Hello, I am trying to calculate the upload speed of my WiFi network adapter. I have noticed that the value for the sent bytes (upload) is always double the expected value. I am running a speediest and my downstream is 30Mb/s. However, my upload speed in my app shows a little less than 8 MB/s which is actually double the value (it should be approx. 4MB/s).

It does not happen with Download speed.
