Para corrigir o problema, é necessário colar em sudo mv /lib/firmware/iwlwifi-3160-12.ucode /lib/firmware/iwlwifi-3160-10.ucode . Não tenho certeza se mais alguma coisa é necessária, além da reinicialização.
Eu tenho um novo laptop recentemente e desde 14.04 me recusei a trabalhar e 12.04 é um pouco antiquado Eu instalei o Ubuntu 15.04 Beta 2. De qualquer forma, eu tenho procurado e não consigo encontrar uma maneira de conectar o wifi. Ele tenta se conectar por um tempo, mas depois desiste depois de um tempo. A Ethernet funciona e o BT Hub 1 funcionou, mas não consigo mais experimentá-lo com esse hub. Hub 2 e 3 não funcionam. Eu tentei seguir este guia , mas continua tendo o mesmo problema. Eu também executei algum tipo de script em algum momento. Talvez isso signifique algo para alguém lá fora? :

O crédito vai para Jeremy por isso.
Para corrigir o problema, é necessário colar em sudo mv /lib/firmware/iwlwifi-3160-12.ucode /lib/firmware/iwlwifi-3160-10.ucode . Não tenho certeza se mais alguma coisa é necessária, além da reinicialização.
Desative o bluetooth e reinicie. Isso é o que funcionou para mim. (Intel Wireless 3160 (rev 93), kernel 3.19.0-18, Linux Mint 17.1)
Desative o bluetooth iniciando o menu Iniciar e digitando "bluetooth". Em seguida, um programa de configurações Bluetooth é exibido.
Isto: sudo mv /lib/firmware/iwlwifi-3160-12.ucode /lib/firmware/iwlwifi-3160-10.ucode não teve efeito para mim. (E nem usando 15 em vez de 10 como um comentário sugere).
Aqui está um problema sobre um bug que aparentemente é a fonte dos problemas (no meu caso, pelo menos):
[Workaround]
Boot with bluetooth turned off. If the computer boots with the bluetooth turned on, the wifi will not work, even if you first turn off the bluetooth. A restart is needed.
Agora, o próximo problema: Como posso manter o Bluetooth desativado após a suspensão? Aqui está uma pergunta sobre isso, mas ele foi fechado como muito localizado: Como definir o bluetooth para permanecer desativado após a suspensão? - I acho que não é mais muito localizada. ... Estou testando isso agora: link - editar: funcionou, assim: (isso não é exatamente o que eles postaram no fórum - parece que eu tive que mudar um pouco, e block não unblock depois do currículo)

Tive o mesmo problema com o Ubuntu 14.04 e o kernel 3.19.5 (eu sei, não suportado ... infelizmente o único kernel onde eu poderia ajustar o módulo psmouse / synaptics para trabalhar com meus Trackpoints no meu Thinkpad T450s - veja link ).
Eu tinha dois arquivos de firmware em / lib / modules: iwlwifi-7265D-10.ucode e iwlwifi-7265D-12.ucode). "lshw -c network" mostrou que o firmware = 25.16.12.0 foi carregado, mas conectar-se ao WiFi não funcionou com "tempo limite de autenticação esgotado".
Depois de remover "/lib/modules/iwlwifi-7265D-10.ucode" e copiar "/lib/modules/iwlwifi-7265D-12.ucode para /lib/modules/iwlwifi-7265D-10.ucode", começou a trabalhar novamente! Muito estranho ....
Atualizei para o 15.04 e detectei o mesmo problema.
Desativar e reativar o dispositivo Wi-Fi recuperou o wifi para mim.
Basicamente:
sudo ifconfig wlan0 down
sudo ifconfig wlan0 up
Nenhuma das soluções mencionadas funcionou para mim. Felizmente, eu corrigi o problema do wifi no meu laptop Lenovo T440p apenas atualizando meu kernel Linux para 4.x como mencionado no post abaixo - Instalar o Linux Kernel 4.0.3
