The NextLight U6 WiFi Router Series Starter Guide is a bilingual instruction manual that assists residential customers in connecting their high-performance U6 router to an existing Optical Network Terminal (ONT). The guide covers essential setup steps, including establishing the Ethernet connection between the ONT and the router’s WAN port, powering the device, and identifying the solid green status light that indicates the system is ready for use. It also provides guidance on locating default WiFi credentials (SSID and WPA-Key) for initial device connection and encourages the use of the NextLight WiFi app for network management. For further support, the manual features a QR code for a video tutorial and a link to additional self-install resources.
