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, then we Ping two gateways, for example, Xiaobian here should be Ping 192.69.69.1 -t and then enter. The meaning of -t is to keep pinging.
4, if you want more accurate testing, you need to ping big bags or for a long time. 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, Ping gateway after the gateway we then ping 221.5.88.88 -t, this is Unicom's DNS, this delay will be relatively large, but not too much is normal.
6. If Ping passes through the gateway of the router, it means that the link between your computer and the router is normal. Otherwise, it indicates that there is 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.
