This issue is not linked to any Router Model or for that matter any settings like WPA/WPA2 or IPV6 or any other router / Ubuntu kernel version, I connect to 15 diffrent WiFi routers from time to time and have faced this issue with my hardware and there is no solution that I have come across.
I like Ubuntu and the only thing that has worked for me is downgrading to the version where my hardware is compatiable.
