Only operate this device upon the full understanding of the devices basic operation as described in this manual. Any deviation or alteration of this product, it's appearance or specification are without consent or further notice of the company. 2 Overview The C4000LG is a high performance 2x2 Wi-Fi 6 router (802.11ax) with a VDSL2 integrated access device (IAD) with a four-port built-in it Giga Ethernet switch. The C4000LG allows wired and wireless clients to safely access the Internet. Additionally, the C4000LG includes a Gigabit Ethernet LAN port that can also serve as a WAN connection to support a either a WAN or LAN function. 3 Setup 1. Insert the power connector into the C4000LG. 5 2. Plug the power adapter into a power outlet. 3. Plug phone cable (green) into the C4000LG 6 4. Plug other end of Ethernet cable into the your home phone line. 5. Continue to the Internet connection Setup. 7 4 Internet Connection Setup (CenturyLink Home Router side) Your C4000LG can automatically detect and configure your Internet (section 4.1), or done manually (section 4.2). 4.1 Automatic Connection 1.
