Arnaud LE CAM, just to clarify, for 4.1-rc7 it works to your
expectations without having to use any WORKAROUNDS (i.e. fwlps/ips=0)?

I've been testing on several configurations :
kernel : 3.19.0-18 / 4.1-rc5 / 4.1-rc7
wifi (n/g)
options flags : fwlps (0/1) and ips (0/1)
It seems that it works exclusively with fwlps=0, regardless kernel version,
wifi or ips option (except with 4.1-rc7, where ips option should be set to 0
too).
Arnaud LE CAM, just to clarify, how long would you go without
interruption before the WORKAROUND?
Can I downgrade back to kernel 3.19.0-18 (setting ips and fwlps options to 0)
to keep a regular Ubuntu install ?
Feel free to test and advise if it changes anything.

Hi Christopher,
With those options, I'm connected without any interruption for 6 hours. So I
suppose it worked... Thank you for your help.
Few questions now :
Can I downgrade back to kernel 3.19.0-18 (setting ips and fwlps options to 0)
to keep a regular Ubuntu install ?
Should I do nothing else

My router connects with 802.11n at 150 mps (but the router also supports
802.11b and 802.11g).
