Uso o Ubuntu há mais de um ano no meu Macbook Pro de meados de 2010. Instalei com sucesso drivers proprietários para um dispositivo sem fio Broadcom e nunca tive problemas com wifi.
Depois de atualizar para 18.04, o wifi funcionou perfeitamente. Então, um dia, simplesmente não aconteceu.
Os resultados do iwconfig são os seguintes:
enp0s10 no wireless extensions.
lo no wireless extensions.

Esta é uma placa wireless interna da Broadcom.
Depois de um dia inteiro de solução de problemas, decidi limpar meu computador e instalar o 16.04, visto que não tive problemas antes. Surpreendentemente, isso não resolveu o problema. Desde então, atualizei de volta para 18.04.

Gosto de testar a possibilidade de falha de hardware se um dispositivo que sempre funcionou corretamente antes parar de funcionar repentinamente. Se meu mouse ou teclado não funcionar, geralmente tento conectá-lo a outro computador. Se um dispositivo de hardware que não consigo conectar a outro computador, como um adaptador sem fio, não funcionar, tento inicializar uma sessão ao vivo com um USB ao vivo do Ubuntu. Também tiro uma foto da tela de mensagens de inicialização e a estudo para ver se consigo encontrar algo interessante sobre um possível problema de hardware. Se houver um problema de hardware com o stick de RAM, ele quase sempre será impresso na tela quando o computador estiver inicializando.
