Fiz isso agora, vou ver se o problema volta a acontecer.
Percebi também, que o problema acontece quando estou vendo vídeos no youtube, por exemplo.

O problema se manteve, o DNS não ajudou...

Acabei de formatar e instalar o ubuntu 15.10 para ver se resolvia, e tive o mesmo problema. Acontece principalmente, quando estou vendo videos (youtube, netflix, etc..).
