All Tapo & Kasa Cameras

Phenomenon description:

The Tapo/Kasa camera unexpectedly loses Wi-Fi connection with the Spectrum router, and the camera reports failed to receive an IP address when attempting to reconfigure it.
Note: The relevant Spectrum router's model number is SAX1V1S, SAX2V1S, SAX1V1K, or SAX2V1K.

Workaround:

After thorough analysis, we have determined that the Tapo cameras are disregarding the IP address assigned by the Spectrum router due to the presence of an incorrect UDP checksum in the packets sent by the router. We suspect that it is caused by the recent firmware upgrade of the Spectrum router. 

We are actively liaising with Spectrum to work towards a solution, simultaneously, we have developed new firmware for this issue. It's recommended to restart the Spectrum router first and check if this operation will solve the issue, then you can refer to the following step to try the new firmware.

1. Reset your camera and reconfigure it to connect it to a new Wi-Fi network. If you do not have another Wi-Fi router to provide a new Wi-Fi network, try to enable a 2.4G hotspot Wi-Fi on your phone, then reset and reconfigure your camera with a different phone.
