With traditional wired networks, it is extremely difficult to steal your bandwidth. But Wi-Fi wireless signals are broadcasted beyond walls of your home or office.
The signals are broadcasted to neighboring areas within your Wi-Fi range. That is easy for hackers to gain access to unsecured Wi-Fi routers. They gain access to your internet for their advantage or even gain access to your laptops and cellphones connected to your own Wi-Fi.
Hackers usually have database of factory default username, password, and IP of the routers. This is not difficult for them to access routers with factory default settings.
First, you should change your default username and password of your router device. Create a unique password of your router with special characters, numbers, and words.
Even amateur hackers use tools to break WEP/WPA (PKS) encrypted passwords. It’s better to enable network encryption using WPA2.
Hackers also monitor open Wi-Fi name (SSID) for a target. If your router is broadcasting the Wi-Fi name. You should change and hide your router’s name (SSID name).
Even if you hide your router’s name and changed the password. Hackers can still monitor the traffic from your wifi device signals. Use filter MAC Address for an added layer of protection. Every device has a unique MAC address. You can add MAC address of all of your devices in routers settings. This way only specific devices will be connected to your Wi-Fi Network.
However, it does not guarantee security. Hacker uses tools to mimic your device MAC into their computer. This way, they can connect to your router even with MAC filtering protocols. However, hiding the router’s name, using the MAC filter and WPA password is probably the best way to secure your Wi-Fi network and deters common hack attacks on your Wi-Fi network.
