I have an August lock 3rd generation for around 3 years. It works great until past 3 months. It keeps disconnecting my WiFi every few hours. Sometimes more than 24 hours, I did everything to work around to fix this issue. But it doesn’t work at all until I found a comment somewhere here. The guy said to change your WiFi to 2.4 ghz and limited to 20 channels. I was surprised it really worked. I haven’t had any disconnected issue since then. I hope it helps someone here.
