Ubuntu 16.04 Wi-Fi desconectando [fechado]

Question

depois de atualizar para 16.04 meu wifi cai aleatoriamente. Muitas vezes, alguns minutos após a inicialização, mas às vezes depois de várias horas. Eu sou dualbooting Ubuntu no Microsoft Surface Pro 4.

Depois de reinstalar o sistema no Ubuntu 14.04.05, ele funciona.
