Hi,
You can try the following steps for your case.

1. Reboot the wireless router, when it has an internet connection, reboot the camera and check if it will work again.

2. Factory reset the camera if the problem remains, and then reconfigure it and check if it will work.

3. If the camera is not working, what's the LED status on the camera, and what error message appears when configuring it?

Best Regards

Hi,
Please help confirm the following information for further analysis.
1. What's the model number of your wireless router? Is the Tapo C500 connected to the router's Wi-Fi directly rather than an AP or RE?

2. When the camera is working, please go to its Device Settings>Device Info page, tap the Wi-Fi icon, and send me the specific Wi-Fi signal value(RSSI).

3. Find the IP address of the camera on its Device Info page on the Tapo app when it's working, try to ping the IP address on a PC connected to the same Wi-Fi as the camera when the camera is offline, and check if you can ping it successfully.

Best Regards
