What You'll Need Before You Start
Setting up a home network for the first time is more approachable than it might seem. At its core, a home network consists of two main pieces of hardware: a modem, which receives the internet signal from your provider, and a router, which distributes that signal to your devices — either over Wi-Fi or via physical ethernet cables. Some providers supply a single gateway device that combines both functions.

What you will need
Modem
Translates the internet signal from your provider into a form your home network can use.
Wireless Router
Broadcasts your internet connection as Wi-Fi and manages traffic between connected devices.
Ethernet Cable
Creates a wired connection between the modem and router, or between the router and a device.
Smartphone or Laptop
Used to access the router's admin panel and verify that devices connect successfully.
Coax or Phone Line Cable
Connects the modem to your home's wall outlet depending on your internet connection type.
Step-by-Step: Building Your Home Network
Follow the steps below in order. Each one builds on the previous, so skipping ahead can lead to connection issues that are harder to diagnose later.
Router Placement Matters More Than You Think
Place your router in a central, elevated location — away from thick walls, large appliances, and enclosed cabinets. Wi-Fi signals radiate outward in all directions, so a central position distributes coverage more evenly across your home. Avoid placing the router on the floor or inside a closet.
Connect the modem to your wall outlet
Locate the cable or phone line outlet in the room where you plan to set up your network. Connect one end of the appropriate cable — coaxial for cable internet, or a DSL phone cable for telephone-line-based service — to the wall outlet and the other end to the modem's input port. Plug the modem into a power outlet and wait for its indicator lights to stabilize, which typically takes one to two minutes.
Connect the modem to the router
Using an ethernet cable, plug one end into the modem's LAN or output port, and the other into the router's WAN port (sometimes labeled "Internet"). These ports are usually a different color from the regular LAN ports to help you identify them. Power on the router and wait for it to fully boot — this can take up to two minutes.
Access the router's admin panel
From a device connected to the router via ethernet or its default Wi-Fi network, open a web browser and type the router's default IP address into the address bar. Common addresses are 192.168.1.1 or 192.168.0.1 — check the label on the bottom of your router if unsure. Enter the default username and password printed on the router or in its manual to log in.
Change the default admin password
Inside the admin panel, navigate to the administration or security settings section and change the router's login password to something unique and strong. This is separate from the Wi-Fi password. Leaving the default credentials unchanged makes it easy for anyone who accesses your network to alter your settings.
Set your Wi-Fi network name and password
In the wireless settings section of the admin panel, find the field for your network's SSID (Service Set Identifier) — this is the name that will appear when people search for Wi-Fi nearby. Replace the default name with something you'll recognize, but avoid including personal details like your address or full name. Then set a strong password for the network using the WPA2 or WPA3 security protocol if available.
Connect your devices and verify the connection
On your phone, laptop, or other devices, search for available Wi-Fi networks and select the one you just named. Enter the password you created. Once connected, open a browser and navigate to any website to confirm that your internet access is working. For devices that stay in one place — like a desktop computer or a smart TV — consider connecting them directly via ethernet for a more stable connection.
Never Skip Changing Default Credentials
Routers ship with publicly known default usernames and passwords. Leaving these unchanged means anyone connected to your network could alter your settings, redirect your traffic, or lock you out of your own router. Change both the admin password and Wi-Fi password before considering your setup complete.
After Setup: Keeping Your Network Secure
Once your network is running, your next priority should be maintaining good security habits. The steps above get your network functional, but there is more to do to keep it safe over time. Our article on home network security habits covers practical ongoing practices, and if you want a more thorough walkthrough of closing common vulnerabilities, see securing your home network without a technical background.

Fiber and Cable Setups May Differ
If your provider supplies a gateway device — a combined modem and router in one unit — the steps above may differ slightly. Consult your provider's setup guide or support line to confirm the correct connection sequence before proceeding. Incorrect setup can result in no internet access or unstable connections.
