Eu tenho um M645 e o segundo botão à direita do botão liga / desliga que irá alternar o disco rígido do rfkill
Esta opção funciona em 3,13,3,16, 3,19 e 4,2
Parece estar quebrado em 4.4 mas funciona agora em 4.4.0-38
Eu tenho um laptop toshiba M645-S4112 (PSMPBU-07C01S). O fio vermelho funciona bem, mas o vermelho sem fio (wifi) não funciona. Eu tenho um Kubuntu 14.04 com kernel 3.16.0-30 genérico.

O resultado de ifconfig wlan0 up é SIOCSIFFLAGS: Operação impossível de ser desativada radiofrequência . Eu aprecio todas as sugestões.

Se iwconfig mostrar wlan0, suponho que o wireless seja detectado.
ifconfig mostra apenas as conexões ativas. Se você quiser vê-los todos ifconfig -a
Talvez você só precise ativá-lo com ifconfig wlan0 up
