The orbi app is hosted on the router. But sadly, it rarely chooses the best test server. Its even worse at speeds >500mbps.
So if the server its choosing, is slow/bad, then your speeds show slow.
The ookla app lets you choose/change servers to test different test servers. Plus its built in default tends to choose better servers.
If you're hitting your full speeds using the ookla app, that's what I'd trust.
also in AP setup: RAXE500->EAX80
