I get home, which has great WiFi, my MotoG4 connects. After a short time, my arc goes hollow. I check the WiFi in Settings and it shows its still connected. Its not. To fix this problem, I shut off the WiFi in Settings, then turn it on again. Then its good. It does not happen all the time. Just once in a while.
Seems it only happens at home. I have 3 routers with the same SSID, on 3 different channels.
The channels are pretty clean with little interference for other houses.
