Hi guys,
As I said I connect the A9 to the ASUS AC1200 earlier, and it was saying "Installing update" in the Google home app. I checked the A9 build-in website update history, there is nothing happened today. So I don't know what exactly the update was about.
Just 10 min ago, I was trying to switch the wifi to the NETGEAR ORBI by removing the product and add it again.
This time, the A9 was working with GOOGLE HOME and ORBI. The only difference comparing to what was before is that A9 is connecting to the satellite this time where it is closer to the main router...
Anyway, it is working now, I will setup another one and keep monitoring, like power cycling, if there is any crashes.
Update,
Use it for a while, it went standby.
Then it lost the Wi-Fi connection, I need to setup it all over again...
It just could not work with ORBI.
