The settings displayed in the "Connection Settings" area depend on which Internet service provider you selected.
Maintain permanently (recommended for flat rates)
If your DSL rate is not charged according to online time, select this setting. Then the FRITZ!Box is always connected with the Internet. If your Internet service provider clears the connection at regular intervals, for instance every 24 hours, FRITZ!Box restores the connection immediately.
If the Internet Service Provider clears the connection at an inconvenient time, you can reschedule this event for a more convenient period. To do this, enable the option "Delay disconnection by provider to the period between". Then select the period of time from the list.
Clear idle connection (recommended for time- or usage-based rates)
If your DSL rate is charged according to online time, you should have the Internet connection cleared whenever you are not exchanging data with the Internet to save online costs. Select the option "Clear Internet connection automatically after ... seconds" and enter the time after which an idle connection is to be cleared automatically. Now the Internet connection will be cleared automatically whenever the connected computers do not request data from the Internet for the specified period.
Specify how the FRITZ!Box is connected to the Internet access.
Select "Via the FRITZ!Box" if the FRITZ!Box is connected directly to the Internet access.
Select "Via an external modem" if the FRITZ!Box is connected to an external modem or a router.
Enter the throughput rates contracted for your line in the "Upstream" and "Downstream" fields. These values are required to secure the prioritization of your network devices.
