Eu sou um usuário do Ubuntu bastante sem noção, então tenha paciência comigo. Sim, procurei extensivamente por uma resposta existente, mas nem todas elas fazem sentido para mim ou não parecem se aplicar.
De qualquer forma, instalei uma nova versão do 13.04 na minha Dell Inspirion 1721 e não tenho conexões com ou sem fio. Não há drivers adicionais disponíveis em software e atualizações.
Uma coisa interessante é que, se eu inicializar com o pendrive que eu usei para instalar o Ubuntu, a conexão com fio funciona bem e o driver da Broadcom está listado no software e nas atualizações - drivers adicionais.
Se alguém puder me indicar na próxima direção para ir, eu agradeceria muito.
