    Setting Up a Guest Wi-Fi Network on Your Router

    A guest Wi-Fi network lets visitors connect to the internet at your home without ever knowing your main Wi-Fi password — keeping your personal devices safer.

    1

    Find your router's admin page address

    ~20s
    On Windows, press Windows key + R, type "cmd" and press Enter. In the black window, type "ipconfig" and press Enter. Look for the line that says "Default Gateway" — the number next to it (like 192.168.1.1 or 192.168.0.1) is your router's address. On Mac, go to System Settings > Network > Wi-Fi, click "Details," and look for "Router."
    2

    Log into your router

    ~35s
    Open a web browser (Chrome, Edge, or Safari) on your computer. Type the router's IP address in the address bar at the top and press Enter. A login screen will appear. The default username and password are often printed on a sticker on the back of your router — common combinations are admin/admin or admin/password. Change this password if you never have.

    Warning

    If you cannot find your router's login credentials, look on the label on the back or bottom of the router. If they have been changed and you do not know them, you may need to factory-reset the router — which will also disconnect all your devices and require reconnecting them.

    3

    Find the Guest Network settings

    ~15s
    Once logged in, look for a menu labeled "Wireless," "Wi-Fi," "Guest Network," or "Advanced Settings." The exact location depends on your router brand — Netgear, Linksys, TP-Link, and Asus all have slightly different layouts. Click into the Guest Network section.

    Enable and configure the guest network

    ~33s
    Turn the guest network on with the toggle or checkbox. Set a network name (SSID) for the guest network — something guests will recognize, like "YourLastName_Guest." Set a Wi-Fi password for it. Make sure the option "Allow guests to access local network" or "Allow access to intranet" is turned OFF — this keeps guests off your main home network.

    Quick Tip

    Set the guest network's password to something you can share verbally or write on a piece of paper by the router. It does not need to be as complex as your main password since it only grants internet access, not access to your files.

    5

    Save and test

    ~20s
    Click "Save" or "Apply" in the router settings. The new guest network may take 30 seconds to appear. On your phone or a guest's phone, look for the new network name in the Wi-Fi list. Connect with the guest password and confirm the internet works. Then confirm that your home computers and shared folders are not accessible from the guest network.

    A guest Wi-Fi network is a separate wireless network that runs on the same router as your main home Wi-Fi. Guests connect to it and get internet access, but they are kept separate from your home network. They cannot see your personal computers, printers, smart home devices, or shared files — even if they are on the same physical internet connection.

    Why use a guest network?

    Your main Wi-Fi password protects everything on your home network. If you give that password to every visitor — a friend, a repairperson, a house guest — you are giving them access to your entire network. A guest network solves this by providing a separate "lane" for visitors that goes only to the internet, not to your home devices.

    Guest networks are also useful for smart home devices (smart bulbs, TVs, voice assistants) that do not need access to your personal computers. Keeping those devices on a guest network limits the damage if one is ever compromised.

    How to set it up

    You set up a guest network through your router's settings page, which you access through a web browser on your computer. Most routers support guest networks — you usually need to log into the router's admin panel, find the "Guest Network" or "Wireless" section, and turn it on.

    Finding your router's IP address

    On Windows: open a Command Prompt, type `ipconfig`, and look for "Default Gateway" — that is your router's IP address, usually something like 192.168.1.1. On Mac: open System Settings > Network > Wi-Fi > Details, and look for the Router IP.

    Giving it a name and password

    Choose a friendly name for the guest network — something like "SmithHouseGuests" — and set a strong but simple-to-share password. You can write it on a card near your router so guests can connect without asking you each time.

    Quick Tip: Most modern routers — especially those from Xfinity, Spectrum, AT&T, and Eero — have companion apps that make setting up a guest network much easier than using the browser-based admin panel. Check if your router has an app first.
