Realtek oferece um utilitário de diagnóstico de rede para a placa de interface de rede - procure o link "Windows Diagnostic Program" em Drivers de software & Utilitários . Existem algumas capturas de tela para o software em Software de Diagnóstico Realtek Ethernet .
O comando netstat, incluído no Microsoft Windows, oferece algumas informações limitadas. Um comando netstat -s
fornecerá algumas informações adicionais sobre erros. Por exemplo, no que diz respeito à possibilidade de um problema de fragmentação, há uma contagem "Fragmentação com falha de datagramas".

Você pode filtrar a exibição por protocolo com a opção -p
. O ping depende de ICMP para as "solicitações de eco" enviadas, para que você possa ver apenas as estatísticas do ICMP com netstat -s -p icmp
, mas isso apenas fornecerá uma contagem de erros.
c:\>netstat -s -p icmp

Há também a opção netstat -e
para visualizar as estatísticas Ethernet, que podem ser combinadas com a opção -s, mas isso também lhe dará uma contagem de erros.

Se você tiver outro cabo de rede, poderá substituir o cabo existente para descartar um problema de cabeamento como fonte do problema.
