Netgear D6400 – AC1600 WiFi VDSL/ADSL Modem Router—802.11ac Dual Band Gigabit User Manual

You can view or change the modem router’s cable or fiber Internet connection settings 
manually. The following sections describe the options that are available to you to manually 
set up the cable or fiber Internet connection:

Some ISPs require that you register on their website before you can 
obtain Internet service. Follow the directions that your ISP gave you.

If you connect both a DSL modem and a cable or fiber modem to the 
modem router and you want to manually specify the settings for a 
cable or fiber Internet connection, you must first set the WAN 
connection preference manually to the Ethernet WAN port (see 

192). If 

you do not, the DSL settings take precedence over the cable or fiber 
settings. However, NETGEAR recommends that you connect only the 
modem that you intend to use for your Internet connection: a DSL 
modem, cable modem, or fiber modem.

If you want to manually configure the cable or fiber connection settings, use the information 
that your ISP gave you to connect to your Internet service. If you cannot find this information, 
contact your ISP. Entering incorrect information might prevent the modem router from 
connecting to the Internet.

The modem router provides a virtual Internet interface and a virtual IPTV interface. In most 
situations, you only need to configure the Internet interface. If you use an IPTV device, you 
might also need to configure the IPTV interface. Follow the directions that your ISP gave you.
