[Gilbert Dion <gilbertdion@xxxxxxxxx>]

I am sorry, I have no longer access to the computer on which this happened.
It belonged to a friend of a friend of mine and now the guy got back home
with it. He lives in another city. I can't even remember his name. Too bad!

Title:
  Wi-Fi not working after Sleep

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After sleep mode, the Wi-Fi chip is not recognized by the kernel
  module and therefore is not available. It is recognized after a reboot
  or after hibernating though.

  I have tried a lot of possibilities. Someone suggested the following command:
  sudo nmcli nm sleep false
  But it does nothing.

  This has nothing to do with the hardware Wi-Fi switch. I know its
  purpose and tried switching on and off.

  Also, the output of the command nmcli nm, nmcli c and nmcli d after
  coming back from sleep mode is showed below. Notice nmcli d shows no
  wlan1 device (which is how my wireless device is identified normally).

  eth1       802-3-ethernet    connecté 

  Last but not least, the output of dmesg | grep iwl  (after sleep) is 
  [  693.890526] iwl3945 0000:01:00.0: bad EEPROM signature,EEPROM_GP=0x00000007
  [  693.890532] iwl3945 0000:01:00.0: EEPROM not found, EEPROM_GP=0xffffffff

  [  693.890713] iwl3945: probe of 0000:01:00.0 failed with error -2

  And I think this tells it all.

  Ubuntu release 14.04 Ubuntu 14.04.2 LTS
  Wi-Fi chip is Intel 3945ABG and module is iwl3945.
