Use this when the user asks how to secure their home Wi-Fi or router ("how to secure my wifi", "secure wifi from hackers", "router security settings"), how to change their Wi-Fi password or where it is shown, whether to turn off WPS or UPnP, whether to set up a guest network for smart-home devices, "can my router or internet provider see my history at home" or "do I need a VPN at home". Also use it when they suspect their own home Wi-Fi or router was hacked ("is my wifi hacked", "is my router hacked", "someone is using my wifi"): fill in the symptom answers they gave (unknown devices, a router login that stopped working, changed DNS, redirects or pop-ups, a Wi-Fi name or password that changed, slow internet, busy router lights) and use null for anything they did not say rather than guessing. Returns a router hardening checklist ranked by impact (admin password, WPA3/WPA2-AES, Wi-Fi password, firmware, WPS, remote admin, UPnP, guest/IoT network, network name, DNS), steps already done marked, brand-specific password steps and a neutral answer on privacy and VPNs at home; when symptoms are given it adds hack signals out of 100 (100 = none of the answers point to a break-in), common causes that are not a hack and ordered first steps. Do not use to hack, crack or get into a network the user does not own, to find or watch another person, to recommend VPN or security products, or for public Wi-Fi safety (use check_public_wifi_risk). Does not scan or connect to any network; works only from what the user tells ChatGPT.
