Run the checks in a safe order
Use the checks below from a device connected to the local network. Keep notes of the IP, browser error, Wi-Fi network name, and whether another device behaves differently.
- Back up settings or screenshots before changing passwords, DNS, DHCP or NAT.
- Test from another phone or laptop before changing router settings.
