1. Problem: How to improve the security of a home Wi-Fi network? Solution: To improve your home wireless network security, follow these steps: Use high-security encryption protocols like WPA3 (if supported), otherwise WPA2. Change the default network name (SSID) to something less identifiable or personal. Set a strong password combining uppercase, lowercase letters, numbers, and symbols. Disable SSID broadcasting if not necessary. Regularly update your router's firmware to fix security vulnerabilities. Use MAC filtering to allow only specific devices. Enable the router firewall and use Guest Network for visitors if available.
