The NIC is used to transmit network data, of course, but sometimes I don't know why there is no IP. Excluding network cable No problem must be the reason for the NIC. Of course, there are no IP reasons, but the landlord will personally experience to share with you
1, the local link sent and received are 0, but the state is indeed connected
2, open support inside the dough IP is empty, not even a 0
3, enter the security mode of the system to find the network card under the Device Manager
4, right click on the network card to uninstall it, and restart the computer after the system will automatically install the network card driver
5, this time again in the Open Local link you will find that send and receive data.
6, click again to support you will find that the IP has obediently come back.
Note: The computer can not network, network card does not have IP.
