Wifi Is not working

My dear 2wappers, i have a Mi note 3 phone and its good working condition. the only problem i have encountered is that, when i start using the wifi, it shows 1-enter passowrd 2-authentication 3-password saved 4-auntencation error any expert here who can help me with this as i have rebooted my phone, factory resetted but still unale to connect... would appreciate ur help

It is a software problem so fix for that with a software update,.

its nt working, i have already updated the software

Upgrade version , merely don't reset because that update cracks .... .

Forget the wifi settings and re-enter the password & save it. Turn-off wifi then turn it on again.
