How to turn off Wireless power management permanently
In Linux Mint 17.3 / 18 iwconfig
says the power management of my wireless card is turned on. I want to turn it off permanently or some workaround on this issue.
sudo iwconfig wlan0 power off
works, until I reboot the laptop.
Also, if I randomly check iwconfig
, sometimes it's on, despite I did run this command.
I read some articles about making the fix permanent. All of them contained the first step "Go to directory /etc/pm/power.d
", which in my case did not exist.
I followed these steps:
sudo mkdir -p /etc/pm/power.d
sudo nano /etc/pm/power.d/wireless_power_management_off
I entered these two lines into the file:
#!/bin/bash
/sbin/iwconfig wlan0 power off
And I finished with setting proper user rights:
sudo chmod 700 /etc/pm/power.d/wireless_power_management_off
But after reboot the power management is back on.
iwconfig
after manually turning power management off
eth0 no wireless extensions.
wlan0 IEEE 802.11abgn ESSID:"SSID"

Power Management:off
Link Quality=42/70 Signal level=-68 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:2 Invalid misc:18 Missed beacon:0
lo no wireless extensions.
I don't think this question applies only to Linux Mint, it is a general issue of particular wireless adapters.

Open this file with your text editor, let's use nano
for example:
sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
By default there is
wifi.powersave = 3
Just change it to a value of 2.
The change will be active upon the next reboot.
The values for the powersave field are:
NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value
NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1): don't touch existing setting
NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave
NM_SETTING_WIRELESS_POWERSAVE_ENABLE (3): enable powersave

It is not sufficient to turn off wireless power management at boot.
There are probably hooks like if I plug off power adapter.
So one of possible solutions is as follows; step-by-step.
Create a directory, where you wish to store the file, if not already having one for all your scripts, I personally want to have it in /etc/pm/
:
sudo mkdir -p /etc/pm/power.d
Create (anywhere you like) a script, name it to be sensible, for me it is:
sudo nano /etc/pm/power.d/wireless_power_management_off
I used nano
, but use whatever, e.g. if you want to create the file graphically, eg. with gedit
(LM17) or xed
(LM18):
gksudo gedit /etc/pm/power.d/wireless_power_management_off
gksudo xed /etc/pm/power.d/wireless_power_management_off
Enter the following contents to the file:
#!/bin/bash
/sbin/iwconfig wlan0 power off
Save the file.
Owner of the file should be root
, if you created the file as normal user somewhere, go to the folder where it is and fix it with:
sudo chown root:root wireless_power_management_off
Next, you need to set proper permissions to the file, rwx
for owner:
sudo chmod 700 wireless_power_management_off
Finally we will be executing the script every minute using CRON; dirty but worky:
sudo crontab -e
If you never edited crontab
before, it will ask what editor you wish to use, this is totally up to you.
Paste this to the end of the file:
*/1 * * * * /etc/pm/power.d/wireless_power_management_off
Wait a minute and then you may check if power management if turned off:
iwconfig wlan0 | grep "Power Management"
Example output:
Power Management:off
Even if something triggers the power management to turn on, it will last only a minute. Done.
