Realtek предлагает утилиту сетевой диагностики для сетевой карты. Найдите ссылку «Программа диагностики Windows» в разделе « Драйверы и утилиты программного обеспечения» . Есть несколько снимков экрана для программного обеспечения в Realtek Ethernet Diagnostic Software .
Команда netstat, входящая в состав Microsoft Windows, предоставляет ограниченную информацию. netstat -s
Команда предоставит дополнительную информацию об ошибках. Например, что касается возможности проблемы фрагментации, существует счетчик «Datagrams Failing Fragmentation».

Вы можете фильтровать отображение по протоколу с помощью -p
опции. Ping полагается на ICMP для «эхо-запросов», которые он отправляет, поэтому вы можете посмотреть только статистику по ICMP netstat -s -p icmp
, но это просто подсчитает количество ошибок.
c:\>netstat -s -p icmp ICMPv4 Statistics Received Sent Messages 243951 46546 Errors 0 0 Destination Unreachable 19710 22409 Time Exceeded 177648 0 Parameter Problems 0 0 Source Quenches 0 0 Redirects 0 0 Echo Replies 445 23182 Echos 46148 955 Timestamps 0 0 Timestamp Replies 0 0 Address Masks 0 0 Address Mask Replies 0 0 Router Solicitations 0 0 Router Advertisements 0 0
Также есть netstat -e
опция для просмотра статистики Ethernet, которая может быть объединена с опцией -s, но это также даст вам счетчик ошибок.
c:\>netstat -e Interface Statistics Received Sent Bytes 2205957284 1335899145 Unicast packets 1239501865 433229740 Non-unicast packets 143181375 167714415 Discards 0 0 Errors 0 55 Unknown protocols 0
Если у вас есть другой сетевой кабель, вы можете заменить существующий кабель, чтобы исключить проблему с кабелями в качестве источника проблемы.
