Orbi rbk50

There are a few possible explanations. Wifi interference is one. When you run the speed test on the Orbi app, I think it's just displaying the results of the speed test run directly on the Orbi, and your phone is just the video output for it, basically. Try running a speed test directly on your phone, rather than through the Orbi app. It's probably ideal to use the Ookla speedtest app, since that's the same service the Orbi uses. Ideally, you should also disconnect or power off any other devices on your network, so you can be sure they aren't sucking up any of your bandwidth while you test. And, given that your modem is a combo modem and router, you should either set the C6300 to bridge mode and the Orbi to router, or the Orbi to AP mode and the C6300 to router. Having both route can cause problems. Also, the C6300 should have the wifi disabled, regardless of whether you use the C6300 or the Orbi as your router. Or, at least, give the wifi networks on the Orbi and C6300 different names, and have them use different channels to minimize their interference with each other.

Also, on your laptop, there are a couple things to try and/or check. First, reboot. Also, check which standard your NIC is (e.g., 802.11n, 802.11ac, etc.). Also, which band it's connected to the Orbi with (5 GHz vs 2.4 GHz). On Windows, this is easy enough to determine. Click the wifi icon down by the clock, then find your wifi network you're connected to and click properties. Then scroll down and it'll tell you the SSID, protocol, and network band and channel. If you're testing with the laptop over wifi, it'll also matter how strong the wifi signal is and how close you are to the router. Finally, are you connected to the router directly, or via the satellite? Does the satellite have a strong signal to the router? These you can both find out from the Orbi web configuration page. The Orbi app will show whether you're connected to the router or satellite, but I don't think it shows you the quality of the backhaul connection between the router and satellite. So, if, for instance, your laptop is connecting to the satellite, and the satellite has a poor wireless backhaul to the router, that could explain the disparity between the Orbi's speed test results and your laptop's. You can also try removing the Orbi's network from your laptop and then re-adding it (not disconnecting from it, but removing or "forgetting" the network, so that you have to type in the password again before it'll work).

I'd probably do a progression of tests, starting with one directly connected to the modem, bypassing the Orbi completely, over ethernet. Then, one connected to the Orbi router over ethernet (ideally, with the satellite unplugged, any devices connected by ethernet to the router unplugged from the LAN ports, and any other wireless devices powered off so that, for practical ppurposes, your home network consists of your modem, your Orbi router, and your testng device, and nothing else. Then router via wifi. Then the satellite via eithernet (if you have a satellite with ethernet LAN ports). Then, finally, satellite via wifi. If you're getting 100+ Mbps for the first couple tests (going in the order I listed them), an then it drops off on the next one, that's probably where the problem is.
