Why IT vendors are turning off LEDS on wireless access point

Access point manufacturers are trying to combine performance, design, and comfort when designing and producing new access points. About the design of the access points, some brands like Ubiquiti, Google OnHub or Linksys made a real effort and designed access points easy to merge within the décor.
Nevertheless, from a comfort point of view, consumers are complaining about the light-emitting diode (LED) mainly because they worry about the health effect of a blue light glowing all night and about the inconvenience of a LED shining in their eyes.
It is true that now, with the democratization of Wi-Fi, designers must adapt the product to different environments like hospital rooms, restaurants, dorm rooms, offices and so on.

Therefore, to maximize performance, it is better to put the access point as close as possible to the places where Wi-Fi users sit, stay, walk … so the story of the shining LED (that could sound like a whim) answers a real problem that must be taken into account by access points’ brands.
This LED, usually on the front part of the device, is used to convey information to the user about the device’s status. Each LED has its meaning, and it might change according to the device’s model. For example, the light is ON or flashing when the device is operating correctly, sometimes it changes color when there is a problem of connection, or it turns off when the device is not working.

Many vendors have already decided to turn off the LEDs on many access points, often remotely and at times without warning their clients. Reactions were almost all the same from consumers – “My access point is offline, the LED is not shining anymore.” In fact, without the light, a consumer might not know if his device is running correctly or if it has a connection issue, but explaining case by case that the device still works and that the LED is just turned off for comfort reasons is time-consuming. The only solution for the brands is to find a way to keep the communication with the consumer through the LED system without being annoying for them.
