Configuring ORBI RBR50 with ATT Fiber

Now that I'm thinking about it -- the Orbi app as well as the router built-in speed test is probably pulling the results directly from the wired Router connection to the Arris gateway. In other words, it is NOT showing the actual wireless speeds, even if I using wirelessly connected devices.

For those that have the same ATT gigabit fiber connection with the same gateway + orbi router, what speeds are you getting when connected wirelessly? I guess I am expecting that with a faster internet connection that I should get at least the same wireless speeds as I got when I had Xfinity. It should not be slower (since I'm using the same Orbi hardware/setup), and if anything it should be much faster.

So in short, I have no speed problems when connected via a wired connection, but wireless connections run about half the speed (actually a little less) of wired. I've read other posts where users even have speed issues with wired connections but this is not my experience. And as I mentioned earlier, I don't think the Orbi app or the built in speed test within the Router actually reflects wireless speeds -- it's getting the speeds via the wired connection between the router and Arris gateway.
