This message is available from your computer, smart phone, or both.
The top one tells you if the power is on or not.
The next one down is your downstream. That is the signal coming in that is downloaded to your computer.
The next one is your upstream, the stuff that is uploaded to the internet.
The fourth one down is communicating with your internet service provider, to see if you're a subscriber or not, so it knows whether or not to connect you to the internet.
The fifth one is your LAN indicator. It blinks when data is being transferred to the upstream or from the downstream from a device or computer connected to your Local Area Network (LAN).
And of course your 2.4GHz and 5GHz tells whether or not the wireless function of your router is working or not.
