Internet no Ubuntu 14.04 vai rápido e depois lento

Question

Eu já fiz essa pergunta algumas vezes antes, mas infelizmente não consegui encontrar uma resposta.

Eu tentei consertar minha internet com o Ubuntu 14.04 várias vezes, mas acho que precisarei de uma correção específica para o meu sistema.

Vai rápido por um tempo, e então vai ficar muito lento e não voltar por um tempo.

Eu tenho um laptop HP:

Aqui está o que diz quando eu executo o lshw: Código:

Answer 1

Tente fazer o ping do seu roteador sem parar (a cada segundo ou mais rápido) e veja se ele está ficando atrasado (atrasos).

O seu router deve sempre responder-lhe rapidamente, dentro de 2 ou 3 ms. Se a velocidade diminuir ao mesmo tempo que todo o tráfego da Internet, diria que aponta para um problema sem fio (recepção) ou um problema no roteador (o excesso de tráfego p2p pode acontecer).

E se o ping do seu roteador nunca diminuir (sempre de 2 a 3 ms), o atraso estará em algum lugar além do roteador.

Outras ideias:

• Experimente um adaptador de Wi-Fi diferente
• Experimente um roteador diferente?
• Compre & amp; instalar cabo de rede / fibra ótica?
• Compre acesso à Internet mais rápido?

Poderia ser um bug também, como este link "Vulnerabilidades fixas USN-2447-1 no kernel do Linux.Devido a uma regressão não relacionada, o TCP Throughput cai para zero para vários drivers após a atualização. "
