"Hi Nick,\n \n\n\n\tThat's interesting. After some trial and error on my box, I also could not get it to work on kernel version 5.9.13 (21.02.0-trunk.16).\n \n\n\n\t \n \n\n\n\tWhat happens if you put the \"activity\" in the trigger file? If I do that on my box, it does seem to light up almost in the same cadence as the activity LED on the ethernet connector.\n \n\necho 'activity' | sudo tee '/sys/class/leds/helios64:blue:net/trigger'\n\n\n\tNote that this is not 'activity' of the network, but activity in the form of CPU activity. Not exactly what you are looking for, but this does seem to generate at least some action on the LED.\n \n\n\n\tGroetjes,\n \n"
