MC7455 disconnections every 4h

I’m using a MC7455 on a RouterBoard RMB11G flashed with Rooter fw.

Everything works fine, but i’ve a very annoying issue caused mainly by my Italian Provider.

Every 4h thay renew the IP…so…the connections test fails and modem restart…

This take sometime…and because i use this modem for business…somethins happen during some meeting…

Is there any AT command, to be used in order to avoid to lost the connection with the provider when the IP is changed?

Many thanks in advance.


I guess the data channel needs to be re-established once IP is changed
