If the computer broadband connection can't be opened, we can't surf the Internet normally. What should we do? Next, I sorted out the relevant methods of why the computer broadband connection can't be opened for you. I hope it will be helpful to you!
1. The network cable is disconnected. First, check whether your cable is disconnected, because sometimes you inadvertently disconnect the cable, resulting in failure to connect.
2. The modem is disabled. The modem is disabled. This may be set by yourself or the device system itself. Just turn it on.
3. The modem driver is corrupted. The driver is damaged due to its own or external factors, so you need to replace it for a long time.
4. Spyware is running on your computer, which is preventing the connection. When the computer runs some spyware, it will cut off your network and hinder broadband connection.
5. Winsock needs to be fixed. This is the simplest. Repair it and wait for it to be repaired.
6. Third party firewall software blocked the connection. Open your system management main panel page and find out whether there is a third-party firewall software to block the connection to the network. If so, just unblock it. This is the most common reason.
