ZDNET Flags 3 Signs of Wi-Fi Intruders, Urges Password and WPA3 Upgrades

Summary
Three warning signs can point to unauthorized Wi-Fi use: sudden slowdowns, unfamiliar devices or unexplained router activity, and repeated outages or password changes that lock the owner out.
Router gateway checks and network scans are the main ways to confirm an intruder, with ZDNET pointing users to device lists, connection logs, and tools such as Fing, Nmap, and WiFi Analyzer.
Weak passwords, default admin credentials, outdated firmware, and older security standards such as WPA can let outsiders onto a home network through guessing or brute-force attacks.
Changing the Wi-Fi password is the fastest way to boot freeloaders, while stronger admin credentials, firmware updates, WPA3 where available, and a separate guest network help keep them out.
