Bonjour, The issue now is about wifi connections and usb (!!) If I plug an external usb harddrive, the wifi connection becomes awfull: I tested the rate of transfert from one computer to my updated laptop, using this: dd if=/dev/zero of=test bs=100M count=1; scp test me@laptop:/dev/null; Without any usb hdd plugged, the rate begins at 4.7MB/s and falls down to 2.4MB/s which is acceptable I think. With an usb hdd plugged (I tested with several devices), the rate quickly falls down to 100KB/s sometimes to 20KB/s and sometimes remains completely stalled. Moreover, the wifi connection is very often disconnected (even when there is no tranfert of data at all). Why do I think that it an update issue?: 1- because this behaviour did not happen before the update... 2- I have another laptop (exacttly the same, same brand, same model) which I did not update and this issue does not happen!

for this issue? I can exclude the kernel, because I tested the problem with the previous one (4.4.6) and NetworkManager* because I downgraded them.
