[Bug 1565106] Re: Wifi works on W10 but not on Ub 16.04 nor 14.04

 

after installing new kernel 4.7, RJ45 connected
I rebooted a first time (on 4.7)
took RJ45 out
no wifi

I connected RJ45 to install Chromium
rebooted a 2nd time, RJ45 out, no wifi

I rebooted a 3rd time, RJ45 out, wifi was visible (see the picture below)

I did not connect to my wifi box (no wifi password declaration)
rebooted
no wifi again

I shut-off / shut-on power supply
wifi is back
I've been connected to it (see picture below)

I shut-off / shut-on power supply again to check a 2nd time
NO wifi

I reboot
NO wifi, same

Finally, as usual, when I do a major change (reinstall, but no improvement this time) or upstream kernel, I've got Wifi just ONCE which means my card is recognized by Ubuntu, but never again.
Looks like a sort of flag is marked somewhere which no longer allows wifi

Title:
  Wifi works on W10 but not on Ub 16.04 nor 14.04

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Hi
  I just bought a laptop "HP Envy x360 15-w100nf". Everything's fine except wifi
  - It works on w10
  - but not on Ub 16.04 / 4.4.0-15 / 64 bits
  - nor Ub 14.04

  I've spent hours of discussions and tests on wifi forum
  URL = https://forum.ubuntu-fr.org/viewtopic.php?id=1987186
  (unfortunately it's in French but command line tests are quite understandable)

  Now I think nobody can help me on the forum because we've tried everything, that's why I assume it's a bug.
  I'm ready to make every test which could help solving this problem

  In the meantime, have a nice day (actually a nice night ... in France !)
