Hello! I'm using Mi3 and it was working smoothly without any problem. After I upgraded to MIUI 220.127.116.11 yesterday, however, I have been having problems with connecting to WiFi network -- it shows that my device is connected to my WiFi network but there is no internet connection. It even shows notification that my device is not connected to network, while simultaneously being connected to WiFi. It does have internet connection from time to time -- maybe about every five minutes for ten seconds or so -- then goes back to not having any internet connection. I have checked that the WiFi works just fine on any other devices -- iPhone, laptops, etc. This is a lot of trouble because I rely on my phone for communication heavily. Is there any solution to this besides waiting for another update?
