Supported throughput for the WAN port
The FRITZ!Box can establish internet connections through a DSL, fiber optic or cable modem, or it can use an existing internet connection in the network. In some cases these operating modes require special protocol stacks and packet encapsulation as well as additional security mechanisms (NAT, PPP, PPPoE, VLAN, "Stateful Packet Inspection" firewall, port forwarding, traffic shaping etc.), which leads to a reduction of the highest possible transmission rate for the "WAN" port to an expected rate of about 900 Mbit/s to 940 Mbit/s.
Important:The internet access speeds that can actually be achieved depend on all of the components involved in transmitting data. Besides the FRITZ!Box, these include the network device and its network adapter, the upstream modem or router, the internet connection, the internet service provider and the remote site in the internet.
There are no standardized methods of measurement, and the results of so-called "speed tests" vary greatly due to numerous factors influencing the results.
