Meu wifi sempre funcionou no meu Thinkpad T440p desde o Ubuntu 14.04. Eu sempre fiz atualizações de lançamento. Cerca de dois meses atrás eu notei que meu PC não se conectaria ao meu trabalho wifi mesmo que a senha estivesse correta. Ele tenta se conectar e depois falha, mas meu smartphone se conecta à mesma rede wifi.
Pensando que isso pode ser um problema com o Ubuntu, eu executei alguns comandos incluindo sudo ifconfig wlan0 down e sudo iwlwifi wlan0 power off .
Eu tive erros SIOCSI ao tentar trazer a interface wlan0 via ifconfig. Pensando que eu possa ter um problema de driver, eu reinstalei o firmware do Linux e desabilitei e habilitei o microcódigo da Intel.
Neste momento, a minha placa wireless não é sequer detectada pelo meu pc, como no lspci, lshw, lsusb, etc., mesmo com o sudo.
Um tempo atrás algumas vezes a placa wifi foi detectada no meio do uso, embora de forma aleatória, mas não encontrava nem se conectava a nenhuma rede e eu tinha 'não consegui carregar o firmware' no dmesg. A placa wireless possui wi-fi e bluetooth integrados. o bluetooth funciona perfeitamente e eu estou navegando via tethering bluetooth no momento. Eu desabilitei e habilitei wifi e bluetooth na bios, mas nenhuma mudança. Eu removi a bateria e deixei o PC desconectado por 4 horas, mas sem sorte após ligar.
Preciso de ajuda para trazer meu Wi-Fi de volta, pois parece que na inicialização o iwlwifi não está carregado.
Eu atualizei para o kernel mais recente e até mesmo para o kernel portado, sem sucesso. Eu também estou tentei backported firmware linux e pior quando eu tentei meu live drive wi-fi não funcionou neste momento.
