@truscellino Yes, it's still happening for me. Tapping the network name again doesn't help the situation. Surprisingly, turning WiFi off and on again doesn't help either (I would have expected this to work). The only solution is to turn airplane mode on and off again or to reboot the phone.
I recently changed the channel my router uses and it had no effect on this issue. Good luck with your investigations. I have only one router and no convenient way to test others.
