Depois de instalar o lubuntu junto com as janelas do meu laptop, notei que minha internet sem fio não estava funcionando (a internet com fio faz). Depois de algumas horas no google e tentando vários outros métodos, ainda não consegui consertá-lo.
Eu honestamente sou um novato no Linux, mas achei que seria uma informação útil:

Se alguma informação adicional for útil, terei o maior prazer em fornecê-la.
EDITAR:
Esqueci de mencionar, mas a conexão sem fio funciona no Windows dualboot.
Possíveis duplicatas: Instalando os drivers Broadcom Wireless Eu já tentei os passos sugeridos por este post. Primeiro instalei o pacote 'bcmwl-kernel-source'. Após a reinicialização, nenhuma conexão sem fio apareceu em outro programa que eu instalei, 'WiFi Radar'. Mais abaixo na resposta, sugeriu-se também tentar 'firmware-b43-installer'. A mesma coisa aconteceu. A saída do script de solução de problemas sem fio acima foi gerada logo após essa etapa.
Ubuntu 16.04 - somente conectando-se à ethernet, não opção de wifi Eu verifiquei se o secureboot estava ligado, e não estava. Executando 'sudo modprobe wl' deu o seguinte erro: Módulo wl não encontrado no diretório /lib/modules/4.4.0-21-generic.
