Enquanto aprendia a usar meu roteador Cisco 851W, baixei um script de configuração com configurações pré-configuradas. Eu corri isso do roteador e agora não consigo mais inicializar e chegar a um prompt de comando.
Eu tentei segurar o botão de redefinição enquanto ligava o roteador novamente, mas acho que não há arquivo válido em flash porque ele continua carregando a configuração da NVRAM.
Aqui está a saída durante a inicialização. Na última linha, congela e não posso mais fazer nada. Alguma idéia de como se recuperar disso?

Acabei descobrindo que Putty não estava me permitindo ver a tela de login. Eu instalei o SecureCRT e o prompt de login apareceu imediatamente. Estranho, pois estou usando exatamente as mesmas configurações em ambos os programas (9600 baud, 8 bits de dados, sem paridade, 1 bit de parada).
Use o método de recuperação de senha explicado aqui, mas, em vez de recuperar a senha, exclua a configuração de inicialização. link
