A modern overview of wireless connections: what they do, how Wi-Fi works, current standards (Wi-Fi 5/6/6E), security best practices (use WPA2/WPA3, VPNs on public hotspots), and practical tips for home and mobile use.
Practical, up-to-date steps to protect your laptop on public Wi-Fi: use strong sign-in and disk encryption, prefer WPA2/WPA3 networks, use a VPN, enable firewalls, keep software updated, and adopt cautious habits.
Wireless internet uses radio waves to connect your device (via a Wi-Fi adapter or cellular radio) to an access point, which forwards traffic to an ISP. Speeds depend on distance, interference, hardware capability, and network congestion.
A wireless bridge connects Ethernet devices or entire LANs to Wi-Fi, enabling printers, NAS, consoles, or building-to-building links without new cabling. Modern bridges support Wi-Fi 6/6E, multi-gig Ethernet, and should be secured with WPA3 and proper network segmentation.
