Meu Arch ( 3.6.5-1
) está exibindo um problema bastante peculiar: quando o wifi é configurado, todos os logs indicam que a configuração foi bem-sucedida e que a interface está ativa e funcional. No entanto, ao tentar acessar um site (ou executar ping), todas as solicitações excedem o tempo limite (apesar de essa conexão ser reportada como funcionando e sinalizar com 63% de intensidade). Isso tende a acontecer aleatoriamente depois que o laptop é ligado - depois de algum tempo a conexão geralmente começa a funcionar e não quebra até o próximo desligamento / suspensão.

Tudo o que deve ser carregado parece ser ( saída do lsmod ). Alguma idéia de como resolver isso ou qual é o problema?
