to maximize the performance of my wifi connection I would like to disable Power Saving on my Intel 7260 PCIe board, but when I send the command
iwconfig wlan0 power off
I get the error
Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; Invalid argument.
I also tried with
sudo iw wlan0 set power_save off
but I get an similar error.
Is wifi power saving locked by a kernel setting?
