If the Tapo P304M shows offline in the Tapo app, work through these checks.

What This Problem Means

The Tapo P304M has lost its connection to your Wi-Fi or to Tapo’s cloud.

Common Symptoms

• Offline in the Tapo app
• Voice commands stop working
• Schedules still run but the app cannot reach it

Safe Checks You Can Try

1. Check it has power

Make sure the wall switch is on for a bulb, or the socket is on for a plug or strip. A smart device needs power all the time to stay online.

2. Restart the router

Reboot the router and wait for it to come back.

3. Check the 2.4GHz band

Tapo says its smart devices only use 2.4GHz Wi-Fi. If you changed router settings, check 2.4GHz is still on.

4. Check the router limits

Tapo says some routers limit how many devices can connect, especially on guest networks.

5. If it only works on your home Wi-Fi

Tapo’s plug setup guide says a device that shows “Local Only” may need the router’s DNS set to 8.8.8.8 and 8.8.4.4.

6. Soft reset it

Tapo’s plug reset guide says holding the power button for 5 seconds does a soft reset that keeps your settings.

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.
