hey guys, i'm still in the old version of MIUI (JXDMYBD14.0), unrooted. I'm often having some problem with my wifi, but I'm not sure whether it is my wifi's problem or my phone's problem. When I connected with wifi, showed connected, it sometimes seems to be have no connection, as my whatsapp unable to deliver, fb unable to refresh and etc, this problem will only gone after i disconnect and reconnect wifi or even rebooted the phone.

yozzzz, maybe have to try that
