O Wireless em um Acer Aspire 1810T com um Intel 5100AGN funciona por menos de um dia, então pára de funcionar até a reinicialização [closed]

Estou executando o Ubuntu 12.04 em um Acer Aspire 1810t com uma placa Wi-Fi Intel 5100 AGN que se apresentou perfeitamente no Ubuntu 10.04. Presumi que o suporte estelar sem fio continuaria com 12.04, mas encontrei uma falha que é um impedimento: a conexão sem fio funciona como esperado inicialmente, e posso configurar conexões com o Network Manager sem problemas, incluindo minha rede doméstica WPA2-Personal, mas depois em algum momento (geralmente um número de horas, quase sempre depois de uma suspensão para a memória RAM ou hibernação), a conexão sem fio cai e não é possível reconectar. A única solução confiável é reinicializar, o que não é uma solução. Antes de abrir um bug no Launchpad, pensei em verificar se alguém conseguiu resolver esse problema. Aqui está o que eu tenho:

Problema: o Wi-Fi no Ubuntu 12.04 de 64 bits pára de funcionar no Acer Aspire 1810t (Intel WiFi 5100 AGN) depois de algum tempo, muitas vezes depois de um suspender para ram.

(nota: o problema é o mesmo quando se executa o kernel 3.2.0 de estoque)

Solução de problemas

  • não pode se conectar a APs abertos ou APs WPA2
  • uma vez que os problemas de rede começam, conectar um adaptador Wi-Fi USB com chipset Atheros resulta no mesmo problema com ambos os cartões. Este dispositivo USB é conhecido por funcionar com o Ubuntu "fora da caixa", sugerindo que não é um problema de driver iwlwifi.
  • desativar o modo "N" não funciona: "opções iwlwifi 11n_disable = 1" em /etc/modprobe.d/disable11n.conf
  • não há opção de usar o ndiswrapper para este cartão wifi (o que provavelmente é uma coisa boa!)
  • descarregando o iwlwifi antes que a suspensão não funcione: SUSPEND_MODULES="$ SUSPEND_MODULES iwlwifi" em /etc/pm/config.d/unload_modules
  • mudar para o kernel 2.6.39 (com driver iwlagn), 3.3.0, 3.4.0rc5 não funciona
  • remover o módulo acer_wmi (sudo rmmod acer_wmi) não funciona e desativa o bluetooth
  • "sudo /etc/init.d/networking restart" não funciona
  • "sudo stop network-manager & amp; sudo start network-manager" não funciona
  • "sudo rmmod iwlwifi & amp; sudor modprobe iwlwifi" não funciona
  • excluir a conexão no Network Manager e recriá-la do zero não funciona
  • usando o wicd para gerenciar a rede não funciona

Alguma idéia?
