Ubuntu 16.04 wifi não conectando

Wifi não está conectando no Ubuntu 16.04. Quando eu vou para as configurações de rede para ligar o wi-fi alternar imediatamente para voltar a desligar.

Eu tentei

$ sudo service network-manager restart

bem como várias outras sugestões, mas nada parece funcionar ...

Isso é o que eu recebi quando digitei

$ sudo lshw -C network

no terminal ...

Eu não acho que o cartão é reconhecido com ifconfig

Executar no terminal

sudo tee /etc/modprobe.d/blacklist-acer-wmi.conf <<< "blacklist acer_wmi"

e reinicie.

Acho que você está no caminho certo, cartão não é reconhecido em ifconfig . Sugiro usar ip em vez de ifconfig . Tente isso ...

ip a Isso mostrará todas as interfaces disponíveis. Seu wifi deve estar listado lá. Se estiver baixo, faça isso sudo ip link set wlo1 up .
