Em có problem sau:
PC cài win XP Pro. Ngồi tại máy tính, ping địa chỉ card mạng của máy tính không được, nhưng ping default gateway thì được. Ngồi trên router cũng vậy, chỉ có thể ping được cổng E0 của router chứ không ping được card mạng của PC.
Xin các anh, chị chỉ em troubleshoot problem này. Xin cám ơn
