1. Access Your Router’s Admin Interface
The first step in setting up WiFi security is to access your router’s admin interface. Here’s how you can do it:
Find Your Router’s IP Address: The IP address is usually printed on the back of the router or can be found in the user manual. Common default IP addresses include:
- 192.168.0.1
- 192.168.1.1
Log In to Your Router: Open a web browser and enter the router’s IP address. You will be prompted to enter your username and password. If you have not changed these, check the default credentials, which are typically ‘admin’ for both fields.
2. Change Default Login Credentials
Upon logging in, change the default admin username and password. Keeping the default credentials makes it easier for unauthorized users to access your network. Choose a strong and unique password that combines uppercase and lowercase letters, numbers, and special characters.
3. Change the Network Name (SSID)
Your network name, known as the SSID (Service Set Identifier), is the name that appears when searching for WiFi connections. Changing the SSID from the default can help obscure your network’s identity and make it harder for unauthorized users to access it.
Tips for Choosing an SSID:
– Avoid personal information, such as your name or address.
– Use a random mix of letters and numbers for better obscurity.
4. Enable WPA2 or WPA3 Encryption
One of the most critical steps in securing your WiFi network is enabling WPA2 or WPA3 encryption. Locate the wireless security settings in your router’s admin interface, and select either WPA2-PSK or WPA3, depending on your router’s capabilities.
Additionally, set a strong passphrase for your network. This passphrase should be at least 12-16 characters long and should include a mix of letters, numbers, and symbols to enhance security.
