What is the principle behind blinking LEDs on a network card/WiFi?

Question

Iron

It would seem such a simple question, but it's still interesting how the LEDs blink. Obviously, this blinking is non-periodic, so it is probably tied to some processes taking place inside. Who knows?..

Answer 1

RX/TX

Answer 2

I don’t know about everyone, but in general there used to be 3 LEDs: green showed power, orange - 10Mbps connection, red - 100Mbps. The faster the red or orange blink, the more traffic is currently going (for receiving or transmitting).

Answer 3

Green - RX, yellow - TX

Answer 4

If 1 LED is of the same color, then sometimes there is the following blinking algorithm (by the way, not only wifi, but also, for example,
a cd / dvd activity light): while there is activity - the light flashes with a period, for example, half a second
* if the periods between activity are too short - they are smoothed out
* not only the blinking period is fixed, but the phase (shift, start) remains fixed
