in the past it was possible to do an automatic reconnect with this script

für den Disconnect
curl "http://user:pw@ip/status_interfaces.php" -d "interface=wan&submit=Disconnect"
für den Connect
curl "http://user:pw@ip/status_interfaces.php" -d "interface=wan&submit=Connect"

I think this script was for versions older than 2.0.

Is there a new way to do this?

I need this, cause my provider disconnects me every 24 hours. If i start this script every day at 4 am in the morning, nobody would check, that there is a short disconnect and this is much better  :D
