The specific method is as follows:
1. Click Start, type cmd in the search box, and then press Enter. For WinXP system, you must first click Run, then enter cmd, then press Enter.
2, we first enter ipconfig /all, then enter to see. There will be a lot of things popping up, and we just need to find information that is useful to us. Mainly look at the router's gateway and the operator's gateway. Please see the image logo for details.
3, and then we were about Ping two gateways, such as small series there should be input Ping 220.127.116.11 -t and then press Enter. The meaning of -t is to keep pinging.
4, if you want a more accurate test, you need a large bag or Ping time longer. After a few minutes, hold down Ctrl+C on the keyboard and stop it to continue pinging. Let's take a look at the status of the network connection. Mainly look at two places, one is to see if there is no packet loss, and the second is there is no delay. The picture loss rate is 0, but there are some delays, but it is not a big problem for the home, it is normal.
5, after Ping gateway router we'll Ping 18.104.22.168 -t, this is China Unicom's DNS, this delay will be relatively large, but not too much is normal.
6, if Ping through a gateway router, indicating a link between your computer and the router is normal, on the contrary, it indicates a problem with this link. If the ping router is normal, the dns of the operator is pinged and the ping is found to be different. This is usually a problem between the router and the carrier.
