Estou tendo um problema recorrente com a instalação do Arch Linux: o wireless funcionará por alguns minutos e, em seguida, morrerá aleatoriamente. Quando tento reiniciá-lo através do menu wifi, sou informado de que não existem redes.
> sudo wifi-menu
:: Scanning for networks [FAILED]
> No networks found
Rodando o netcfg diretamente, eu recebo:
sudo netcfg wlan0-2WIRE555
:: wlan0-2WIRE555 up [ BUSY ] Successfully initialized wpa_supplicant
Could not set interface wlan0 flags (UP): Connection timed out
nl80211: Could not set interface 'wlan0' UP

A saída de lspci é:

Toda vez que isso acontece, tenho que reiniciar para que a internet funcione. Existe algum comando systemd que eu possa usar para reiniciá-lo manualmente? Este é um problema que posso resolver permanentemente?
Eu não tenho uma máquina de chipset Centrino, mas eu uso o Arch no meu laptop e experimentei muitos cartões e drivers sem fio.
Um pouco de googling me mostra isso:
As pessoas do Ubuntu suspeitam de um possível erro de firmware
As pessoas do ArchLinux dão um parâmetro de driver para tentar.
O firmware mais recente do Centrino pode ser encontrado aqui.
Parece também que alguns laptops têm um comutador sem fio externo. Certifique-se de que está "ligado".
