Start here
If setup fails before joining your router, first get the plug into the correct configuration mode and make sure the phone can connect to the device/setup network.
Check these first
- Confirm correct Kasa model selected.
- Confirm config-mode LED behavior.
- Check phone Wi-Fi/permissions and whether it actually connects to the setup network.
Fix it in this order
- Put the plug into documented config mode.
- Force-close/reopen Kasa if the app is stuck.
- Connect phone as the Kasa flow instructs.
- Only reset again if config mode itself cannot be reached.
Evidence to keep
- Model
- LED pattern
- Where setup stops
Do not make it harder
- Holding reset for random durations from another model
How you know it is fixed
- Plug joins home Wi-Fi and appears online in Kasa.
If the obvious fix does not work
- Forget conflicting remembered Wi-Fi profiles if the phone keeps switching away.
- If the setup Wi-Fi never appears, reset using the exact model method.
If this still isn't resolved
- TP-Link Support
