Windows 上的 LAN 卡有时不工作

Windows 上的 LAN 卡有时不工作

我有以下情况

MODEM +  (FE)(Cable A) --> (WAN) ROUTER (LAN)-----(FE)Cable B----COMPUTER

现在我的电脑上有两张 LAN 卡

1)CARD A is build in Motherbord
2)CARD B is NIC Realteck in PCI Slot

现在

1)If i Plug Cable B in Card A then internet works fine
2)If i plug Cable B in CARD then it does not show anything. Says cable unplugged

然后

1)If i put Cable A in CARD A or Card B then internet always works on both

我尝试更换电缆但结果相同

可能存在什么问题
