D7800 - AC2600 WiFi VDSL/ADSL Modem Router

Basic WiFi routers use simple single core processors to connect WiFi devices to the Internet. Nighthawk X4S delivers a high-speed DSL modem combined with simultaneous dual-band WiFi, Quad Stream performance on each band, Multi-User MIMO, has 5 Gigabit LAN ports, and 1 eSATA and dual USB 3.0 interfaces to connect external USB storage. Using a single core processor would cause severe performance issues as various processes compete for CPU power. That's why the X4S utilizes a powerful 1.4GHz dual core processor to separate processes and prioritize high-performance WiFi connections to get maximum combined WiFi speeds up to 2.53Gbps and still has room to handle advanced features such as Dynamic QoS.
