A perda de pacotes / alto ping com um computador parece afetar toda a rede

Navegue suas respostas
0

Estou com um problema no meu PC. Eu tenho uma caixa de combinação roteador sem fio / modem que foi fornecida pelo meu provedor e estou tendo problemas com um único PC na minha rede.

O PC está conectado via WIFI e frequentemente experimentará perda significativa de pacotes e pings muito altos esporadicamente. Outros itens na minha rede estão bem. Eu tenho uma Apple TV, alguns iPads / Phones e alguns laptops. Meu computador desktop principal está conectado sem fio.

Se eu não estiver usando o PC, a rede está bem. No entanto, às vezes, quando ligo o PC, ele causa perda de pacotes (50%) ou mais, e geralmente faz com que toda a rede falhe por um período. Às vezes, parece que a reinicialização resolve temporariamente o problema ou desabilita e reativa a placa de rede. ( link )

Estou com dificuldades para diagnosticar o que pode causar tal problema. Eu sou um novato em rede, mas entendo os termos básicos. Obrigado por qualquer ajuda que você possa fornecer!

Abaixo está um exemplo de um teste de ping para o google:

Você pode estar recebendo "ping inundado". Se você estiver baixando programas, existe a chance de ter encontrado um arquivo corrompido. Seu laptop pode ter código malicioso escondido em um arquivo de programa do Windows que a maioria dos programas anti-spyware ou malware não detectará. Eu suponho que você está executando o Windows, então tente isso e veja se ele limpa o seu sistema. É um programa da Microsoft gratuito e seguro, sem lixo adicionado ( link ) Além disso, verifique as configurações do firewall e abra as portas. Você pode rastrear um endereço IP de um host de sites para ver se um navegador da web ou um programa em seu laptop aciona as portas para se tornar ativo causando comportamento indesejado. Aqui está outra ferramenta do Windows para observar as portas e a atividade on-line ( link )
