The reasons and solutions for the laptop plugged in to the Internet but not connected to the Internet are as follows:

1.If the network icon is with an exclamation point, it isReasons for LAN instability,It is recommended to set a fixed IP address.

3.Eliminate the above hardware original causes, and then check the status of "Local Connection". If the icon of the local connection is two small computers flashing and prompting "connected", it means that the line from the switch hub to the computer is normal, the network card can basically work normally, and the inability to access the Internet is caused by improper operating system settings or software restrictions.

Use the ping command to ping the remote host to see if it can be pinged, if it can be pinged, it means that the network connection is normal, and then check the firewall settings in the computer, ** server.

You should go to the device manager to check whether the network card is working normally, and if not, use the driver life to update the network travel blind card god drive. Second, check whether the modem network is connected to the key split.

If the laptop is not connected to the Internet with a network cable, you need to check whether the network cable is connected properly, and you must also set the local IP address and DNS address. There are some campus networks that have infiltrated the Internet, because the local IP address is set or incorrectly installed, and they can't access the Internet.
