Network & Wi-Fi Security
Your network is the road every byte of your data travels on — at home and out in the world. This section covers both ends: the public Wi-Fi you borrow at airports, hotels, cafés and stadiums, and the home router that quietly guards everything in your house.
For public networks, we explain what's actually risky in 2026 and what isn't — when modern HTTPS already protects you, and when a VPN is a sensible extra layer for privacy on a network you don't control. For your home, we give a plain 15-minute checklist: change the default admin password, use WPA3 or WPA2, update the firmware, turn off WPS and separate your smart devices onto a guest network.
Every guide draws on consumer guidance from sources like the FTC, CISA and the NSA, and stays beginner-friendly. We position a VPN honestly: useful on untrusted Wi-Fi and for privacy from the local network or ISP, but not a replacement for good router settings or account security.
