Ethernet port aggregation between two devices allows your devices to treat multiple Ethernet links as if they were a single link. Combining two network connections for WAN (Internet) aggregation allows you to increase network bandwidth and provide network redundancy between your cable modem and your router if one link fails.
If you have an Internet connection with speeds over 1 Gbps, but your cable modem or router does not have a Multi-Gig or 2.5G Multi-Gig port, you might need to use WAN (Internet) Ethernet port aggregation to access the maximum possible speeds provided by your Internet connection. For more information, see What is multi-gig Internet?
The router or other device that you connect your NETGEAR Nighthawk multi-gig speed cable modem to must support Link Aggregation Control Protocol (LACP) to use WAN (Internet) aggregation. For a list of NETGEAR routers that support WAN (Internet) aggregation, see Which Nighthawk and Orbi routers support WAN aggregation?
