Tarde Tudo,
Eu tenho um laptop (HP Probook 455 G2) rodando o 15.04. Uma instalação limpa ...... estava trabalhando com 12.04 para cima .....
Uma instalação sem aparente, mas com um problema MAJOR. O Wi-Fi está ativado, mas não consigo ver nenhuma rede Wi-Fi ou conectar-se a outras ocultas. Não tenho certeza onde ir a partir daqui .... por favor, veja abaixo os resultados do que pouco comandos Linux eu sei! :)

Qualquer ajuda será apreciada com gratidão e, se conseguirmos trabalhar, faremos uma estrelinha !! :)
Não consigo responder diretamente a você com etapas detalhadas (escrevendo a partir de uma instalação do Windows), mas lá vai você:
git clone https://github.com/lwfinger/rtlwifi_new.git
e o simples compilar com
make
se tudo estiver bem, então faça
sudo make install
PS: você precisa de um kernel relativamente novo (depois de 3.18 eu acredito) e cabeçalhos para combiná-lo. Além disso, parece que o suporte ainda está apagado: mesmo laptop
