How to use

Place the router in a central location to optimize wireless coverage and connect the primary internet source to the WAN port or use the integrated 4G connection according to the provider instructions. Connect wired devices to the Gigabit LAN ports and attach external storage or a printer to the USB port if needed. Access the router web interface via a browser to configure SSIDs, security (WPA2/WPA3), and network segmentation. Follow on-screen setup steps or the supplied quick start guide to complete initial network configuration.

Recommendations

For best performance, assign the 5 GHz band to high-bandwidth devices such as streaming boxes and desktop PCs, and reserve 2.4 GHz for devices with longer range requirements. Regularly update the router firmware and enable strong wireless encryption to maintain network security. Position antennas vertically for broad horizontal coverage and avoid placing the router near large metal objects or thick walls that can degrade signal strength.
