UPDATE: solução adicionada que resolveu meu problema como resposta
Não é uma questão de driver, no entanto, esse link foi útil para saber se eu uso o driver correto ou não Instalando os drivers Broadcom Wireless
e depois de uma longa pesquisa, encontrei alguém na versão antiga com um problema semelhante falando sobre a GUI é o motivo. então eu instalei o XUbuntu e achei funcionando e depois disso eu reinstalei o desktop ubuntu e resolvi o problema.
