Não aparece nenhuma rede disponível. O estranho é que eu estava usando o Windows 8.1 e estava funcionando normalmente. Instalei várias distros Linux mas o Wi-Fi continua dando esse problema. Já tentei vários tutoriais mas sem êxito.

Boa noite,

Nada funciona nessa versão, cheia de bugs ainda....... Faça bkps de seus arquivos e instale o 16.04 ou 18.04 LTS. Vá por mim....

E o Ubuntu 20.04 LTS tem muitos bugs também?

Estava usando o Ubuntu 20.04 LTS e numa atualização o wifi deixou de funcionar. Baixei o 20.10 e ficou na mesma. Vou ver se no 18.04 não encontro problemas.

Veja o resultado do comando lspci:

Talvez o ubuntu tenha carregado o módulo errado. A princípio o módulo correto p BCM43142 seria o wl, mas o sistema pode ter carregado o b43.
