This is a quick reference guide explaining the LCD screen options found on the AmpliFi HD router. All router screens can be turned off and their brightness adjusted, see this article for more.
Main
The main screen on the LCD display will have the time and date. You can choose between 12h and 24h mode in the app by launching the AmpliFi app, and selecting the router icon to access its Settings. Then navigate to General > 24-Hour Time.
Total Network Usage
AmpliFi will display the total upload and download on the entire network for a specific date range. The date range can be reset in the application, instructions on how to do so can be found here.
IP Address
WAN IP will be the public IP address, or the IP address of the gateway if AmpliFi is configured to be in bridge mode.
Speed
This screen provides information on the network's current upload and download speed. It is common to see 0.0 on this screen if there are no devices on the network currently uploading/downloading data.
Port Status
Each Ethernet port on AmpliFi will be displayed here. Highlighted means the port is active, whereas grayed-out means nothing is currently plugged into that port.
If you are using a router as a mesh point, you will have two additional screens. The first will be the mesh point's IP address, and the other is the mesh point's signal quality.
