Installed connect app but when i go on broadband section it doesnt show my boosters ,shows hub and tivo boxs but not boosters
Might be worth checking you have setup the boosters correctly
If the boosters are using the same SSID then that will be expected, it's just boosting the same visible WiFi network.
What you should notice is that your WiFi signal on your phone or similar is at the maximum when you are right next to the booster.
You can use an app like WiFi Analyser or similar to look at the WiFi strength in different areas.
