sahirhussain, Jul 17, 2016 : i have 3 oneplus 3's in my house and all 3 have a problem connecting to wifi at my house. all my other wifi devices can connect and work fine but all our OP3s keep disconnecting every 2-3 minutes and display an exclamation mark on the wifi icon. 3.2.1 made the situation worse so i downgraded my phone to 3.1.2 but the problem still persists. it seems that the wifi software or the wifi radio is pretty sensitive to fluctuations in network and simply chooses to disconnect even at the slightest hint of a disruption while other devices can neglect that minute fluctuation and maintain a connection. I have tried multiple wifi connections and mobile hotspots to confirm my findings. @Adam Krisko @Carl UPDATE those experiencing wifi problems please do this and report back. check aggressive wifi handover settings in developer options.
