The computer is often used and then disconnected

1. If you are referring to frequent broadband network disconnections, we recommend that you troubleshoot in the following ways:

If you are using a router, disconnect the router for stand-alone dial-up test first;

If you have a modem device, you need to pay attention to whether the device is overheating, you can turn it off for a few minutes and then restart it.

If the connection drops when running the program alone (compared to if it drops while playing a game), it is recommended to restart the computer to try or reinstall the program;

If the entire network is disconnected, check whether the access cable and the network cable are loose or in poor contact, and try to reseat the line.

Check and filter out the disconnection caused by computer viruses and scan the whole disk.

2. If the problem cannot be solved after the above troubleshooting, you can contact the manual customer service of the home location to report the problem.

The network is not good, or there is a problem with the routing.

Summary. Hello dear, glad for your question. 1.

678 errors. To put it simply, the network is not working.

Resolution. 1. First of all, confirm that the adsl modem dial-up is normal, because the IP automatically obtained by the network card is not cleared, so the network card cannot be obtained when dialing again.

After 5 seconds, right-click on the local connection to select Enable, and then turn on ADSL modem dial-up.
