how to know the internet speed of the client user

hi every one
today i make a nice experiment of how to know the internet connection speed status through the routerboard.
i asked one of my users to just connect to my access point without using internet
the result is as the image down

after a while i asked him to use internet ..the result is as image down

now
if we focus on the two images above ..we will see a difference numbers but my question is /
which is the most important parameter of the following parameters .we measure the internet speed of the client user ?
1-tx/rx rate
2- tx/rx packets
3-tx/rx bytes
4-tx/rx frames

You are watching the statistics. You must check the traffic for that user.

1-tx/rx rate >> show you the link capacity(nominal link capacity not the real)
2-tx/rx packets >> show you the transmitted / received packets
3-tx/rx bytes >> show you the transmitted / received bytes
4-tx/rx frames >> show you the transmitted / received frame

You should take a tour on Network + or CCNA. there are differences between these parameters.

You must check the traffic for that user.

need more explanation please..when someone connects to an access point and use that access point as internet gateway
the trafiic data will changed if that user did not use internet .
