The most common Wi-Fi error you're unaware of committing.

Anyone can learn technology without being a tech expert.

With dinner cooking in the oven, you're searching for extra glasses, and your cousin's child shouts (again), "What's the Wi-Fi password?" You're managing a multitude of tasks, and the last thing you need is to reveal your password.

You can easily connect with everyone by printing out the information and scanning it with your phones. However, before you do, I will guide you on how to set up a separate network to protect your personal information from little Billy's access on your devices and computers.

Be my guest

By using a guest network, you can keep your private life separate from your guests while still allowing them to access devices like smart TVs, printers, and laptops or phones if file sharing is enabled. This way, if their device is compromised, your whole network remains secure.

Modern routers allow you to create a guest network without needing technical expertise. However, it may take a few minutes, but it is achievable.

To access your router's admin console, you'll need your IP address. This can typically be found on a sticker on the bottom or side of your router. Common IP addresses include 192.168.1.1 and 192.168.0.1.

If you don’t see yours …

To find your router's IP address on Windows, open the Start menu, search for "Command Prompt," then type "ipconfig" and press Enter. Look for the line that says "Default Gateway."
To find your router's IP address on a Mac, go to System Settings > Network > Wi-Fi > Advanced > Router.

To access your router login page, open your browser and enter your IP address. Use the default credentials, which are admin/password, or check the router manual or this website for alternative options.

To create a separate network for guests, rename your main network's SSID and assign a unique, strong password.

If you have snoops in the family, you can prevent them from accessing your files or devices on your primary network by turning off the local access setting.

Someone is poking around if dedicated snoops won't stop at one closed door.

While you’re at it, a quick security check

Before you finish, take these extra steps to lock things down:

Update your router login if it's still set to the default.
Ensure your router's security by checking for software updates.

Now for the fun part

Create a QR code that connects guests to your new guest network with QIFI.org. All you need is three pieces of info.

Your Wi-Fi network name can be found on the back of your modem, in the admin console, or through your network app.
You can select WPA/WPA2/WPA3 encryption from your phone's Wi-Fi settings.
Your router password is on the back of your device if you haven't altered it yet. (Please confirm if you've changed it!)

You can order a custom sign that looks classy and point to it when someone asks for the Wi-Fi password.
