Why did all smart devices break after changing Wi‑Fi name?
IoT devices store the old SSID/password and usually need to be migrated or re-paired. Temporarily restoring the previous credentials may reconnect them if safe.
Old/new SSID; security; number of devices.
Device-by-device vendor support as needed.
