Troubleshooting Guide: Tapo Camera, Doorbell, or Smart Device Going Offline

If your Tapo smart devices keep losing connection, this step-by-step troubleshooting guide covers the most common causes and fixes. The issue can stem from power supply problems, weak Wi-Fi signal, router settings, or interference — and the steps below address all of these for cameras, doorbells, plugs, and other smart devices. If the problem persists after following all steps, this page includes guidance on contacting TP-Link support with the right information.

Key Takeaways

• Always use the original power supply included with the Tapo device. Third-party power supplies can cause instability.
• Keep both the device firmware and the Tapo app up to date to ensure optimal performance and connectivity.
• For the best Wi-Fi signal, position the Tapo device closer to the router and away from walls, furniture, and sources of interference such as microwave ovens or Bluetooth devices.
• On the router, set the 2.4 GHz channel width to 20 MHz and set the channel to 1, 6, or 11 to reduce signal interference.
• If the issue persists, disabling advanced router features such as Smart Connect, Wi-Fi Optimizing, or Channel Optimization may improve stability.

How to Fix a Tapo Smart Device That Keeps Going Offline

Check the Device Power Supply

• Ensure you use the original power supply provided with the camera. Third-party power supplies may not provide the required voltage or current for optimal function.
• Try a different power socket to rule out the power instability.
• A power extension cord may also cause instability. You can temporarily remove the power extension cable and check if the camera becomes more stable. If your scenario requires an extension cord, please choose one that meets the camera’s power specifications, with a sufficiently thick gauge and adequate shielding. We are not responsible for troubleshooting issues caused by the extension cord.

Update Device Firmware and the Tapo App

Ensure both the device firmware and the Tapo app are up to date.

Reboot the Router and Tapo Device

Check that the router is working properly. Reboot the router and the Tapo device, then check whether the smart device reconnects.

Check the Wi-Fi Signal Strength (RSSI)

Ensure the Tapo smart device is receiving a good Wi-Fi signal by checking RSSI. If you have multiple Tapo devices, try swapping the locations of the unstable and working devices. If the issue is environment-related rather than device-specific, consider optimizing your network setup.

Optimize Device Placement

Optimize device placement. Position the smart device closer to the Wi-Fi router, avoiding obstacles such as walls, furniture, or appliances that can block the Wi-Fi signal.

Expand Wi-Fi Coverage

Consider a Wi-Fi range extender or a mesh network to improve signal strength throughout your home.

Reduce Wi-Fi Interference

Keep the smart device away from potential sources of interference, such as microwave ovens, Bluetooth devices, USB 3.0 devices, or baby monitors.

Fix IP Address Conflicts

If the smart device frequently goes offline, it may be caused by an IP address conflict. Assign a unique static IP to each device through the Tapo app (for cameras/doorbells) or your router settings to resolve the issue. For cameras and doorbells, refer to Set a Static IP for Your Tapo Camera or Doorbell. Note that static IP availability varies by model and firmware version. For other devices, contact your router's support team for assistance.

Optimize Router Settings

Since router settings vary by brand, please contact your router's support to optimize network stability based on your network topology. Here are some examples of optimization direction:

• Change the wireless settings on the router for the 2.4 GHz. Such as setting the channel width to 20 MHz, setting the password authentication method to WPA2/WPA3-Personal, and manually fixing the channel. Channels 1, 6, and 11 are non-overlapping, which may effectively reduce signal interference. Of course, specific wireless interference conditions depend on the environment. You can use tools like the Wi-Fi Analyzer app to check the channel graph and select the most suitable channel.
• Turn off Advanced Wi-Fi settings on the router, like Smart Connect, Wi-Fi Optimizing, or Channel optimization, etc.

Test with a Different Router or Hotspot

To determine whether the issue is router-specific, try connecting the Tapo device to a different router's 2.4 GHz network or a mobile hotspot.

Test without the SD Card

To determine whether an incompatible SD card is causing the issue, remove it and check whether stability improves. If it does, replace it with a compatible model from the approved list.

Test without Third-Party Software

To determine whether third-party software such as ONVIF or NAS is causing the issue, temporarily disconnect it and observe whether stability improves.

If the issue is still the same

contact TP-Link technical support and provide the information below for our support to look into further:

• LED status when the smart device is offline, e.g., red/green blinking/green steady, etc.
• MAC address of the device
• TP-Link ID email address
• When an issue occurs, does the smart device work in the local network? For the test, please connect your mobile device to the home Wi-Fi network at that time and verify that the Tapo device remains accessible on the local network.
• The Wi-Fi router model number and your network topology. E.g., ISP Spectrum-Archer C7 router<Wireless> Tapo device
• How often does this problem occur? How do you restore the connection, for example, by restarting the smart plug or rebooting the router?
