FRITZ!Box with cable modem reports "Internet connection renewed successfully" every 12 hours
When using the FRITZ!Box with a cable modem, the FRITZ!Box appears to clear the connection at regular intervals. Either the message "Internet connection renewed successfully" or "Internet connection established successfully" is displayed in the event log of the FRITZ!Box every 12 hours.
1 FRITZ!Box does not clear the Internet connection
Because IP addresses obtained from cable providers are only valid for a limited time, the FRITZ!Box "extends" the validity (DHCP Lease-Time) at regular intervals. Each extension is logged in the event log of the FRITZ!Box. However, the FRITZ!Box does not clear the Internet connection when this occurs.
