Wifi não funciona com o Ubuntu [duplicado]

Question

Atualmente, não consigo encontrar nenhuma conexão wifi no Ubuntu. Ele funciona bem no Windows 10, no entanto. Eu vasculhei a internet, mas todos os posts são extremamente antigos e eu pareço ser o único usuário com esse problema. Estou na mais nova versão lançada, 6.30.223.248. Além disso, suponha que eu tenha muito pouca experiência, porque não tenho ideia do que estou fazendo.

eu entrei     sudo lshw -C rede

Acabei de responder à mesma pergunta.

Não se preocupe, basta digitar seu terminal e entrar: sudo apt-get install firmware-b43-installer

Deve funcionar novamente :)

Diga-me se isso não acontecer
