Yes I have tried switching channels and didn't notice any difference.
Not sure where to find the information on Mbps but for speed I show 72.0 Mbps.
I'm using the hotspot functionality built into the phone.
Going to need you to exxplain how to do the screenshot.
I get a reading of 3.84 mbps 1.99 mbps 75 ms
Didn't get the screenshot to work but the reading after the *228 is: 6.09 Mbps - 5.28 Mbps - 71 ms
