Eu tenho uma conexão muito lenta com a internet neste laptop (eu estou usando o Ubuntu 16.04), páginas levam horas literais para carregar e às vezes termina com "Site não pode ser alcançado", e eu acredito que seja por causa desse problema . Eu também não consigo pingar o IP do meu roteador, que é 192.168.1.254.
Todos os outros PCs da minha casa usam a internet sem problemas, até mesmo o mesmo laptop, quando inicializo no Windows, conecto sem problemas.
