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
