WIFI LEDs do not shine

Software SW help
1

After update to TOS 6 the WIFI LEDs are not shining anymore. When booting up, when every LED is white, they are blinking, but after boot finished, they are off. I thought maybe purple is not allowed anymore, but also other colors do not work. Please also note the WAN LED is set to “always on” but it is blinking.
