The yellow light on the router may be caused by various reasons. Here are some common reasons and corresponding solutions: 1. Connection problems
1 WAN port not connected or poorly connected: - The yellow light on the router may indicate that the WAN port (i.e. broadband access port) is not connected to the network cable, or the network cable is not firmly connected. Suggest checking if the WAN port is plugged in with a network cable and ensuring a secure connection. If conditions permit, you can try replacing a short Ethernet cable for testing to rule out any issues with the cable itself.
2. Network interruption or failure: - When the router cannot connect to the Internet, the yellow light may also be on. At this point, you can check if the broadband service is working properly, or try restarting devices such as routers and optical modem. 2、 Router malfunction
1. Hardware malfunction: - Hardware malfunctions within the router may also cause the yellow light to illuminate. If the yellow light still stays on after excluding the above connection issues, it may be necessary to consider replacing the router.
2. Software or firmware issues: When there is a problem with the firmware (i.e. software) of the router, it may also cause the yellow light to light up. You can try restarting the router or follow the router manufacturer's guidelines for firmware updates. 3、 Set up issues
-Setting error: - Incorrect router settings may also cause the yellow light to turn on. It is recommended to check the settings of the router to ensure that all parameters are set correctly, especially the settings related to the WAN port. If the router cannot obtain a valid IP address from the ISP (Internet Service Provider), the yellow light may also be on. At this point, you can try resetting the router to factory settings and then reconfigure it. 4、 Router overload
-Too many device connections: - If the number of devices connected to the router exceeds its processing capacity, it may also cause the yellow light to light up. Suggest reducing the number of devices connected to the router or considering upgrading the router's performance. 5、 Other situations
-Normal network activity: In some cases, the flashing yellow light on the router may simply indicate that the device is processing or transmitting data normally. This is a normal manifestation of online activity, there is no need to worry.
-Firmware update prompt: Some router manufacturers use yellow lights to prompt users to perform firmware updates. Firmware updates can fix known issues, improve performance, or add new features. At this point, firmware updates should be performed according to the manufacturer's guidelines. Solution steps
1. Check connection: Ensure that the WAN port is properly connected to the Ethernet cable and try replacing the cable for testing.
2. Restart devices: Restart routers and optical modem devices to troubleshoot temporary issues.
3. Check settings: Check the settings of the router to ensure that all parameters are set correctly.
4. Firmware update: If the router prompts for firmware update, please follow the manufacturer's instructions.
5. Reduce device connections: If there are too many devices causing the router to overload, try reducing the number of devices connected to the router.
6. Contact technical support: If none of the above steps can solve the problem, it is recommended to contact the technical support team of the network service provider or router manufacturer for assistance.
By following the above steps, you should be able to diagnose and solve the problem of the router turning yellow. If the problem persists, please consider seeking more professional technical support.
