Troubleshooting and Solutions for Router Wireless Signal Not Detected

1. All Devices Cannot Detect Both 2.4G and 5G Signals from the Router:

   - Check if the router indicator lights are functioning properly. For instance, press and hold the WPS button on the router for 1-3 seconds and observe any changes in the indicator lights, or unplug and re-plug the internet cable into the router and observe the indicator lights.

    - If there is no change in the indicator lights, it indicates a router system failure. Contact the manufacturer for after-sales support or consider returning the router for servicing.

    - If there are changes in the indicator lights, it indicates that the router system is functioning normally. Try power cycling the router and check if the signals can be detected and connected to afterward. If the issue persists after the reboot, connect a computer to the router via an Ethernet cable, access the router's management interface, and check if the wireless signals are disabled or hidden. If no computer is available, consider resetting the router to its factory settings.

2. Some Devices Cannot Detect Both 2.4G and 5G Wireless Signals from the Router:

   - Check if the device is too far away from the router. Move closer to the router by 1-2 meters and see if the signals can be detected afterward.

   - Access the router's settings interface, navigate to "Advanced" > "Wi-Fi Settings" > "Channel & Bandwidth," and change the network mode for both 2.4G and 5G signals to exclude the 802.11AX protocol. Save the settings and check if the signals can be detected. If successful, update the network card driver for the device by using Driver Genius to automatically detect and install updates or manually download the latest driver from the network card manufacturer's website.
