Windows 10: Devices won't connect to wifi

So I just got a new laptop and I haven't been able to get it to connect to the wifi at all.
When I click the wifi to connect to it, put in the password, hit connect, it simply tells me "can't connect to this network".
I've tried moving it closer to the router and nothing. When I plug it directly into the router for a wired connection, it connects just fine. It's only when trying to use the wifi connection that it won't connect.

The same problem is occurring with a Roku that simply won't connect through the wifi.

Yet, other devices connect just fine such as phones, another laptop, and a desktop computer.

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.
