On the back of my ND555 unit the LED next to the LAN cable input, flickers in orange colour. What it indicates? Is it OK or a problem? Thanks
It’s fine. It’s just showing network activity and a connection speed of 100Mbps. Nothing to worry about.
And to be clear, a connection speed of 100 Mbps is what it is supposed to be. So that’s not just “enough”. By design it actually can’t be any higher.
