Como diz o título, desde a atualização para 14.04, minha conexão Wi-Fi foi interrompida periodicamente, em seguida, caindo a cada 10min a hora. Ele não será reconectado a menos que eu traga o adaptador para baixo e faça backup. Até agora, tentei atualizar o firmware do adaptador, certificando-me de que o gerenciamento de energia está desativado.
Aqui estão algumas coisas relevantes. Agradecemos antecipadamente por qualquer ajuda!
