What if broadband is often disconnected?

If you mean that broadband is often disconnected, I suggest that you can troubleshoot in the following ways.

Disconnect the router

If you use a router, please disconnect the router independent dialing test first.

Overheating equipment

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

Restart the computer

If you disconnect while running the program alone (for example, when playing a game), it is recommended to restart the computer and try or reinstall the program.

Check the line

If the whole network is disconnected, please check whether the access cable and network cable are loose or have poor contact, and then try to unplug the cable.

computer virus

Check and filter the broken network caused by computer virus, and scan it comprehensively.
