I have tried to reinstall Ubuntu and also Kali Linux v2 (2017).

The logs show some problems with wpa_supplicant package, but I was not able to fix it. I have enabled wifi by removing the hard block, but even after that, my wifi connects and works for a while, then it drops, disconnects. I just bought the laptop and installed 64bit Ubuntu latest version 17. I have problems with LENOVO legion/Ideapad Y520.
