The computer network in our hotel is automatically acquired. Why can't computers connect to the Internet? The automatically obtained IP display address is 169.254.78.68. Help!

Hotels are generally tree networks, so most of the problems are on the switches, sometimes they are set up, sometimes the VLAN is different, and some may map the ports wrong.

This is your private address, not assigned by DHCP. This can only prove that there is nothing wrong with your computer and local network!

Is your network cable connected to the machine? Change it.

The most important thing is to see if this port on the switch is closed. If this is the case, it is definitely not available. In short, compare whether this port is in the same state as other ports. If all this is correct.

Another method you can use is to manually configure the IP address. First, check the IP number automatically obtained by other computers. Write one yourself, and be sure to be in the same network segment as the one automatically obtained. For example, other computers get192.168.1.102.

Then you can write192.168.1.xxx. In short, don't conflict with other IP addresses. If the connection is correct, see if you can ping the network management of your router, which is generally 192. 1. 1. Or192.168.1.254, which can be seen on good computers. Click Start → Run →CMD→ipconfig /all on the computer that can be used normally.

You will see everything.

If you can ping the same gateway, it proves that there is no problem. If you have any questions, remember to call me!
