changing IP address, when the modem is travelling and shortly looses connection. After the connection is restored, the modem has a new IP address. 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.

I'm using udhcpc. Would it help to replace it with dhclient? Is the DHCP protocol / qmi_wwan able to handle this scenario at all? 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?

Thank you!

Kasper
