my Wi-fi won't work after sleep. My card is Intel Corporation Wireless 7260 (rev c3).

/var/log/syslog says :

Mar  8 00:31:15 Laptop kernel: [ 1396.243632] iwlwifi 0000:02:00.0: Failed to load firmware chunk!

How to make it work ? :(

Thank you,

That card has some issues with iwlwifi driver in sleep mode.

You can turn off the power management with this command from terminal:

sudo iwconfig wlan0 power off

When you reboot your system you will lost this change, so if you want to make it pemanently, you must modify your driver configuration with the following commands:

echo "options iwlmvm power_scheme=1" | sudo tee /etc/modprobe.d/iwlmvm.conf

I recommend using the first option before making any final changes with the second option.
