Ubuntu 16.04 WIFI Auto Reconnect

[bitstomake]

Firstly its worth mentioning that i've trawled the Internet and tried over 15 different ways to fix this already, thought it was worth asking here because theres probably a lot of people with similar setups.

I have a rather unstable WIFI connection (which unfortunately I cannot change). I have a ubuntu 16.04 box, and I need to find a method which automatically reconnects it to the WIFI when it disconnects, and never stops trying to do so on disconnect.  The problem at the moment is that it prompts for a password on reconnect, so I have to be there to click Connect.  Are there any new scripts, programs or ideas in 2016 to do this?

Thanks

Ubuntu uses NetworkManager with nmcli being the command line utility. You can create a cron job that runs every minute to check the status and reassociate when necessary.
