Windows 10: Why won't my PC connect back to my wifi?

A roommate restarted our Wi-Fi router without saying anything, now everything else connects fine but my PC refuses to. It will be connecting for minutes, connect for about 30 seconds then disconnect again. I've tried turning everything off and on again, restarted everything, messed with settings, and nothing is working.

Wifi list won´t show




Hi

my new aspire 5 all of a sudden stopped letting me open the wifi list, while i had the same provider it was allright but right now i have changed my provider and since i can´t see the available networks it doesn´t let me choose it.
I´ve already tried to update drivers, restart internet settings, save the new wifi mannualy to see if the computer could connect. but nothing provided results.
From what i can guess it looks like the problem is not in the connection, because i can connect in to my old wifi and also a ethernet cable but somethig is preventing the wifi list to appear.
