How to turn off Wireless power management permanently












14














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"
Mode:Managed Frequency:2.462 GHz Access Point: 00:00:00:00:00:00
Bit Rate=24 Mb/s Tx-Power=22 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
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.

                Key: powersave



                Type: uint32



                Default value: 0



                Can be one of:




                • NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2) (disable Wi-Fi power
                  saving)

                • NM_SETTING_WIRELESS_POWERSAVE_ENABLE (3) (enable Wi-Fi power

                  saving)

                • NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1) (don't touch currently
                  configure setting)


                • NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0) (use the globally
                  configured value)



                All other values are reserved.

                  TLP - Linux Advanced Power Management Tool works for me out of the box with Ubuntu 18.04.



                  > grep WIFI /etc/default/tlp 
                  WIFI_PWR_ON_AC=off
                  WIFI_PWR_ON_BAT=off

                  > iw dev wlan0 get power_save
                  Power save: off


                  FWIW. Ansible role is available to configure TLP with Ubuntu.

                        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.
