Eu tenho alguns Cisco 1721 e um WIC-4ESW. Eu estava rodando outro roteador doméstico de empresas como meu roteador a cabo, mas decidi transformá-lo em uma ponte sem fio e usar meu Cisco extra como meu roteador. Recentemente, atualizei meu plano de serviço com meu provedor para passar de 8 M para 18 M para baixo. Depois que eles fizeram o que precisavam para o meu modem a cabo, eu não notei nenhuma diferença na velocidade. Meu provedor tem um servidor de teste de velocidade em sua rede para testar, então eu comecei a testar a minha velocidade e eu ainda estou recebendo apenas 6-8M para baixo às 2:00 da manhã.
-
Conectei meu computador diretamente ao modem a cabo e executei o teste mais algumas vezes e percebi que estava quase 18 milhões de acessos quase sempre. Eu coloquei o Cisco de volta, de volta a 6M para baixo. Tentei cerca de 3 vezes.
-
Eu verifiquei todas as interfaces da Cisco, sem erros ou algo incomum. Em seguida, usei exatamente os mesmos cabos e coloquei o outro produto das empresas no roteador, em vez de uma ponte, e executei os testes novamente ... 18M inativos, três vezes.
Alguém pode me dizer por que meu Cisco está retardando tanto as coisas?
Eu até tentei mudar do estilo antigo NAT para NVI, mas isso pareceu ainda mais lento ...
Eu também tentei alterar o endereço MAC da interface externa, pensando que meu provedor poderia estar fazendo o QOS no endereço de origem que eu estava recebendo do DHCP.
Obrigado,
Shawn
