Windows 10: Lenovo laptop won't connect to wifi

My laptop won't connect to my wifi. I can see the network, it just says it "cannot connect" everytime I try. No other devices are having this issue. I have restarted my laptop multiple times trying to fix it, but it hasn't worked, and I have no idea where to go from here.

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.
