Why should you set up a dedicated guest Wi-Fi network?

A guest Wi-Fi network is a separate sub-network created within your router that allows guests to connect to the Internet without using your main Wi-Fi network.

In fact, the more people connect and access your main Wi-Fi network, the higher the security risk. Guest Wi-Fi helps solve this problem by providing a dedicated access path, completely separate from the system and personal devices in the house.

The Benefits of Setting Up Guest Wi-Fi: It's All About Security

Creating a separate Wi-Fi network for guests is not only a technological courtesy, but also a layer of protection for your home network. When guests share the main network password, they can, unwittingly or not, gain access to all the devices connected to your home, from computers to phones to security cameras.

In reality, threats don’t always come from intentional behavior. A single device infected with malware or accidentally visiting a malicious website while connected to your main network can be enough to expose your entire system to outside agents. Guest Wi-Fi keeps these devices completely isolated, limiting access and minimizing the risk of spreading malware.

Not only people, but also smart devices in your home can become “back doors” for hackers. Internet of Things (IoT) devices such as smart TVs, smart plugs or security cameras often have lower security levels than computers or smartphones.

So, putting these devices on a guest Wi-Fi network is an effective way to isolate risks and protect the digital control center in your home.

How to Set Up Guest Wi-Fi: Easier Than You Think

Setting up a guest Wi-Fi network may sound complicated, but creating a guest Wi-Fi network is actually very easy. Once you’re done, you’ll have a separate sub-network that can serve multiple people and devices without affecting your main system.

There are two common ways to set up guest Wi-Fi, depending on the router you use and your Internet service provider (ISP):

1. Setup via carrier app or router

Most routers today come with management apps. These apps allow you to monitor connected devices, set up access permissions, and even create guest Wi-Fi networks with just a few taps.

The process is usually as follows: open the app, navigate to “Guest Network”, name the network (SSID), create your own password, then save. Your guest Wi-Fi network is now ready.

Guests can connect to the new network just like any other Wi-Fi: select the network, enter the password, and access the Internet. For added convenience, some apps also allow you to create a QR code that you can print out or stick on the fridge, so guests can simply scan it, without having to ask for the password each time.

2. Setup directly through the router interface

If your router doesn't support the app or your ISP doesn't offer this utility, you can still create a guest network through your browser.

The steps are as follows:

Step 1:Open a browser and type in your router's IP address (usually 192.168.0.1 or 192.168.1.1). You can find the IP address in your computer or phone's network settings.

Step 2:Log in to the admin page. The default login information is usually posted on the bottom of the router.

Step 3:Go to the guest network settings, which may be under tabs like Wireless Settings, Guest Network, or Advanced Settings.

Step 4:Enable the guest network feature, set a unique name and password, then save the settings.

However, not all routers support guest networking. If you don't see this option in the management interface, whether via app or browser, your device may not support this feature.

Either way, don't forget to use a strong password for your guest network to keep it safe. A simple but effective secondary network can give you peace of mind whenever guests come over, providing both convenience and security.
