Não foi possível conectar-se à reinicialização da unidade sem fio (nl80211)

Question

Estou usando o Samsung NP900X3C.

Eu tenho problema em conectar-me ocasionalmente ao WIFI, com o Ubuntu 12.10. Às vezes meu computador não pôde se conectar ao WIFI "blab", nem depois de reiniciar o computador.

A única solução é reiniciar o ponto de acesso WIFI. É o WIFI público, usado por muitos usuários, que não tem esse problema.

Meu /var/log/syslog :
