I'm doing speedtest by ookla in the app from android and also from windows (when doing it via ethernet)

That measures the speed between your Android device and the Internet. It does not measure the speed between the Orbi router and the Internet or the satellites and the Internet.

If you use the Orbi app, you can measure the Internet Speed. That's the speed between the modem and the Internet.

The Orbi app also has a tile for WiFi Analytics. That will check the speed speed of the Wifi connection from the device that your Android device  is talking to.

You might like to check those measurements  to remove the Ookla app from the variables.

As CrimpOn​ says, a lot depends on how you measure things.

I'm wondering if maybe is there any setting that I would have to tweak to get an stable 350 mb up/down in all the my network?

That may depend more on the Android devices you are using than the Orbi system.

The difference is that the old ISP I didn't have access to the PPPoE credentials and I was unable to set Orbi as my main router, hence I had to use 2 routers.

With this new ISP I have access to the PPPoE credentials and I was able to put the ONT as bridge and use my orbi as the main router.

Hard to tell what is going on there. What is that ONT?

Just another user with time on their hands.
