2) Ping the native network card IP

3) Ping the Gateway

Wu, tracert

If you have network connectivity issues, you can use the tracert command to check the path to the destination IP address that arrives and log the results. The tracert command displays a set of IP routers that are used to pass packets from the computer to the target location, along with the time required for each hop. If the packet cannot be delivered to the destination, the tracert command displays the last router that successfully forwarded the packet. The tracert command can be used to track the routing (path) used by datagrams when datagrams are routed from our computer through multiple gateways to destinations. The path that the utility tracks is a path from the source computer to the destination, and there is no guarantee or thought that the datagram will always follow this path. If our configuration uses DNS, we often get the names of cities, addresses, and common communications companies from the resulting responses. Tracert is a slow-running command (if we specify the destination address is far), each router we need to give it about 15 seconds.

Tracert is very simple to use, only need to tracert after the IP address or url,tracert will be the corresponding domain name conversion.

The most common uses of tracert:

Tracert IP Address [-d] This command returns the list of routers that have reached the IP addresses. By using the-D option, the router path is displayed more quickly because Tracert does not attempt to resolve the name of the router in the path.

Tracert generally used to detect the location of the fault, we can use the tracert IP in which link out of the problem, although still not sure what is the problem, but it has told us where the problem lies, we can be very confident to tell others----such a place out of trouble.
