Acabei de instalar o Ubuntu no meu laptop ontem e o cartão WiFi não está funcionando. Eu tenho seguido incontáveis tópicos e soluções, mas nenhum deles parece funcionar. As soluções que encontrei neste site geralmente terminam com a necessidade de iniciar um comando make que não funciona. Este é o tópico que eu segui principalmente link . Com esta solução, a marca sempre falha. Isso é o que acontece quando eu tento fazer isso

Meu wifi está oficialmente funcionando. Eu segui o tópico que o celticwarrior postou Realtek RTL8188EE drivers no Xenial? . Depois de tentar a solução que foi postada nesse segmento tudo foi bem sucedido, mas o meu wifi ainda não estava aparecendo. Então eu tirei meu laptop para além e colocá-lo juntos novamente. Depois de fazer isso meu wifi começou a funcionar.
Verifique se o seu dispositivo é suportado pelo Ubuntu, caso contrário, você precisará usar o driver do Windows com o NDISWrapper para instalá-lo e forçá-lo a executar no Ubuntu.
Aqui estão algumas informações relacionadas a isso: link
