Não consigo conectar-me à rede no Scientific linux 6.9

Question

Eu instalei o linux científico 6.9 (baseado no redhat 6) no meu livro de superfície, mas ele não se conecta à minha rede sem fio. Quando eu abro as preferências do sistema + rede, ele não encontra nenhuma conexão sem fio existente e quando eu adiciono manualmente uma nova conexão de rede, ela nunca se conecta a ela. O que devo fazer ?
