I don't know why is doing this but my wi-fi does't want to work. Yesterday wi-fi disconected from every network and in settings show me that i don't have any wi-fi network to connect. After a few hour i wanted to connect to a wi-fi network but when I entered in wi-fi settings the phone blocked...I rebooted in recovery and cleared cache and the problem was solved yesterday. Today I have the same problem but clearing the cache wasn't a solution. Now I can't acces wi-fi and it doesn't connect to any network. In attachments are 2 screenshots with what happen when I want to enter in wi-fi settings. Can anyoane please help me with this problem?
