Indoor Cam E220 losing Wifi connection

My Indoor Cam E220 repeatedly lost Wifi connection and was replaced by Eufy under warranty with a reconditioned product. After just 2 weeks the replacement has also lost Wifi connection, leaving me with no confidence in the product. All other Wifi connected devices work normally. Have others experienced this problem? Grateful for any suggestions to improve stability.

Well, either the replacement is defective or something is interfering with its connection to your Wi-Fi.
Any new devices nearby?

Try moving it to another location for a day to see if it stays connected.

You could try changing your Wi-Fi channel to see if that solves the problem.
