If you are building a new wireless network, you may wonder how to set up a modem router combo, such as the Netgear C6900 vs C7000. The best routers, after all, occasionally come packed in with a modem. So how do you connect a combination unit and what are the benefits of using one? Keep reading to find out.


  • A modem/router hybrid device combines the functionalities of both a router and a modem into one handy unit.
  • Plug the device into the coaxial cable that heads into your home, providing Internet from your Internet service provider. Plug an Ethernet cable into the Ethernet ports for any wired devices and the device into a wall outlet.
  • Power on the cable modem device and head to the settings page, making sure to change the password and wireless network name from their default options.

Why Use a Modem/Router Combo Device?

The main reason here is convenience. One gadget is easier to set up and maintain than two gadgets, after all. These combination devices include all of the functions found with dedicated routers and modems if you are learning how to know the security type of your WiFi, how to set up a dual-band router, or the differences between a router and a gateway. Additionally, many Internet service providers (ISPs) will send out these hybrid units instead of separate routers and modems to new customers.

Insider Tip

If you are having issues with either feature of one of these hybrid devices, don’t hesitate to contact your ISP.

How to Hook Up a Modem and Router Combo

The actual process may differ depending on your specific model, such as when you are learning what is a bridge mode on a router and how to access it. However, there are some universally accepted steps you can take to ensure a smooth installation and setup process.


Unbox the device and make note of the sticker on the exterior of the modem/router unit. This sticker includes pertinent information such as the public IP address, the default username, and the default password.


Plug the coaxial cable that delivers an Internet connection to your home into the relevant port along the modem section of your device.


Step 3 – Power on the router/modem and wait for both features to light up green, indicating that they are accepting and transmitting a strong signal.


Head to your computer and input the router’s IP address as found on that sticker into a web browser. You should see a login page. Enter your login credentials, including the network name and password (also on the sticker.)


You’ll find yourself on the settings page. Make any changes you think are necessary to improve performance and security. Also, take this time to change both the default network name and default password. Save your changes and exit the admin control panel.


Where to find your model number?

Find the model number on the exterior of the device itself, which could be handy when getting up connected devices to your Wi-Fi network.

What are the benefits of a modem and router combo?

The benefit is convenience, as you don’t have to keep track of two individual devices. Router combo devices are generally easier to maintain for this reason.

How to connect a router to a modem?

They need a wired connection, which is typically an Ethernet cable. Once that is done, you’ll be able to set different router configurations and complete the router setup.

STAT: Internet service providers (ISPs) often provide a modem and router combo device, also known as a gateway router. These connect you to the Internet and also create a wireless network to connect all of your home devices. (source)
