I've been using Powertop to extend my battery life. It suggests I enable wireless power saving mode with the following command:
echo 5 > /sys/bus/pci/drivers/iwl3945/0000:03:00.0/power_level
This command returns Permission denied no matter how I run it.
sudo cat /sys/bus/pci/drivers/iwl3945/0000:03:00.0/power_level returns
SYSTEM:auto MODE:fixed INDEX:1 What can I do?
