thanks dear mohanak,

I have this table but at the end you find 3g/4g led (only green color is mentioned)

what about orange or yellow blinking?

 

Did you ever find an answer to this. We have one unit doing the same.

Seems to be working ok, but would like to know what the orange led is for as all documentation says green.

same issue, any news about the reason of the yellow blinking led?
