I just tested my SmartRG SR400ac with 17.01.4 and it works fine.

I also verified that plugging USB devices actually lights up the LED.

I see that ar71xx has an entry for WNDR4300:
ucidef_set_led_usbdev "usb" "USB" "netgear:green:usb" "1-1"
maybe it's not working for some reason?

After flashing the firmware, what's the output for
cat /sys/class/leds/netgear\:green\:usb/trigger
cat /sys/class/leds/netgear\:green\:usb/ports/*
