If setup fails or the Tapo P304M will not join your Wi-Fi, these are the checks from Tapo’s own setup guides.

What This Problem Means

The Tapo P304M cannot finish setup, so it does not appear in the Tapo app.

Common Symptoms

• Setup fails partway
• Your network is not listed
• The device is not found

Safe Checks You Can Try

1. Use 2.4GHz Wi-Fi

Tapo’s plug setup guide says its plugs use 2.4GHz only. Tap Rescan, or choose Other Network if your network name is hidden. Tapo suggests router channel 1, 6 or 11, a 20MHz width and WPA2.

2. Start fresh

Update the Tapo app, reboot the router and the plug, check you picked the right model, and power on one device at a time.

3. Check the password

Check the Wi-Fi password, forget and rejoin the network on your phone, and update the router’s firmware.

4. Check the router limits

Tapo says some routers limit the number of clients, especially guest networks.

5. If pairing fails

Tapo suggests trying a mobile hotspot, updating the plug’s firmware, turning off the router’s firewall for a test, and resetting the plug. If the plug says “Local Only”, set the router’s DNS to 8.8.8.8 and 8.8.4.4.

6. Try another phone

If none of that works, try setting it up from a different phone.

When To Contact Support

If none of these checks fix it, contact Tapo support through TP-Link’s UK support site, with the model and hardware version from the label on the device.
