TP-Link Tapo P100 won't connect to wifi: what to do
The plug won't connect during setup (app keeps searching or shows an error).
We could not fully consult the manufacturer's support page for this model; the steps are general and may differ in details.
Most likely causes
Router only using 5 GHz or your phone is connected to 5 GHz
- Check your router settings and make sure the 2.4 GHz band is enabled.
- Switch your phone to the 2.4 GHz network or temporarily disable 5 GHz on the router.
- Try connecting again in the Tapo app using the 2.4 GHz network name.
Wrong Wi‑Fi password or special characters causing issues
- Verify the Wi‑Fi password by connecting another device to it.
- Carefully retype the password in the Tapo app and try again.
Router hides the SSID or channel not supported
- Disable 'Hide SSID' in the router or add the network manually in the app.
- Move the plug closer to the router during setup to rule out signal/channel issues.
Router blocks new devices (MAC filtering or client isolation)
- Check the router for MAC filtering or AP/client isolation and disable these temporarily.
- Try connecting the plug again, then re‑enable the security settings if needed.
Factory reset
Warning: a factory reset erases all settings and removes the P100 from your Tapo account; you will need to set it up again.
- Plug the P100 into a socket and ensure it has power.
- Find the reset button on the plug (usually a small button or a pinhole).
- Hold the reset button for about 5–10 seconds until the status LED flashes quickly, then release.
- Wait for the plug to restart and show the setup blinking; open the Tapo app and add the device again.
Frequently asked
Does the Tapo P100 work on 5 GHz Wi‑Fi?
No, the P100 uses only 2.4 GHz. Make sure your phone and router use 2.4 GHz during setup.
What does a fast‑blinking LED mean?
It generally means the plug is in setup mode and ready to be added in the app.
Will the plug forget settings after a power cut?
Normally no; the plug keeps settings after power loss. Only a factory reset clears them.
Where should I enter my Wi‑Fi password?
Always enter your Wi‑Fi password in the official Tapo app; do not use third‑party sites or services.
