Router broadband dial-up internet connection failure may be caused by various reasons. Here are some common solutions and troubleshooting steps: 1. Check basic settings
1. Confirm that the broadband account password is correct: - Ensure that the entered broadband account and password are correct and comply with the format requirements provided by the operator- If you are unsure if the account password is correct, you can contact the operator's customer service for inquiry or reset.
2. Check the network line connection: - Ensure that the broadband line (such as optical fiber, ADSL, etc.) is correctly connected to the WAN port (Internet port) of the router- Check if the network cable is securely plugged in without any looseness or damage- If possible, try replacing a new network cable for testing.
3. Check router settings: - Enter the router management interface and check if the internet access method is set to PPPoE dial-up (ADSL users usually choose this method)- Ensure that other settings of the router (such as DNS servers, MAC address cloning, etc.) are consistent with the configuration provided by the operator. 2、 Attempt to restart the device
1. Restart the router: - Power off the router for a few minutes and then reconnect it, waiting for the system to restart. This can solve some temporary malfunctions caused by prolonged device operation.
2. Restart optical modem or modem: - If the router is connected to optical modem or modem, you can also try restarting these devices. 3、 Further investigation
1. Check the status of the optical modem: - If using the optical modem, please confirm that its DHCP server is functioning properly. You can try directly connecting to the WiFi or wired connection of the optical modem for testing.
2. Dial up directly from the computer: - Connect the Ethernet cable plugged into the WAN port of the router directly to the computer and use the built-in broadband connection for dial-up testing. If the computer can successfully dial up to the internet, it means that the problem may be with the router; If the computer cannot dial up to the internet, it may be a problem with the broadband line or carrier.
3. View router logs: - Enter the router management interface and view the system logs for more information about dial-up failures. The log may display error codes or prompt messages, which can help further locate the problem.
4. Contact the operator: If none of the above steps can solve the problem, it is recommended to contact the operator's customer service for consultation and troubleshooting. Dialing failure may be caused by equipment failure, line issues, or account restrictions on the operator's end. 4、 Other precautions
-Ensure that the router firmware is the latest version to avoid dialing failures caused by firmware issues.
-If the router has been in use for a long time and frequently experiences dialing failures, you can consider replacing it with a new router.
-During the troubleshooting process, please be patient and careful, and follow the steps to investigate possible problem points one by one.
