What should I do if I cannot connect the Tapo P100 to my Fritzbox router?

The Tapo app will guide you step by step during the initial configuration, but you may not be able to get through the step to connect the plug to your Fritzbox router’s Wi-Fi network. In this case, it’s suggested to do the following troubleshooting.

Change the wireless security type of your 2.4G host network to WPA2 (CCMP). Here is the link for your reference.

Note: after you successfully set up the plug, please upgrade the firmware of the plug on the Tapo app, and then you can change the WPA mode back to the one you want.

Ensure you have selected the correct home Wi-Fi network and have entered a correct wireless password. If the Wi-Fi network or password is incorrect, click on “Choose a Network” and select the Wi-Fi network again.
Make sure your smart device is within the Wi-Fi range of your router.
Turn your phone’s or tablet’s Bluetooth off and back on.
If the problem persists, try to reset the smart device as per UG/QIG, and then set it up again.
Check if there is a firewall on your router. If yes, please turn it off.
