Setting Up a Home Network for the First Time

What You Need Before You Start

Setting up a home network is more straightforward than it sounds, provided you gather the right pieces first. Here is what you will need:

• An internet service plan — arranged in advance with an ISP (Internet Service Provider).
• A modem — sometimes provided by your ISP, sometimes purchased separately.
• A router — often bundled with the modem as a single gateway device.
• An ethernet cable — usually included with the equipment, used to connect the modem to the router.

If your ISP ships you a combined gateway device, steps involving separate modem-to-router cabling do not apply. Check what equipment your ISP requires before purchasing anything separately.

Understanding the Hardware: Modem vs. Router

Confusion about modems and routers is extremely common. Think of it this way: the modem is the translator between your ISP's signal and your home's equipment. The router takes that translated signal and shares it wirelessly and through cables to every device in your home.

Without a router, only one device could use the internet at a time. Without a modem, the router has no signal to share. Together, they form the backbone of your home network. Many ISPs supply a gateway — a single box that combines both functions — which reduces the number of devices you need to manage.

Understanding how your internet signal travels from the street to your screen can also help you troubleshoot problems later.

Connecting and Configuring Your Router

Once you have your equipment, setup follows a consistent sequence:

1. Connect the modem to your ISP's outlet (coaxial cable for cable internet, phone line for DSL, or fiber terminal for fiber).
2. Run an ethernet cable from the modem's output port to the router's WAN (internet) port. The WAN port is usually labeled and color-coded differently from the other ports.
3. Power on the modem first, wait for it to fully initialize (roughly 60–90 seconds), then power on the router.
4. Access the router's admin panel by typing its IP address into a browser — commonly printed on the router's label along with default login credentials.
5. Change the default network name (SSID) and Wi-Fi password to something unique. This is the single most important configuration step.

Many modern routers include a companion smartphone app that walks you through these steps visually, which can make the process easier for first-time users.

Getting Devices on the Network

With the router configured, connecting devices is straightforward. For wireless devices — phones, tablets, laptops — open the Wi-Fi settings, select your new network name, and enter the password you just set. For stationary devices — desktop computers, smart TVs, gaming consoles — an ethernet cable plugged directly into the router generally provides faster, more stable performance than Wi-Fi.

If you are setting up a new device and being prompted for various app permissions during the process, take a moment before tapping through everything. Our guide on setting up a new device without oversharing covers which prompts deserve a second look.

Improving Coverage and Reliability

Even a correctly configured router can deliver inconsistent coverage if it is poorly placed. Practical steps to improve signal strength include:

• Move the router to a central location — signals radiate outward in all directions, so a central position covers more of your home.
• Elevate the router — placing it on a shelf rather than the floor reduces interference from furniture and flooring.
• Keep it away from microwaves, cordless phones, and baby monitors, which can interfere with the 2.4 GHz band.
• Consider a mesh Wi-Fi system for larger homes — mesh systems use multiple access points to blanket the home in coverage instead of relying on a single router.

If certain rooms consistently have poor signal, a Wi-Fi extender (also called a range extender or repeater) can help bridge the gap, though mesh systems generally provide a more seamless experience.

Next Steps: Security and Beyond

A working network is a great start — but a default or carelessly configured network is a security risk. At minimum, ensure you have completed these steps before considering setup done:

• Changed the router's admin login password (not just the Wi-Fi password).
• Enabled WPA3 or WPA2 encryption on your Wi-Fi network (found in router wireless settings).
• Disabled remote management if you do not plan to access the router from outside your home.
