Na maior parte, minha rede sem fio funciona perfeitamente bem. Mas cerca de uma vez por dia, em momentos aleatórios, sou desconectado e a autenticação do chaveiro da minha rede sem fio é exibida. Todas as informações corretas são inseridas no chaveiro, mas quando clico em conectar, não consigo reconectar à rede e a janela de autenticação aparece novamente. A rede está funcionando bem e este é o único computador afetado. Isso é corrigido reiniciando meu computador, mas é uma máquina de produção, então ter que parar o que estou trabalhando e reiniciar é bastante frustrante.
Aqui está a tela que aparece:
A placa wireless é uma D-link Xtreme N DWA-552
Aqui está a saída do log quando o problema acontece:

Por favor ajude!
ATUALIZAÇÃO: O VLC parece tornar esse problema mais frequente. Isso ocorria apenas uma vez por dia em condições normais, mas quando eu estava executando o VLC ontem, ele travou várias vezes em um período muito mais curto. Não tenho certeza se isso está relacionado, mas é muito estranho ...

Também tenho esse problema no meu MacBook 2.1. Não há muito que você possa fazer a respeito, mas você pode redefinir o módulo e pelo menos ele funcionará novamente.
sudo sh -c 'rmmod ath9k; restart network-manager; modprobe ath9k'
