Cyber criminals are always looking for unsafe Wi-Fi networks, as they use it to attack connected devices, steal personal information, or download illegal files through your router, and to avoid all of this, you must make sure that your Wi-Fi network is well protected.
Here are 4 tips to help you 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 steps are to know which devices are connected to this network and to exclude unknown devices. To do so, follow these steps:
- Make sure that your computer is connected to your router, either via wireless or cable.
- Open a web browser on your computer, and type the IP address for your network into the address bar.
- After entering the router settings page, go to the Connected devices section, which displays all the devices connected to the router, where you will usually find them arranged by IP address, device number, or name.
- Here you can run a scan of your connected devices, such as a computer, phone, or tablet. And if you cannot identify specific devices, turn off Wi-Fi connection for each device one by one to discover devices that are not of yours.
- If you’ve turned off all of 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 program, which scans the Wi-Fi network and tells you which devices are connected to it automatically, so you can run it whenever you want to check or make it work to monitor the connected party in real-time.
2- Protect the Wi-Fi network against unauthorized users:
Even if you check the devices connected to your network, you may find some intruders, or you may not find them, in either case, you can protect your Wi-Fi network by encrypting the connection, as most routers offer several options to encrypt the connection.
But avoid routers that offer WEP encryption that is outdated and easy to circumvent. Instead, look for devices that offer an encryption type that starts with WPA2 or WPA2-PSK AES. These protocols allow you to encrypt the Wi-Fi network and keep away Hackers or cybercriminals.
3- Change passwords:
If you find someone stealing your Wi-Fi connection, the first steps to prevent this are to reinforce the router’s security measures, by adding a strong and complex password and changing the default network name. Once these measures are applied, disconnect all your devices, and restart the router, Then reconnect your devices again. And if you have an old router that doesn’t support security features like these, then it is time to consider purchasing a new router.
4- Create a private network for guests:
Friends and family always want to use the Wi-Fi network during your visit, but to keep your devices safe and away from theirs, you can create their own 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. To avoid confusion with your main network, set up the Guest Network using a different SSID and password.
However, you must maintain the same level of security as your main network, which means creating a strong password, restricting access to shared files and devices, and making sure local access is set to OFF which will prevent guests from messing with your system.
