Cable the Modem Router to a Router and Use Bridge Mode

In the unlikely situation that you want to use the modem router as a cable modem only that

you can connect to an existing router or gateway, you must cable the modem router to the

router or gateway, log in to the modem router, and change its router mode setting. Changing

this setting prevents certain network conflicts that can occur when two devices on the same

network perform routing functions such as network address translation (NAT) and DHCP

(assigning IP addresses to devices on the network). This turns the modem router into a

bridged modem.

Note:

If the modem router functions as a cable modem only (that is, as a

bridged modem or in bridge mode), the modem router’s WiFi radios

are turned off.



To cable your modem router to a gateway or router and change the router mode:

1.

Connect a coaxial cable.

Use the coaxial cable that your cable company provides to connect the cable port on the

modem router to a cable wall outlet or a line splitter.

2.

Connect the power adapter to the modem router and plug the power adapter into an

electrical outlet.

The Power LED lights green.

router. In most cases, an Internet service provider (ISP) provides only one

public IP address and connecting multiple devices can cause conflicts and

can cause your devices to stop working.
