Имеем:
DSL-2640U
На входе Стрим.
На выходе:
2 компа (XP, сетевухи DFE-520TX), ТВ-приставка, на Wi-Fi точка доступа (для ноута) и КПК.

Проблема заключается в том, что когда в рутер включены 2 компа, то через несколько минут "зависают" оба рутерных порта (лампочки горят и не мигают). Не пингуется даже сам рутер. В то же время вайфай и ТВ продолжают нормально работать.

Если включен (физически) один комп, то все ОК. Если воткнуть второй провод (даже при выключенном втором ПК), то через несколько минут пропадает связь с рутером. Потом может восстановиться сама, но будет работать только один из ПК или не будут работать оба.
При физическом выключении и включении одного из проводов или отключении и включении соединения в ОС связь восстанавливается, но не надолго. От нагрузки на сеть ничего не меняется.

От сетевых карт ничего не зависит (менялись), от настройки ОС, видимо, тоже (т.к. связь прерывается даже при выключенном ПК, но подключенном проводе).

Длина проводов - 10м каждый. Настройки рутера - по инструкции с вашего сайта. Вайфайные устройства используются редко и с ними проблем не наблюдается. На всех устройствах IP-адреса статичные, ДСЛ прописан, ДХЦП отключен.

Что посоветуете..?

Еще информация для примера:
Включен один ПК. Все ОК. Работает долго и стабильно. Рутер пингуется.
Втыкаем провод во второй ПК, который выключен. Начинает мигать линк на сетевухе - через 5 минут рутер не пингуется.
Выключаем БП на втором ПК, витую пару оставляем - на первом пинг моментально восстанавливается.
