Oi gente, eu acabei de trocar do windows 8 para o ubuntu 16.04lts 64bits e durante o boot do pendrive o nootebook conectou-se sem problemas a rede via o wifi porém depois ele parou a conexão e não encontrou mais nenhuma rede a não ser quando via cabo. O LED do wifi continua ligado como se estivesse funcionando normalmente. Seguindo alguns tutoriais que achei tenho as seguintes informações:
