Huawei Router AR120: Unable to Access the Internet After Successful Dial-Up?
If you have successfully dialed up but still cannot access the internet through your Huawei router, there could be several reasons for this issue. Here is a list of common issues along with their corresponding solutions:
Network Configuration Issues:
1、Physical Connection Check: Ensure that the WAN port (Wide Area Network port) on your Huawei router is correctly connected to your broadband device (such as an optical modem or DSL Modem). Make sure the physical connection is stable.
2、IP Address and Gateway Settings: Verify if the IP address and gateway settings in your router match those provided by your service provider. You can check these details within the router’s management interface under network settings or WAN settings.
Router Configuration Problems:
1、DNS Server Setting: Confirm that your router's DNS server settings are correct. This involves checking DNS servers within the router’s network settings via the management interface.
2、DHCP Functionality: Ensure that DHCP function is enabled on your router and that it properly assigns IP addresses. Within the router’s management interface, navigate to LAN settings and confirm DHCP server configuration.
Network Device Failures:
1、Router Reboot: Restart both your router and broadband devices (like an optical modem or DSL Modem) to ensure they initialize correctly.
2、Alternative Devices Testing: If other devices can connect normally, try using alternative networking devices like computers or smartphones to isolate whether the issue lies with the router itself.
Additional Tips:
- Refer to the local VPI and VCI values by accessing the internet to verify them. However, online resources often contain inaccuracies. Instead, use the following method to determine the VPI and VCI:
- Disconnect from dial-up connectivity and open a web browser. Try enteringhttp://192.168.1.1 to log into the router’s web interface. Enter the super administrator account credentials “电信” for the Telecom user, "cuadmin" for the中国联通 user, or any appropriate credentials depending on your service provider.
- Once logged in, look for the option to configure the broadband setup. Locate and delete all entries related to manual dial-up connections until no further dial-ups are possible. The remaining entry will be the one associated with your local VPI and VCI.
