Ethernet vs Wi-Fi security comparison reveals surprising results for home users seeking protection

Ethernet relies on a physical cable for direct connection to the router, reducing the risk of data interception, while Wi-Fi transmits data wirelessly, making it more vulnerable to unauthorized access. A well-secured Wi-Fi network can be more secure than a poorly managed Ethernet setup. The security of a network depends on factors such as router configuration, software updates, and the number of connected devices. To enhance internet security, users should employ strong passwords, enable the latest encryption, keep router firmware updated, review connected devices, install antivirus software, and consider using a VPN for sensitive tasks.

Don’t use your home Wi-Fi before fixing certain security risks

Home Wi-Fi networks connect various devices and are essential for online activities, but they can be vulnerable due to weak security settings and outdated equipment. Hackers often target residential networks, which typically have weaker defenses than corporate systems. Compromised networks can lead to the interception of sensitive information. To enhance Wi-Fi security, it is important to use a modern router with strong encryption (WPA3 or WPA2), regularly update firmware, change default login passwords, and create a strong Wi-Fi password of at least 12 to 16 characters. Monitoring connected devices and disabling Wi-Fi Protected Setup (WPS) can help prevent unauthorized access. Using a Virtual Private Network (VPN) can protect online privacy, while antivirus software can safeguard connected devices from malware. Taking these steps can significantly improve home Wi-Fi security.
