I just upgraded my Internet service from 50 to 150 Mbps. When I test the speed using the Deco app, it reflects the new bandwidth, but when I run Speedtest on any of the devices, including the iPhone running the Deco app, it's still at the old speed. I rebooted the network and for one test on the iPhone I got close to full bandwidth, but all subsequent tests are back to the same 45 Mbps. What can I do to get closer to full bandwidth?

Devices: MacStudio M1 Max, Macbook Air M1, iPhone XR, iPad Air (4th gen)
