Title:
Wi-Fi not working after Sleep
Status in linux package in Ubuntu:
Invalid
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).

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.
