There are many possible reasons why Huawei routers have wireless networks but not wired networks.
First, it may be caused by the wireless network function turned on and the wired network function turned off in the router configuration.
Second, it may be caused by poor cable connection, port failure, or poor network cable quality.
In addition, there may be problems with the router's wired network Settings and parameter configurations, such as IP address conflicts or incorrect DHCP Settings.
Finally, it may be the fault of the broadband operator's line or the interruption of network service. To sum up, when users encounter similar situations, they can try to check and adjust the relevant Settings of the router, eliminate line and network cable problems, and consult the operator to solve the possibility of network service interruption.
