Randomly, my wifi goes out and all networks disappear from the list. Refreshing does nothing, it won't scan. I have to go to Connect To Hidden Network in settings and manually type in my SSID and password again. Then it connects and the other networks show up again. If it helps, I checked install 3rd party MP3 and wifi software during installation

The installation of that custom driver failed. The output of network diagnostics is here. http://pastebin.com/P5PaXd7h
