How to Boot an Unknown Device Off Your Network

Have you ever noticed a strange device connected to your home Wi-Fi network and wondered what it was? It can be a bit spooky, but don't worry! This guide will walk you through how to identify unknown devices and, more importantly, how to boot them off your network and keep them off.

Finding the Culprit

The first step is to figure out what that mystery device is. Thankfully, your router, the little box that gives you Wi-Fi, usually keeps a list of all connected devices. You'll need to log in to your router's administration page to see this information. You can usually find the instructions for how to do this in your router's manual, or by searching online for your router brand and model.

• Look for a sticker on your router that might have the administrator's website address (often something like 192.168.1.1 or 10.0.0.1) and login details.
• Check your router's manual or the manufacturer's website for default login information if you haven't changed it (though you should!).
• Once logged in, look for a section called "Connected Devices," "Device List," or "DHCP Clients."

Understanding What You See

Once you're in your router's settings, you'll see a list of devices. Each device will usually have a name (sometimes generic, like "unknown device"), an IP address, and a MAC address. The MAC address is a unique identifier for each piece of network hardware. You might need to do a little detective work to match these up with devices you own.

• Check the names of the devices – many will clearly say "MyPhone" or "LivingRoomTV."
• Compare the MAC addresses on your personal devices (like your phone or computer) to the list on your router. You can usually find a device's MAC address in its network settings under "About" or "Hardware Info."
• If you see a device you don't recognise, especially one with a generic name, this is your prime suspect.

Kicking Them Off Your Network

So, you've found an intruder! Now it's time to show them the door. Your router's administration page should have an option to disconnect or block devices. This might be labelled as "Block," "Deny," or even a "Remove" button next to the device in the connected devices list.

• In your router's settings, navigate back to the "Connected Devices" or "Device List" page.
• Find the unknown device and look for options to "Block," "Remove," or "Disconnect." This will stop it from using your Wi-Fi immediately.

Changing Your Wi-Fi Password (Crucial Step!)

Simply kicking a device off isn't usually enough, as they might be able to reconnect if they still know your Wi-Fi password. Changing your Wi-Fi password is the most important step to prevent unwanted guests from coming back. Make sure to choose a strong, unique password.

• In your router's settings, look for a section like "Wireless Settings," "Wi-Fi Security," or "WLAN."
• Find the option to change your "Wi-Fi Password" or "Pre-Shared Key (PSK)."
• Enter a new, strong password and save your changes. Remember that all your legitimate devices will need to be reconnected with the new password.

Enable a Guest Network (Optional, but Recommended)

To make things easier for visitors without compromising your main network's security, most modern routers offer a "Guest Network" option. This creates a separate Wi-Fi network with its own password, isolated from your main network. This means guests can get online, but they can't see or access your other devices.

• Look for "Guest Network" or "Guest Wi-Fi" in your router's settings.
• Enable the guest network and set a separate, strong password for it.
• When friends or family visit, give them the guest network password instead of your main one.

Keeping an Eye Out

It's a good habit to periodically check your router's connected devices list, perhaps once every few months. This helps you stay on top of who (or what) is using your internet and ensures your network remains secure. Staying vigilant is key to maintaining a safe home network.

Key takeaway

By regularly checking your connected devices, changing your Wi-Fi password when needed, and considering a guest network, you can keep your home Wi-Fi secure and ensure only the devices you trust are online. A little bit of attention goes a long way in protecting your digital space.
