Caros, estou curioso, li que ao aumentar a velocidade geralmente o SNR tende a cair, qual seria um valor "usavel" para 14Mb ? Estou colocando os status do modem (wag200G) com firmware 1.01.06-woytekm09 (01) com dados da conexão de 8M anterior e da atual de 14 Mb, usando moduções diferentes (ate porque em função da latência ate outro dia vinha mantendo meu modem em G.dmt) ===================== ----------------G.dmt DSL Status: Connected DSL Modulation Mode: G.dmt DSL Path Mode: Interleaved Downstream Rate: 8160 kbps Upstream Rate: 416 kbps Downstream Margin: 15 db Upstream Margin: 22 db Downstream Line Attenuation: 33 db Upstream Line Attenuation: 9 db Downstream Transmit Power: 12 db Upstream Transmit Power: 18 db ----------------G.lite DSL Status: Connected DSL Modulation Mode: G.lite DSL Path Mode: Interleaved Downstream Rate: 4768 kbps Upstream Rate: 416 kbps Downstream Margin: 6 db Upstream Margin: 20 db Downstream Line Attenuation: 31 db Upstream Line Attenuation: 9 db Downstream Transmit Power: 12 db Upstream Transmit Power: 16 db ----------------ADSL2 DSL Status: Connected DSL Modulation Mode: ADSL2 DSL Path Mode: Interleaved Downstream Rate: 8189 kbps Upstream Rate: 414 kbps Downstream Margin: 9 db Upstream Margin: 32 db Downstream Line Attenuation: 35 db Upstream Line Attenuation: 9 db Downstream Transmit Power: 11 db Upstream Transmit Power: 19 db ----------------ADSL2+ DSL Status: Connected DSL Modulation Mode: ADSL2+ DSL Path Mode: Interleaved Downstream Rate: 8189 kbps Upstream Rate: 414 kbps Downstream Margin: 23db Upstream Margin: 32 db Downstream Line Attenuation: 34 db Upstream Line Attenuation: 9 db Downstream Transmit Power: 11 db Upstream Transmit Power: 22 db ----------------ADSL2+ (fast) DSL Status: Connected DSL Modulation Mode: ADSL2+ DSL Path Mode: Fast Downstream Rate: 8189 kbps Upstream Rate: 414 kbps Downstream Margin: 15 db Upstream Margin: 32 db Downstream Line Attenuation: 33 db Upstream Line Attenuation: 8.5 db Downstream Transmit Power: 11 db Upstream Transmit Power: 22 db ---------------- DSL Status: Connected DSL Modulation Mode: ADSL2+ DSL Path Mode: Fast Downstream Rate: 14330 kbps Upstream Rate: 1022 kbps Downstream Margin: 5 db Upstream Margin: 12 db Downstream Line Attenuation: 34 db Upstream Line Attenuation: 9 db Downstream Transmit Power: 12 db Upstream Transmit Power: 22 db ===================== Na verdade a conexão esta estavel, mas estou particularmente incomodado com o SNR (Downstream Margin) que alem de tem "despencado" esta oscilando eventualmente chegando a valores negativos mas se mantendo estavel na faixa de 4 a 5 DB. O cabeamento interno é todo com cabos cat5, filtros BPS ok. Alguma recomendação ? Em anexo imagem do "agora" Obrigado a todos.
