Greetings of the day,
Based on the description, the yellow light means that there are not clients connected on that specific Radio (5G or 2.4G) that depends where is the yellow light on.
This does not mean that the Access Point is broken or damaged.
Here is the meaning of each light on the Wireless Access Point
Yellows light 2.4G: Radio is up, no clients are connected to the 2.4 GHz radio.
Yellows light 5G: Radio is up, no clients are connected to the 5 GHz radio.
For detailed understanding of the issue, please let us know the LED status of the switch and the access points(PWR) using the below guide.
