Pode ser algum bug do driver. Vc pdoe tentar desabilitar o CTS/RTS do AP? As vezes é um bug só nessa função.

Bom Dia, alguém já consegui fazer funcionar o wifi do Vostro 1000 (BCM94311MCG) com o Fedora 8? O meu problema é o seguinte, consigo me conectar mas depois de algum tempo (1 1/2 aproximado) a conexão cai, e de jeito nenhum volta, alguém tem alguma ideia do que possa ser? Pelo que eu no dmesg, parece algum pau no DMA da placa, segue saida do dmesg, obrigado.
