Your FRITZ!Box does not support combining multiple internet connections. Therefore, your FRITZ!Box cannot be used as a multi-WAN router to establish simultaneous internet connections via the WAN interface, a LAN interface, or a connected mobile broadband modem.

Note:Only the FRITZ!Box 6890 LTE supports parallel operation via the mobile network and internet access via DSL or WAN (for example via a fiber optic modem). Downstream data rates of up to 600 Mbit/s are possible when combining LTE and DSL.
