One nice feature is the ability to change the Wi-Fi frequency band used by each mesh point to communicate back to the router. It defaults to the faster 5GHz band and if the mesh point has a strong signal, all is well. However, if the signal is poor, you can try using the longer-range 2.4GHz band. My AmpliFi was perfectly happy with one mesh point using 5GHz and the other using 2.4GHz for its backhaul connection. Cool.
Note that whichever frequency band the mesh point is using to communicate with the router, it is available on both bands to communicate with your computers / phones / tablets.
I am a big fan of the Fing network scanner and running it on the AmpliFi Wi-Fi network turned up an interesting point. Each mesh point showed up in the scan with its own IP address. The app hides the IP address of the mesh points.
A Fing services scan showed that TCP port 80 was open on the mesh points, they were running a web server. So, of course, I tried to access one with a web browser. I was met with a simple web page that prompts you to download the AmpliFi app. The page also has a blue SUPPORT button. Clicking it, displayed the firmware version of the mesh point (this is available in the app) and a green button to download a file of diagnostic data. Nothing interesting.
More to come ...
