4 tips to help you protect your home Wi-Fi network from strangers


Cybercriminals are always looking for unsafe Wi-Fi networks, using them to attack connected devices, stealing personal information, or downloading illegal files through your router, and to avoid all this you should make sure your Wi-Fi network is well protected.

Here are 4 tips to help protect your home Wi-Fi network from strangers:

1. Check the devices connected to your network:

If you want to protect your home Wi-Fi network, the first step is to find out which devices are connected to that network, and exclude unknown devices, to do so, follow the following steps:

  • Make sure your computer is connected to your router, whether wirelessly or cable.
  • Open your computer's web browser, and type the IP address of your network in the address bar.
  • After you access the router settings page, go to the Connected devices section, which shows you all devices connected to the router, which you usually find arranged by IP address, device number, or name.
  • Here you can scan your connected devices, such as your computer, phone, or tablet. If you can't select specific devices, turn off the Wi-Fi connection for each device one by one to discover your non-affiliated devices.
  • If you turn off all your devices and see that an unknown device is still connected, remove it immediately.

Alternatively, you can use a program to do this automatically, such as the free Wireless Network Watcher, which automatically scans the Wi-Fi network and tells you about connected devices, so you can turn it on whenever you want to check or make it work to monitor the connected entity in real-time.

2- Protect ing wi-fi network against unauthorized users:

Even if you check your network-connected devices, you may find some intruders, or you may not find them, in both cases, you can protect your Wi-Fi network by encrypting the connection, where most routers offer many options for encrypting the connection.

Instead, look for devices that offer a type of encryption that starts with WPA2 or WPA2-PSK AES, which allows you to encrypt Wi-Fi and keep hackers or cybercriminals away.

3- Changing passwords:

If you find someone stealing a Wi-Fi connection, the first step to prevent this is to enhance the router's security procedures, by adding a strong and complex password, changing the default network name, and once these procedures are applied, disconnect all your devices, restart the router, and reconnect your devices again. If you have an old router that doesn't support security features like this, it's time to consider buying a new router.

4-Creating a special network for guests:

Friends and family always want to use Wi-Fi during your visit, but to keep your devices safe away from their devices, you can create their own network or guest network in your router.

This way you can share your Internet connection with your guests while keeping them away from your main network, preventing them from seeing shared files and services, and to avoid confusion with your main network, set up (guest network) using a different network name (SSID) and a different password.

However, you must maintain the same level of security in your main network, which means creating a strong password, restricting access to shared files and devices, and making sure that local access is set in OFF mode that will prevent guests from tampering with your system.
