Wondering about router vs modem? A modem connects your home to the Internet by translating your ISP’s signal into usable data. A router takes that data and distributes it to your devices over WiFi or Ethernet. You need both for a complete home network setup.
What is a Modem, and Why Do I Need One?
A modem is the first device in your home that gets you online. It connects directly to your Internet Service Provider (ISP) and converts the incoming signal into data your devices can use.
Here’s how it works:
- It plugs into your wall outlet via coaxial cable (cable modem for cable Internet), phone line (DSL), or fiber.
- It communicates with your ISP to authenticate your Internet connection.
- Its required by your ISP to access their Internet network.
For cable Internet users, modems that support DOCSIS 3.1, like the Hitron CODA or CODA56, are ideal for faster speeds and better streaming, gaming, or remote work experiences.
What is a Router?
A router connects to your modem and is responsible for sharing your Internet connection with all your devices via:
- WiFi signals
- Ethernet cables
Here’s what a router does:
- Distributes the Internet connection from the modem to all of your end devices (computer, gaming console, streaming, etc.)
- Connects multiple devices—phones, laptops, smart TVs—via WiFi or Ethernet
- Adds network security features like firewalls and encryption
In short, your modem brings the Internet in, and your router spreads it around your home.

A modem gets the Internet into your home. A router spreads it around to your devices.
Can I Use a Modem Without a Router?
Technically, yes—but it’s not ideal.
Without a router:
- You can only connect one device at a time
- You won’t have WiFi—just a wired connection
- You’ll lack advanced features like guest networks, parental controls, or enhanced security
That’s why most households pair a modem with a standalone router or use a modem-router combo device.
What is a Modem-Router Combo?
A modem-router combo combines both functions into a single piece of equipment. These “all-in-one” devices are often provided by ISPs.
Pros:
- Easier to set up
- Fewer cables and devices
Cons:
- Harder to upgrade individual components
- May not perform as well under heavy network load
Power users and larger households often prefer using separate modem and router units for better performance and flexibility.
How Do I Know if My Modem is Up to Date?
If your modem is more than 5 years old, it may not support the latest Internet speeds. Look for a modem with these features:
- DOCSIS 3.1 support for cable Internet
- Gigabit or 2.5 Gigabit Ethernet port
- ISP approval from providers like Comcast Xfinity, Cox, Spectrum, WOW, and RCN
Hitron’s CODA is ideal for Gigabit Internet plans, while the CODA56 offers a 2.5 Gigabit Ethernet port—perfect for bandwidth-heavy use like 4K streaming, cloud backups, and video conferencing.
How Does This Impact Real-Life Internet Use?
Choosing the right modem affects more than just connection speed—it affects your experience.
Here’s how:
- Video Streaming: Reduces buffering and supports 4K quality
- Gaming: Lowers lag and provides a stable connection
- Work from Home: Handles video calls, uploads, and VPN access smoothly
To get the most from your Internet plan, your modem should match your speed tier and support modern networking standards.
Quick Recap: Modem vs. Router
- A modem connects to your ISP and brings Internet into your home.
- A router distributes that Internet to your devices over WiFi or Ethernet.
- You need both for full home connectivity.
- Modem-router combos are convenient, but separate devices often offer better performance.
- Hitron’s CODA and CODA56 are DOCSIS 3.1 modems designed for speed, reliability, and future compatibility.
