Looks like you anticipated my questions in the design= ! :) You're welcome! And more like you are running into the same problems I did myself originally, while running experiments quite similar to yours :) BTW, my full data set for my own WiFi experiments are here: https://www.cs.kau.se/tohojo/airtime-fairness/ https://www.cs.kau.se/tohojo/polifi/ The data files should also contain the Flent batch files and setup scripts; feel free to re-use anything you need :) -Toke
