OK, options are interpreted. So the hwpctl=0 (or 1) does not have effect on my problem.
But ! Several minutes before to leave my work office this evening (in France), I add the options qos=0. And it seems that it was the solution ! I downloaded several GBs and I still connected :). I hope that I will have some time to investigate to learn how it doesn't work fine with this module option. Thank you very much for your help !!
