X8 uses Smart Connect to optimize WiFi performance by intelligently assigning every device to the fastest WiFi band possible and doing so allows devices to connect at their maximum speed.
The router uses load balancing to distribute WiFi connections among all three WiFi bands, to ensure that both the WiFi bands are utilized. Load balancing prevents overloading a single 5 GHz band and ensures that both the WiFi bands are utilized and device connections are spread across the two bands.
Dynamic QoS resolves Internet traffic congestion when you have competing Internet demands at home. Dynamic QoS identifies your online activities by application and device, and then utilizes bandwidth allocation, and traffic prioritization techniques, to automatically allocate more bandwidth to latency sensitive applications like online gaming and video streaming, while ensuring that lower priority applications continue to work.
Netgear moved the WiFi amplifiers from their usual location, on the router's motherboard, to the top of the antennas. These Active Antennas help improve WiFi performance by amplifying signal in the antenna itself. This allows the router to receive cleaner and stronger signals from your mobile devices, avoiding signal degradation between the antennas and motherboard.
Six Gigabit Ethernet LAN ports allow you to connect even more wired devices. Two of six Gigabit Ethernet ports can be aggregated to double the connection speed to a Network Attached Storage device for 4K HD streaming or fast backups of multiple WiFi devices simultaneously.
